Dynamics simulation of timing chain drive system for diesel engine
To 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.
Methods
2
This 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.
Results
2
The 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.
