Sensitivity analysis and optimization for city bus body

QU Xiao-bin,HE Zhi-gang,ZHANG Min-zhong,YU Cheng-xiang(Jiangsu University,Zhenjiang 212013,China)  
The finite element analysis model for the city bus body skeleton is built.The sensitivity of the overall body torsional stiffness and body's first-order natural frequency,which are constitutive parts of body frame,are analyzed respectively,using ANSYS.Choosing design variable due to the sensitivity analysis result,using the body's torsion stiffness and first-order natural frequency as the state variable,and using the body's gross mass as the objective function,the body's structure is optimized.
