| Abstract:The stress conditon of a certain diesel engine was studied by simulation and experimental methods. The stress distribution of the rocker-arm was obtained through simulation, the results offered references for the paste of strain in the test. A valve train dynamic testing system was built up, and simultaneous measurement of multi-parameter tests was carried out. The experimental results show that the rocker-arm’s stress distribution significantly varied at different areas; the test and simulation results were nearly the same, which provided valuable references for the optimization design of rocker-arms. |
