Modal analysis of compound grinder for grinding end face and inner hole

摘要

According to the structure of compound grinder for grinding end face and inner hole of tappet body, this paper established the finite element (FE) model and presented the modal analysis of the compound grinder and its components by means of three-dimensional software and FE method. The first four natural frequencies and modal shapes of the compound grinder were given. As a result, the weaknesses of the compound grinder were determined and it offered the basis for improving dynamic property of the compound grinder.
