Recently, for weight and cost reduction the new mount and sub-frame system has been ongoing research. As a result, through the application of H-type sub-frame, a pendulum-type engine mounting system with engine, transmission, and roll mount have been proposed. However, the freedom of the design has been largely limited to obtain the optimal performance between the control of powertrain behavior and the vibration isolation influencing the durability of the mount and NVH quality simultaneously. So, 4 different type of roll rod was taken into account and validated experimentally in this study under the maintenance of same platform, the contribution of load sharing and NVH performance was to optimize. It is shown that CTR roll rod is more effective than any other type to compromise the efficiency between durability and NVH.
