Abstract
White body finite element model of a light-truck cab is established, with which numerical and experimental modal calculations and analysis are conducted. Based on modal matching principle, a dynamic characteristics analysis is performed, and on the same time, the cab structure optimization is carried out based on the modal first frequency sensitivity analysis. By the structure optimization, the first torsion frequency of the cab is reduced, and the difference between the first torsion frequency and the excitation frequency with the engine idling is increased. To some extent the purpose of reducing vibration and noise is achieved.
