A method for determining frequency response function and road spectrum iteration steps of road simulation experiment were given and discussed in this study. Taking one Hydraulic Engine Mount (HEM) in a car as study example, and the road spectrum exerted on the HEM was acquisied in a proving ground. The road spectrum was reconstructed with remote parameter control technology, and the results show that the reconstructed load agrees well with the original one. Also, the method for determining the load block sequence was given and discussed. The durability experiment for an HEM was carried out with MTS 831 test rig using the methods presented in this paper. It’s shown that the methods are effective in doing durability experiment for a mount.
