Simulation analysis of a double-wishbone front suspension's K&C characteristics based on ADAMS

The kinematics and compliance(KC) characteristics of the suspension play a key impact on the vehicle performance such as vehicle controllability and stability.In this paper,a multi-body kinematical model of a double-wishbone front suspension used in an exploiting truck is established by using the software automatic dynamic analysis of mechanical systems(ADAMS)/CAR.Then the kinematics and compliance simulations are carried out after putting displacement and force constraints on the vehicle wheels respectively and the changes of the vehicle wheels location parameters under these two characteristics are gotten.The study provides reference for the improvement of the front suspension and the vehicle performance.
