Due to the recent trend in auto industry to opt for higher power engines, causes increase in vibrations levels in the passenger’s compartment. This requires a better and comprehensive model to analyze vibrations from engine to seat and steering wheel much before the proto stage of development in the design stage itself.

For this purpose, modelling is done in ADAMS multi dynamics and assuming the 16 degrees of freedom of the vehicle. Further, a crank drive model is developed to simulate engine excitation forces comprising unbalanced inertia forces and torque fluctuations and their effects seat rail and steering wheel vibration is derived.

This tool is an attempt to predict such vibrations caused and assist in design enhancement and streamline the procedure.
