Summary:

In this paper, valve spring parameters are optimized based on an iterative logic with constraint on space availability, stress limit, stiffness and natural frequency of the system. The optimized valve spring configuration is used in the push rod type valve train and the valve train dynamics for different engine speed is studied using commercially available multi-body dynamic ADMAS software. The valve train components such as cam, tappet, push rod, rocker arm, valve retainers and valve are modelled as rigid bodies and the valve springs (inner and outer valve springs) are modelled as flexible bodies. Each coil of the springs is modelled as separate flexible body and contact between these coils are established. A comparative valve train dynamics analysis is also carried out with the existing and optimized valve spring combinations. It is observed that valve jump engine speed with respect to optimized valve spring is enhanced to considerable amount when compared to the existing valve spring configuration
