TAILIEUCHUNG - Influence of the engine mounting system on the automotive ride comfort

The the parameters of engine mount system such as stiffness and damping coefficients are analyzed respectively according to the international standard ISO 2631-1(1997-E) for the assessment of the impact of noise and vibration to human health. The results show that the damping coefficient of engine mount system has the greatest influence on automotive ride comfort when engine operates at road surface conditions in Viet Nam. This study can provide a theoretical basis for the semi-active mounting system for engine. | Lê Văn Quỳnh và Đtg Tạp chí KHOA HỌC & CÔNG NGHỆ 139(09): 25 - 30 INFLUENCE OF THE ENGINE MOUNTING SYSTEM ON THE AUTOMOTIVE RIDE COMFORT Le Van Quynh*, Hoang Anh Tan, Nguyen Khac Minh College of Technology - TNU SUMMARY Nowadays, automotive ride comfort is one of the most important performances of automobile, the research of automotive ride comfort is getting more and more important. The aim of this study is to evaluate the influence of the parameters of engine mounting system on automotive ride comfort. To achieve this goal, a 3-D vibration model for automobile with 10 DOF is established and Matlab/Simulink is used to simulate and calculate the impact factor. The the parameters of engine mount system such as stiffness and damping coefficients are analyzed respectively according to the international standard ISO 2631-1(1997-E) for the assessment of the impact of noise and vibration to human health. The results show that the damping coefficient of engine mount system has the greatest influence on automotive ride comfort when engine operates at road surface conditions in Viet Nam. This study can provide a theoretical basis for the semi-active mounting system for engine. Keywords: engine mounting system, vibration model, stiffness, damping, ride comfort INTRODUCTION* Engine mount is purposed to control an excessive motion generated from powertrain system and to isolate vibration and noise to be transmitted to main system. As vibration design of engine mount is one of the main items on the phase of vehicle development, the design should be optimized considering various design variables and uncertainties. In recent years, in research on engine mount system, there have been a lot of papers to mention aspects such as application of ANSYS, software. etc for the design of engine mount system with the source of excitation by itself[3-5]. The torque roll axis for a mounting system with nonproportional damping (under oscillating torque excitation) is indeed .
