Event-based Motion Analysis

With SolidWorks Simulation® Professional added in, you can use Motion Analysis to calculate the motion of an assembly that incorporates event-based motion control.

Event-based motion requires a set of tasks. The tasks can be sequential or can overlap in time. Each task is defined by a triggering event and its associated task action. Task actions control or define motion during the task.

A task trigger is the event that drives the motion control action for a task. You can define task triggers based on time, previous tasks, or sensed values, such as component position.

You can create triggers from:
  • Sensors:
    Interference detection
    Detects collisions.
    Proximity
    Detects motion of a body crossing a line.
    Dimension
    Detects the relative position of components from dimensions.
  • Previous tasks in the event schedule
  • Start and finish times for task actions

A task action defines or constrains the motion of one or more components in the assembly. You can define actions to suppress or activate mates, stop motion, or to change values for motors, forces, or torques.

You can define a task action to:
  • Start, stop, or change the value of a constant speed motor, constant force, constant torque, or a servo motor
  • Stop the motion
  • Suppress a selected mate

To use event-based motion, you must:
  • Obtain a SolidWorks Simulation Professional license.
  • Add in SolidWorks Motion.
  • Select Motion Analysis for the motion study type.
