Structural Analysis and Optimization for a Frame-type Cab of a Heavy-duty Truck
The structural analysis of a cab can examine its performances,and then provide a direction for structural optimization.This paper takes a frame-type cab as the research subject,its finite element model and corresponding test scheme are established,and then its torsion stiffness and modal characteristics are analyzed through both simulation and test.Appropriate variables for optimization are screened according to sensitivity analysis.Finally structural optimization for the cab is conducted,so that its torsion stiffness is improved effectively,and simultaneously the structural lightweight design is accomplished on the premise of maintaining the lower modal frequencies on the original level.
