| Abstract: | By applying the theory of multi-body system dynamics and virtual prototyping technique, the vibration isolation of cab mounts in a commercial vehicle is studied in this paper. Adopting parameterized modeling technique in ADAMS software, a virtual prototype model for a typical commercial vehicle is built and a random vibration analysis is conducted. With the mean square root of cab seat acceleration as evaluation indicator, the parameter matching and design modification on original cab mounts and chassis suspensions are carried out. The effect of vibration isolation in modified cab mounts is markedly improved. |
