When you generate a model for a moving object, the simulated object may need an initial translational speed of 1,300 mm/s or an initial rotational speed of 10 rad/s.
For example, suppose there is an object that is moving along the X-axis at a speed of 1,000 mm/s and you want to model how the object moves when exposed to gravity.
In this case, you need to apply an initial velocity to the body.
MBD for ANSYS allows you to set the initial velocity of a body in its Details window. To do so, perform the following steps:
- Use the Define Body function to create a user-defined body.
- In the Details window, in the Initial Velocity Information pane, set either the Translational Velocity or Rotational Velocity to Yes. (If necessary, you can also set both options to Yes.)
- Enter the initial velocity values in the X, Y, and Z fields.
When you perform the simulation after setting the initial velocity, the initial velocity is applied to the body at 0 seconds. (The initial velocity function is useful in simulations where, for example, an external force is applied to a body that is rotating at a speed of 100 RPM.)
