Numerical simulation of vibration performance for nuclear island radioactive boron acid water control valve

On nuclear island radioactive boron acid water control valve vibration characteristics of the process of conducting dynamic analysis of nuclear safety and the important role of the assessment described using finite element analysis product vibration analysis of the practicality of Technology, discussed the use of three-dimensional finite element analysis software-class nuclear safety valve vibration analysis of the basic idea and process. According nuclear island parallel plate sluice valve design data to establish a three-dimensional model using 3-D finite element calculation method, according to a valve assembly, the proper handling of the contact surface and address computation and accuracy of contradictions, valves derived from the natural frequency of the former six bands is an important basis for calculating seismic valves.
