All About COSMOS Motion
Thursday, September 27, 2007
What is COSMOS Motion?

COSMOSMotion is a rigid body kinematics and dynamic simulation software that is fully integrated in SolidWorks.

COSMOSMotion simulates the real life working of your mechanism.

It is used by students, designers, engineers and other professionals to produce efficient and optimized designs.


Traditional Design Cycle

Use SolidWorks to build the model.

Manufacture a prototype.

Test the model under various conditions. Instrumentation is needed in most cases.

Based on the results, modify the model in SolidWorks, build a prototype, and test again until you are satisfied with the design.

Send the drawings to manufacturing.


Design Cycle with COSMOSMotion

Use SolidWorks to build the model

Use COSMOSMotion to test the model virtually on a computer

Based on the results, modify the model and simulate until you are satisfied with the design

Build the prototype for further testing

Send the drawings to manufacturing

Benefits of using COSMOSMotion

Reduces the number of prototypes needed for testing

Reduces the design time and therby time to market

Reduces the engineering design cost due to physical testing

Optimize yours design by quickly simulating many concepts and scenarios before making a final decision

What can COSMOSMotion do?

Determine how the mechanism (assemblies) will move

Find Clearance/Interference through entire range of motion

Determine how forces effect the mechanism

Determine reaction forces, spring forces, loads, torques, accelerations, velocities

Create trace path and Cam profile

Size actuators, motors, springs and dampers

Provide loading information for design validation


What is Motion Simulation?

How parts in an assembly will move is determined by:

–Joints connecting the part

–Driving motions applied to joints

–The mass properties of parts

–Applied Forces to the system (Dynamics)

–Time

COSMOSMotion allows you to input these parameters and show you how parts in an assembly will move

Key Engineering Problems addressed by COSMOSMotion

Size motors and actuators

Determine power consumption

See how friction will increase power requirements and actuators size

Design Force Transmission

Spring and damper stiffness

Design Hydraulic actuators

Reduce vibrations. Understand imbalance effects on mechanisms

Determine boundary conditions for stress analysis

Joints

A Joint is used to constrain the relative motion of a pair of rigid bodies by physically connecting them

Joints are automatically created from SolidWorks mates

COSMOSMotion also allows users to create joints manually

Types of Motion

Free

Displacement

Velocity

Acceleration

Displacement, Velocity and Acceleration can be constant or a function of time

Types of Functions: Step, Harmonic, Spline and Expression

Spring and Dampers

Types of Springs in COSMOSMotion

–Translation Spring

To show cosmetic thread in the Model
Wednesday, September 26, 2007
How to show the Cosmetic thread for a feature while creating Model ?

1) First We have to begin with the bare bolt using Extrude feature shown in Fig:1


Fig:1

2) Sketch a line where the thread ends in the bolt with Sketch --> Line and dimension that line as shown in Fig:2

Fig:2

3) In the Insert menu,Curve -->Split line option and select the cylindrical surface of the bolt.Then the cylincrical feature turns into two face segments ie. Surface Split shown in Fig:3

Fig:3

4) Right click on the thread surface side of the surface split, Change the Texture Appearance option.Select the thread texture and vary the spacing,angle to illustrate left or right hand threads,number of starts also.We can also rotate the thread texture to match with the circumference of bolt dia.


Fig:4

5) Then add the standard thread note to the threaded surface using Insert-->Annotation-->Note shown in Fig:5

1:1 Scale View of a model on your Solidworks Screen
Wednesday, September 19, 2007
How to scale the model for 1:1 in Solidworks Screen?

Sometimes it is difficult to gauge scale on your CAD model. Small objects can seem huge because you have zoomed in so close in order to model the feature.we have found the following technique particularly helpful in modelling human scale products, or more specifically - objects and features within the envelope of your monitor screen. Even large products tend to have smaller human interfaces so this tip could be useful to a lot of people.Go to one of the orthographic views. First find a reference length. In this case the length of the battery is 106mm.


Then I set my callipers to the reference length (106mm).

Zoom the view to match the length on your calliper. Already we can see that the battery is a lot bigger than we had expected it to be.


After matching the length, do not move or zoom your view. Create a new view and name it 1:1 scale.

As long as you dont zoom in, you should be examining a 1:1 scale model on your monitor. Just rotate the viewport/camera to observe from all angles. At the very least this method can save you a few printouts to confirm scale. we use it to quickly gauge the ergonomics of a CAD model before sending to rapid prototype.

Feature Driven Patterns in Solidworks 2007
Wednesday, September 12, 2007
To use an existing pattern to create a pattern of components:

1) You can place a pattern of components in an assembly based on a feature pattern of an existing component.This is called Derived Component Pattern.

2) You can place a pattern of components in an assembly based on a feature pattern of assembly features.

3) By default, all instances use the same configuration as the seed components. To change the configuration, edit the component properties of an instance.

4) You cannot skip instances when creating a derived component pattern; you must edit the feature.

5) The new components appear under DerivedLPattern or DerivedCirPattern in the FeatureManager design tree

This is an useful video Tutorial from Solidprofessor which shows the Feature Driven Pattern in a particular Assembly.

Sheet Metal Forming Tool
Tuesday, September 11, 2007

How to create a New Sheet Metal Forming Tool?

You can easily create your own forming tools using the Forming Tool command in SolidWorks 2007. First, create a part file with the features for the forming tool, as shown in Figure1 .

Figure1

In order to create a forming tool, pull down the “Insert” menu and pick Sheet Metal Forming Tool or click Forming Tool in the sheet metal tool bar.

In the graphics area, select the top of the part where the lances are located for the Stopping Face. No base is required to create forming tools. Then, for the Faces to Remove, select both sides of the extrusion, as shown in Figure 2.

Figure 2

The Orientation Sketch and the colors that identify the stopping faces and the faces to remove are added automatically. Once you save the part to the forming tools folder in the Design Library (\data\design library\forming tools), you can add the forming tool to a sheet metal part, as shown in Figure 3.

Hole Wizard Tips
Monday, September 10, 2007
Hole Wizard Pre-selection Versus post-selection

There are two ways to use the Hole Wizard in SolidWorks. You can either select the plane or face to create the hole on before or after you select the Hole Wizard command. (Click the Hole Wizard icon from the "Features" toolbar, or pull down the “Insert” menu and pick Features – Hole – Wizard).

What's the difference? A 2D sketch is created when you pre-select a planar face for the Hole Wizard. A 3D sketch is created if you first click Hole Wizard and then select a face. To help understand what this really means, take a look at the simple L Bracket below. For the 1/4" diameter hole on the left, the left side of the part was selected as the planar face to create the hole on (pre-selected), and then the Hole Wizard command was picked. For the 1/4" diameter hole on the right, the Hole Wizard command was picked and then hole location was defined (post-selected). Both holes were dimensioned .50 from the side of the part and 1.00 from the bottom of the part. Note the difference in the screen captures below.

For the L Bracket, a 2D sketch is desired to get the distance from the bottom of the part to the center of the hole. The 3D sketch actually dimensioned from the edge line of the part to the center of the hole, causing an inaccurate dimension (the direct vertical distance is actually .9798). If you would like to use a 2D sketch, which would dimension to the projection of the edge instead of the actual edge, you just need to select a face before selecting the Hole Wizard command.

How to Hatch a Model in 3d
Saturday, September 8, 2007
A Better Way To Hatch in 3D

Sometimes you run into a situation where you want to hatch faces in a model to show on a drawing sheet. If you do this with the regular 2D manual hatching tool and just click on faces, they will show through the unhatched faces of the model like this:



A better way to do this is to take advantage of textures in the 3D model. By adding a texture (and you can make your own) you can essentially hatch directly on the model in 3D and simply show the model that way by making the view shaded in the drawing sheet, like this:

Foreshorten the Radius and linear dimensions in Solidworks
Thursday, September 6, 2007
How to show Foreshorten Radius and linear dimensions in Solidworks drawing?

Foreshortened radius specifies that the radius dimension line is foreshortened (broken). This is helpful when the centerpoint of a radius is outside of the drawing or interferes with another drawing view.

When you dimension to a foreshortened radius or diameter, the dimension also appears as a zigzag in the ANSI standard.

This is a video tutorial which depicts how to show the foreshortened radius and linear dimensions.

Use of ALT key in Solidworks
Wednesday, September 5, 2007
Use ALT keys to improve the speed and productivity of your design

  • In a Drawing you can move a view by using the ALT key. By selecting anywhere in the view as opposed to a model edge or the view edge.
  • In a Drawing, holding the ALT key you can move any table from anywhere on the table as opposed to only the move control cell in the upper left hand corner.
  • In an Assembly, the ALT key can be used to “Drag & Drop” mates, using Smart Mate technology. These mates include Coincident (Planar Face to Planar Face), Concentric (Cylindrical Face to Cylindrical Face), and “Peg in Hole” Coincident & Concentric combined (Circular Edge to Circular Edge).
  • Alt + Left or Right Arrow keys rotate the model in a Clockwise / Counter Clockwise fashion.
  • When re-ordering the sequence of Parts in an Assembly, the Alt key prevents the dropping of a Part into an Assembly
  • When several Dimensions are grouped on a Drawing, if you want to adjust one dimension in the group, you can hold the ALT key and drag it to the new location, while maintaining the group.
