| Abstract: | The umbrella slot of conocyl SRM grain is a critical position in the grain design process as it is easy to crack under low temperature load.In order to optimize the shape of umbrella slot,parameterized modeling program was designed by PCL(Patran Command Language),the secondary development tool of MSC.Patran,by which the computing result could automatically export according to the import parameters.Integer-coded GA and parameterized modeling method were applied to the shape optimization,with the maximum load... |
