【Abstract】 Taking the frame of a bus as the object,the finite element model of the frame is established by HyperWorks and its stiffness and modes are analyzed.At the basis of this,with an objective of minimizing the mass,the size optimization of the frame is conducted on the premise that the stiffness and modal performance is not reduced.更多还原
