Dynamic Stress Analysis of Suspension Control Arm of a Multi-axle Off-road Vehicle

摘要

Rigid-elastic coupling dynamic model of multi-axle off-road vehicle including flexible front suspension control arms were established based on FEA component model synthesis method and rigid-elastic coupling dynamic theory.Dynamic structure strength of front control arms were validated via dynamic simulation of multi-axle off-road vehicle running on typical undulant and random road surfaces,. The method provides credibility technical support for sub-structure dynamic strength analysis in systematic level analytical approach.
