【Abstract】 The features of vibration excitations and all elements in mass and stiffness matrices as well as their correlations for the mounting system of automotive powertrain are analyzed and the theoretical fundamental and importance of elastically uncoupling design for the system are expounded. Some difficulties in elastically uncoupling design of three-point mounting system are pointed out, and a few effective techniques for optimal arrangement of the mounting system to overcome the above-mentioned difficulties are suggested.更多还原
