Analysis of a Passenger Car Equipped with an Inertial Track Hydraulic Engine Mounts
摘要
This study investigates the ride comfort performance of a passenger car equipped with inertial track hydraulic engine mounts (HEMs). A full-vehicle nonlinear dynamic (VND) model is developed, incorporating the fluid-structure interaction and inertia track characteristics of the HEMs. The ride comfort performance of the HEM with an inertial track is analyzed and compared with that of a traditional rubber engine mount (REM) under low-frequency excitation conditions, in accordance with ISO 2631. The obtained results reveal that the HEM with an inertial track significantly enhances vehicle ride comfort in the low-frequency range compared to traditional REM. The proposed model provides a theoretical foundation for optimizing engine mount designs in modern passenger vehicles.
