The optimization of a motor drive system of the battery electric vehicle (BEV) is a tradeoff among vehicle performance requirements, system efficiency and cost. In this paper, a drive system with the downsized buck-boost converter is proposed to deco

This paper focuses on a physics-based model of a chain CVT. The study starts from kinematics of an infinitely small chain segment, and then investigates the fundamental dynamics of the chain segment. A speed-dependent continuous friction model is emp

An analytical formulation of the brake judder problem caused by disc thickness variation is described by using a simplified source—path—receiver model. Eigenvalue analysis is first conducted to determine the transfer mechanism from the brake sour

The forced vibration response of a single degree of freedom torsional system with Coulomb friction, under a periodically varying normal load, is studied. First, an enhanced multi-term harmonic balance method is developed to calculate nonlinear respon

In this study a large knowledge base is first established through numerous designs of experiments on beam elements, based on a validated finite element model of a reference vehicle body-in-white. Then a recurrent artificial neural network is applied

A family of isolated sub-harmonic branches in nonlinear frequency response of piecewise linear system is examined in this paper. Given their peculiarity, they could be easily overlooked in frequency response studies in numerical integration or labora
