Abstract

Abstract

It is of great engineering significance to accurately calculate the local stiffness of typical cylinder and lug connection structures in nuclear power plant reactor system. In this paper, a three-dimensional finite element model of cylinder and lug connection structure is established. The total displacement can be acquired by finite element calculation, and the calculation method is respectively introduced to solve the beam displacement due to concentrated force and torque, which will be used to calculate the final local stiffness of cylinder and lug connection structure. The separate model of cylinder and lug connection structure is established, which is also used to calculate the final local stiffness, and the local stiffness difference is discussed by comparing with the calculation results of whole model. The whole model calculation method is considered to calculate the local stiffness by selecting different boundary planes, and the variation law of local stiffness is obtained. At the same time, the angle of lug is adjusted to calculate and study the influence on local stiffness characteristics. This paper can provide reference for engineering design of cylinder and lug connection structure.
