An Analysis of Heavy Duty Truck Ride

To analyze truck ride comfort, the authors developed a relatively simple simulation model in 16 degree-of-freedom. As a result of studying important truck structural features, such as friction of leaf springs, bending stiffness of a frame, etc., calculation results of a transfer function response analysis agreed fairly well with measured data. As means for ensuring better ride comfort, NISSAN DIESEL developed a floating cab suspension system. To optimize the specification of the system, we utilized this analytical method effectively.
