| Summary: | ObjectiveTo validate the correctness and rationality of a diesel engine timing chain drive system, as well as to investigate the effects of wear elongation over the timing chain's lifecycle on the dynamic characteristics of the timing chain drive system, it is necessary to conduct a dynamic simulation analysis of the timing chain drive system.MethodsThis paper developed a multi-body dynamics model based on the multi-body dynamics simulation software RecurDyn. The dynamic characteristics of the timing chain drive system were investigated under various speed conditions. By constructing a dynamic model with 0.3% chain wear elongation, the dynamic characteristics analysis of the timing chain drive system under extreme operating conditions with chain wear elongation reaching its limit was accomplished.ResultsThe results indicate that the analysis of dynamic characteristics such as chain tension and transmission error during the life cycle of the timing chain drive system meets the requirements, verifying the reliability of the timing chain drive system throughout its service life and the stability of the system under extreme conditions. The RecurDyn-based multibody dynamics simulation methodology for diesel engine timing chain system presented in this paper provides an effective and reliable research approach for dynamic characteristic analysis and performance evaluation of timing chain drive system. |
