Abstract Based on the functions of CG (centre of gravity) position and inertia moment measurement of passenger vehicle dual-shaft K&C bench and existing separation measure method which are calculated by lever principle and moments of inertia parallel theorem, a correction method of CG position and inertia moment of commercial vehicle cab is developed. This correction method can consider K&C coordinate system changing to vehicle coordinate system and correcting the malposition between the installation position and design position. This method can solve problems shortage of existing separation measure method and correction method and its result is much better to more meet the engineering needs of commercial vehicle cab vibration isolation analysis, was verified through the test of known CG and inertia value calibration block.
