The suspension characteristics of a 10 ton truck with a highly non-linear leaf spring suspension were investigated. A state-variable linear 5 degree-of-freedom spring mass damper model of the vehicle was created within MATLAB in an attempt to predict the frequency response characteristics of the vehicle. The acceleration transmissibility frequency response characteristics of the truck were also investigated. Results showed that whereas the bounce resonant frequency was quite close to that expected, the wheel-hop resonant frequencies were roughly twice that expected.
