| Abstract: | Taking the Thermal Power Engine as research object, simulation research on piston-linkage mechanism by applying multi-body system dynamics is conducted. Based on the dynamics analysis software ADAMS and finite element analysis software ANSYS, the linkage flexibility in the working by dynamics simulation is influenced, then calculation and analysis of dynamic stress distribution on linkage are carried out by utilizing FEA method. This makes mechanism service evaluation during structural design stage possible... |
