Ride comfort of heavy vehicles based on key response characteristics of multibody dynamics

Abstract

To effectively improve the ride comfort of heavy-duty trucks, and relieve the driver's fatigue and ensure the integrity of the cargo. In this study, first, according to the requirements of GB/T 7031-2005/ISO 8608, the random sine wave superposition method is used to determine the random excitation of a road surface and establish an FRC tyre model based on the elastic roller theory. Second, the Jiefang-6P truck is considered as an example to establish the linear model of heavy-duty trucks, conducting virtual experiments by establishing vehicle–tyre–road closed-loop system. Finally, orthogonal tests with the control parameters as variables are designed to determine the optimal combination of control parameters for best smooth driving. Thereafter, range analysis is used to determine the degree of impact of each control parameter. The effects rules of load, vehicle speed, tyre stiffness and tyre damping on ride comfort are obtained, and the results show that the best ride comfort can be obtained when the tyre stiffness is 60,000 N/m and the tyre damping is about 600 N s/m, and the tyre stiffness has the highest influence on the ride comfort.
