| Abstract: | This paper describes the calculation methods of finite element strength for spokes frame casing, which is used in aero-engine by the actions of various complex loads. Three calculation methods are discussed for simplifying the mechanics' and finite element models of the casing. The strength calculations for HP compressor outlet casing of some aero-engines have been done. On the whole these calculated data are in accord with the test results. |
