2. What is COSMOSMotion?
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

3. 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

4. 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

5. Benefits of using COSMOSMotion
Reduces the number of prototypes needed for testing
Reduces the design time and thereby time to market
Reduces the engineering design cost due to reduced physical testing
Optimize your designs by quickly simulating many concepts and scenarios before making a final decision

6. 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

7. 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

8. 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

9. 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

10. 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

11. Spring and Dampers Types of Springs in COSMOSMotion
Translation Spring
Torsion Spring
Non linear Spring
Types of Dampers in COSMOSMotion
Translation Damper
Torsion Damper
Non linear Damper

12. Types of Forces Gravity Applied Forces Action only force
Action only moment
Action/Reaction force
Action/Reaction moment
Impact force

13. Analysis Steps Create the model in SolidWorks and apply materials
Select Fixed parts and Moving parts
Automatically derive joints from SolidWorks assembly mates
Define motion to the joints
Create springs, dampers, forces if needed
