Structural Optimization Design of Large Hydraulic Damper
By using the resistance of hydraulic oil,the kinetic energy caused by vibration or impact can be consumed by hydraulic damper,so as to protect the equipment from vibration damage.So hydraulic damper is widely used in nuclear power plants as an important guarantee for safe operation.Firstly,in order to ensure that the designed damper can meet the requirements,the static analysis is carried out by using the finite element method and the problems existing in the preliminary design are determined.Then,taking stiffness and strength as the main assessment indicators,the relevant influencing factors are analyzed.On this ba-sis,the relevant parameters of the cylinder block,cylinder head,piston,piston rod and other parts of the damper are optimized.Finally,the static test is carried out.The test results show that the stiffness and strength of the optimized damper can meet the working requirements,and the optimization method is feasible and effective.
