What You Will Create and Analyze
During this tutorial, you analyze and modify an assembly of a front suspension and steering subsystem. To perform the analysis, you must first create a double-wishbone suspension and steering subsystem from standard Adams Car templates and subsystems. Adams Car templates define a subsystem’s topology and specify how one subsystem connects to another. Templates also contain default parameters, such as locations, part masses, and inertias.
The figure shows the suspension and steering assembly (in shaded mode) that you will analyze and modify.
Figure 1 Suspension and Steering Assembly
After you create the suspension and steering assembly, you perform two types of analyses to understand its kinematics:
■A baseline parallel wheel travel analysis that moves the assembly vertically through the suspension’s rebound-bump travel.
■A baseline pull analysis to measure the brake pull at the steering wheel.
Once you understand the kinematics of the assembly, you modify the suspension subsystem’s geometry to decrease the scrub radius, which should reduce the pull on the steering wheel. You confirm the reduction by analyzing the modified assembly again, using the same type of analysis and comparing the new results to the results yielded by the previous analysis.
