| Abstract: | A parametric 3-D FEM program for piston thermal load analysis and its data interface program were developed with COSMOS/M parametric command language and Delphi object oriented language. The whole program could overcome difficulties related with calculating the changes of temperature field of piston in varied structures and boundary conditions due to its full parametric FEM analysis model and convenient data input interface program with verification function. The developed programs were used to calculate the piston thermal fields of 4105 and 490 diesel engines in steady state, the influence of structure size and temperature of cooling water were also discussed. The solutions are of great value to the optimum design for piston structure. |
