|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)
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
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
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
–Non linear Spring
Types of Dampers in COSMOSMotion
– Translation Damper
– Torsion Damper
– Non linear Damper
Types of Forces
–Action only force
–Action only moment
Create the model in SolidWorks and apply materials
