Study of light and heavy-duty vehicle suspension model performance under different road profiles.

Ride comfort and Road holding execution of the vehicle are the most critical factors in the suspension system performance study. Most of the time researchers assume the numerical model of vehicle suspension is a linear and detailed comparative study with the non-linear model that has not been done in previous researches. Hence, the numerical model for both linear and non-linear quarter vehicle suspension is developed in this research work to study the importance of nonlinearity suspension segments. The dynamic outcomes such as sprung and unsprung mass displacement, velocity, acceleration are calculated by conducting the simulation for light-duty and heavy-duty vehicles under sinusoidal and unit step road input based on developed numerical models and program codes. The outcome from this research paper shows that an extensive distinction has been seen in the ride comfort and street holding execution of the linear and non-linear car suspension framework. Simulation results show that there is an increase in ride comfort execution and road holding execution of the vehicle in the event of non-linear suspension than the typical linear suspension. In this way, it tends to get close for a sinusoidal road excitation the non-linear suspension consistently acquires preferred execution over the linear suspension. Considering the nonlinearity suspension segments is more important during modeling and designing of the vehicle suspension system. [ABSTRACT FROM AUTHOR]
