From the Function Builder, you can define motor or force profiles from expressions combining functions of time, existing results, or cycle angle.

Some Function Builder options are not available for Animation or Basic Motion study types.

From the Motor or Force PropertyManager, under Type, click Expression
.

Select the function Value:

Displacement

Velocity

Acceleration

For path mate motors in Motion Analysis type studies, select from the following:

Distance Along Path

Tangential Velocity

Tangential Acceleration

Enter the function in the Expression Definition area by typing the function or by selecting from the Expression Elements list:

Mathematical Functions

Variables and Constants

Motion Study Results

The lower right corner of the Expression Definition area indicates expression validity:

You can combine expression elements with ordinary mathematical operators: +, -, *, / and **.

For example, to enter an expression for

sin(t)e^{-3t}

From Mathematical Functions, double-click Sin(a).

From Variables and Constants, double-click Time.

Click outside the parentheses and enter *EXP(-3*Time).

For motor profiles, you can view displacement, velocity, acceleration, and jerk in the Function Builder. For force profiles, you can view a plot of the force profile.

Click OK.

Before clicking OK, you can select Make function available to define other motors or forces for this model and enter a function Name. The function name appears in the PropertyManager.

To specify units of degrees for calculated expressions, click Unit System > Edit Document Units (Status bar), and for Angle, select Degrees.

SOLIDWORKS Motion supports many functions and expression functions. You can enter these functions in the Expression boxes of the Motor or Force PropertyManagers.
