SENSITIVITY ANALYSIS AND OPTIMIZATION FOR LIGHT-BUS BODY STIFFNESS

HU Zhiyuan 1 PU Gengqiang 1 GAO Yunkai 2 (1. School of Mechanical Engineering, Shanghai Jiaotong University, Shanghai 200030, China) (2. School of Automotive Engineering, Jilin University, Changchun 130025, China)  
Structure analysis of light bus body usually just lays particular stress on intensity index and the experimental result of structure intensity is the key index of equipment registration in China. But, the body's structure stiffness also should be one of the key indexes. And, when the body's structure is design under stiffness criterion, it can satisfy the intensity criterion very well at the same time. The body's stiffness includes flexural stiffness and torsional stiffness. The flexural stiffness can be described as the body's deflection, under the plumb load, and the torsional stiffness can be described as the body's torsion angel, under the torsion load. A FEM model for stiffness analysis of a light bus body, which is made in China, is established in this paper. The FEM model's boundary condition--the supporting simulation of leaf spring, and analysis load--how to distribution the load to the FEM model are discussed too. Then, the FEM model is validated by experimental result. Moreover, by identifying the design variable, state variable, and the objective function of the model, the parts' sensitivity of body's flexural stiffness and torsional stiffness, which are constitutive parts of body frame or chassis, are analyzed respectively, using ANSYS. Choosing design variable due to the sensitivity analysis result, using the body's gross mass and the maximum stress of the parts as the state variable, and using the body's flexural stiffness and torsional stiffness as the objective function, the body's flexural stiffness and torsional stiffness are optimized.
