Abstract
Further improvement of durability has been required for timing chain system for automobile use. Development of a technology for predicting timing chain load is indispensable, as is fulfillment of low vibration and low noise requirements. Although software for estimating timing chain load is already available on the market, the analysis method and influences of required parameter are not very clear for users. As described in this paper, a one-dimensional vibration model of a chain system, in which the timing chain is approximated by spring and damper elements, is proposed to contribute to determination of timing chain system specifications as the final target. Furthermore, numerical analyses will be performed of motion equations introduced herein. Obtained chain load will be compared with experimental results for discussion.
