A kinematics motion simulation shows the physical positions of all the parts of a mechanism, with respect to time, as the mechanism goes through a cycle. This type of analysis determines the range of values for displacement, velocity, acceleration, and the reaction forces on constraints.
In a kinematics simulation:
Gravity and mass properties are not considered.
External loads and inertial forces affect reaction forces at constraints but do not affect motion.
Bodies and joints are assumed to be rigid.
Bushings and contacts are not available.
This type of analysis is typically used to evaluate motion for interference between components, such as assembly sequences of a complex mechanical system.
In a dynamics simulation:
Gravity and mass properties are considered.
External loads, forces, and torques (linear and nonlinear) can generate motion.
Bushings are available for simulating compliant joints.
Contact and friction effects are available.
Flexible Body Dynamics, Motor control and MATLAB Simulink co-simulation features are available.
