The safety and comfort of the truck cab, as driver’s location, are significant to the driver, and the white body of the truck cab is an important part of the truck, whose modal and stiffness are directly impact its safety and comfort. Moreover, its modal and stiffness are the key factors that affect the performance of the car, which are also the important indicators that evaluate the ability of preventing fatigue failure and resisting deformation. In order to study whether the modal and stiffness of a truck cab can meet the working requirements, the white body of a truck cab was taken as the research object, and the finite element method (FEM) was chosen to study the modal and stiffness in this paper. The finite element model of the white body of this truck cab was established. The natural frequency and vibration model of white body were obtained by modal analysis. And the lowest frequency of the white body was 22.8Hz, obtained by modal analysis. After that, the modal performance has then been analyzed by comparing with the excitation frequency of pavement and with the excitation frequency of engine. The result shows that the natural frequency of the white body avoids the resonance frequency. Further, the bending stiffness and torsional stiffness of the white body were calculated. The results show that the bending stiffness and torsional stiffness are enough to preventing large deformation under normal working conditions. The above results show that this white body can basically meet the requirements of work.
