Study On The Maximum Stress Distribution Research Of Branch Pipe In Hydroelectric Power Station Based On Ansys Finite Element Method

This article carry on the computation of the branch pipe by the ANSYS finite element method. In the process of computation analysis it is with the aid-of ANSYS in the parametrization language APDL superiority. It has studied relational function between the hemmed branch pipe branch angular variation and the maximum stress. This will provide variable selection for the engineering designers personnel who have the reference in the hydroelectric power station branch pipe design. The results of research show that the maximum stress of branch pipe increases along with the branch angle reduces. The more smaller the branch angle is,the more quicker the speed reduces. The curve of projects beta-sigma(max) is the function fitting, we can get the results that the function of beta-sigma(max) is close to 3 times multinomial relation according to the datas distributed situation by 1, 2, 3, 4 times multinomials.
