Tire Envelope Analysis

This is a quasi-static simulation during which the suspension is exercised to the extremes of ride and steer travel for doing packaging studies.

At tabular report containing the wheel center and spindle alignment points for the various positions is created.

Required input

Suspension travel:

Jounce and rebound travel specified in the form of wheel center displacements, shock/strut displacements, or ball joint displacements.

Steering travel:

Maximum and minimum steering travel at different suspension positions.
Number of output steps at a ride height.
Number of solver steps between successive ride heights.

Task Description

The suspension is exercised to the extremities of steering travel at various ride heights between jounce and rebound. Jounce and rebound travel can be specified in terms of wheel center displacements, shock displacements, or ball joint displacements.

Output

A tabular report summarizing the wheel center point and the spindle alignment points for the various positions is generated. This data can be used for tire envelope packaging studies.
