Abstract
There is the possibility of decoupler’s impact noise in hydraulic engine mount (HEM) with a free decoupler, but there is little research on this aspect. As for how to solve the problem of decoupler’s impact noise, most of the papers are only improved through trial and error. This article uses three HEMs with different decoupler plates and cages as the research object for the experiment. First, calculate the contact force between the decoupler plate and cage of the HEM through the finite element method, to determine whether the decoupler’s impact noise problem will occur. Then design the bench test of the abnormal noise of the HEMs to verify the conclusion obtained by the calculation of the contact force. Next, deduce the relationship between the transmitted force at the chassis side of the HEM and the impact force of the decoupler, and propose a test method for evaluating the decoupler’s impact noise based on the transmitted force at the chassis side of the HEM. Finally, summarize the structural design experience of decoupler and cage.
