Collaborative model analysis on ride comfort and handling stability

Abstract

For considering the connection and mutual influences between ride comfort and handing stability of a vehicle, a collaborative study on the two performances is carried out in the paper. Firstly based on the UniTire model and combined with filtered white noise models for front and real road excitations, 4-DOF plane model for ride comfort and 2-DOF plane model for handling stability, a collaborative model for ride comfort and handing stability is built by adopting state equations, and a collaborative simulation algorithm for them is also proposed. Then, a collaborative simulation on the ride comfort and handing stability of a vehicle under common road grade and speed conditions is conducted. The results show that the ride comfort and handling stability of a vehicle can be simulated simultaneously by using the collaborative model. The handling stability parameters simulated with the linear UniTire model are larger than those simulated with the nonlinear UniTire model, indicating that it is obviously conservative to study vehicle handling stability with the linear UniTire model.

Research on Road Roughness Based on NARX Neural Network

“…Many researchers have focused on improving the comfort and vibrational response of the vehicle. For example, Liu and Cui [19] proposed a collaborative simulation algorithm for the performances between ride comfort and handling stability of a vehicle considering the connection and mutual influences. Jiang et al [20] investigated the problem of interactive road roughness identification and proposed a novel inverse algorithm based on the knowledge of a vehicle dynamic characteristics and dynamic responses.…”
