In the beginning of vehicle development, it is difficult to define the concept of engine mounting system. With only the property of vehicle, we have to find the direction of engine mounting system. And it is important to find common mounts for several engine variation in order to reduce the cost and manage mounts efficiently. This paper introduces the software which has developed for engine mounting system analysis. And its function and usefulness are explained in paper. The examples have correlated between the analysis model and real model to raise the accuracy during development of engine mounting system are shown in paper.

Recently active engine mounting system is developed for improvement of vehicle NVH performance which follow the development of high efficient powertrain and lightweight vehicle body. The most important part in the development of active engine mounting system is implementation of optimal engine mounting system to apply active engine mount. In this paper engine mounting systems including active engine mount are considered and their performance is predicted using engine mounting system analysis tool. Then optimal mounting system for active engine mount is proposed.

For development of low fuel consumption vehicle, design of engine can he changed and it brings collateral effect. Abnormal vibration is one of bad effect of high efficiency engine and it can be got over by active engine mount system. For development of active engine mount system, an adequate experimental equipment is required which contain characteristic of real engine movement. To make adequate experimental equipment, regulated force vibrating system including characteristics of vehicle chassis is required.

Engine Mount plays an important role which supports engine, isolates vibration from engine and blocks the vibration from road. Development of engine mount for NVH costs great a deal. So, the cost of development being reduced, the way developed effectively engine mount using DFSS technique is proposed in this paper. CTQ(critical to quality) is vibration and parameter is dynamic stiffness of mounts. The core parameters are selected with TPA(transfer path analysis) technique. It uses design of experiments(DOE) or Taguchi Methods to optimize parameter values and reduce variation. And then, this paper shows the result of improvement for vibration in the developing vehicle.

The vibration of a vehicle, which is caused by and transmitted from the engine, has significant effect on the ride comfort and the dynamic characteristics of the engine mount system have direct influence on the vibration and noise of the vehicle. This paper examines the body shake caused by the engine excitation force on engine key on/off of a medium truck by experiment and simulation. The analysis model consists of the engine, a body including the frame, front and rear suspensions and tires. The force element between the body and the suspension is modeled as a combination of a suspension spring and a damper. The engine shake obtained from the experiment was compared with the result of the computer simulation, and by using the verified computer model, parametric study of the body shake on engine key on/off is performed with changing the stiffness of an engine mount rubber, the engine mount angle, and the position of engine mounts.
