Abstract: A model of a cab-operator and an isolating mount system is created and analysed. The method to calculate a system's natural frequency and kinetic energy percentage distribution of mode is presented. The optimised design to achieve the desired natural frequency range and minimise the motion coupling at each mode is introduced. The results of a case study demonstrate that suitable mount locations and rubber mount stiffness create the required natural frequency and lowest mode coupling. The disturbance or excitation from one motion to the others is minimised so that the vibration isolation performance will be greatly enhanced.

Keywords: cab vibrationn; vibration isolation; mounting; principal axes; natural frequency; percentage kinetic energy distribution; optimisation; vehicle design; vehicle vibration; motion coupling; mount locations; rubber mount stiffness.
