Motion Analysis Overview

You can use Motion Analysis (available with the SOLIDWORKS Motion add-in from SOLIDWORKS Premium) to accurately simulate and analyze the motion of an assembly while incorporating the effects of Motion Study elements (including forces, springs, dampers, and friction).

A Motion Analysis study combines motion study elements with mates in motion calculations. Consequently motion constraints, material properties, mass, and component contact are included in the SOLIDWORKS Motion kinematic solver calculations.

A Motion Analysis study also calculates loads that can be used to define load cases for structural analyses.

To use the SOLIDWORKS Motion solver in a motion study, select Motion Analysis from the motion studies type list in the MotionManager.

  • Degrees of Freedom

    An unconstrained rigid body in space has six degrees of freedom: three translational and three rotational. It can move along its X, Y, and Z axes and rotate about its X, Y, and Z axes.

  • Integration Methods

    A set of coupled differential and algebraic equations define the equations of motion of a SOLIDWORKS Motion model. A numerical solution to these equations is obtained by integrating the differential equations while satisfying algebraic constraint equations at every time step.

  • Detecting Interference

    You can use Motion Studies to check for interference in your design as the parts move. You can check any of the components in your SOLIDWORKS assembly model, regardless of whether a component participates in the motion model.

  • Find Interferences Over Time Dialog Box

    Check components for interference as they move.

  • Advanced Motion Analysis Options Dialog Box

    You can select advanced integration options in this dialog box.

  • Interpolation Method Comparison

    You can select from three interpolation methods when you provide a data set to define force, torque, or motor profiles: Akima Spline, Cubic Spline, or Linear. The interpolation method you select is used to define the profile function between data points.

  • Motion Along a Path

    You can include path mates in Motion Analysis studies.For Motion Analysis studies, you can define a path mate motor to specify displacement, velocity, or acceleration values as a body moves along a path.

  • Exporting a Motion Study to ADAMS

    You can create an ADAMS dataset (.adm) file of a Motion Analysis type motion study. Exported ADAMS data includes the .xmt_bin files for part geometry, and the motion study features listed in the MotionManager tree.
