Modeling and Simulation of Stress and Strain of Chassis Structure for Wheeled Robot

Abstract

The three-dimensional solid model of the chassis which is the support structure for the wheeled robot's load and power parts is established. Based on the theory of elasticity, the relation equations of the three direction stress and strain of the chassis structure are given. The calculation analysis and simulation are completed by the finite element method, and the structural stress and strain of the chassis under loads and driving forces are obtained. Through simulating and analyzing the stress, strain and deformation values and distribution on the chassis structure, it makes a basis for the design and research of the chassis with light weighted and appropriate stress and deformation.
