Types of Suspension Analyses

The suspendsion analyses include:

The types of analyses that you can run on a suspension are:

(1) Wheel Travel Analyses:

A wheel travel analysis allows you to look at how the characteristics of a suspension change throughout the vertical range of motion of the suspension.

You can perform three types of wheel travel analyses, as explained in the next sections. As a minimum, all wheel travel analyses require a suspension subsystem. These analyses can also include a steering subsystem.

Ÿ Parallel Wheel Travel Analysis

Ÿ Opposite Wheel Travel Analysis

Ÿ Single Wheel-Travel Analysis

Parallel Wheel Travel Analysis:A parallel wheel travel analysis keeps the left wheel and right wheel heights equal, while moving the wheels through the specified bump and rebound travel.

Opposite Wheel Travel Analysis:An opposite wheel travel analysis moves the left and right wheel through equal, but opposite, vertical amounts of travel to simulate body roll. The left and right wheels move over the specified jounce and rebound travel, 180 degrees out of phase with each other. You specify the parameters to define the vertical wheel travel and the fixed steer value when you submit the analysis.

Single Wheel-Travel Analysis:A single wheel-travel analysis moves one wheel, either the right or left, through the specified jounce and rebound travel while holding the opposite wheel fixed in a specified position.

(2) Roll & Vertical Force Analysis

A roll and vertical force analysis sweeps the roll angle while holding the total vertical force constant. The total vertical force is the sum of the vertical forces on the left and right wheels.

In contrast to the opposite wheel travel analysis, the roll and vertical force analysis allows the wheels to seek their own vertical position.

(3) Steering Analysis

A steering analysis steers the wheels over the specified steering wheel angle or rack travel displacement from the upper to the lower bound. A steering analysis requires a suspension subsystem and a steering subsystem.

(4) Static Load Analysis

Depending on the type of load you input, the static load analysis applies static loads to the spindle and the tire patches between the specified upper and lower load limits. A static load analysis requires a suspension subsystem.

(5) External-File Analyses

There are two types of external-file analyses: loadcase and wheel-envelope analysis.
