Abstract

In this study, the performance of the straight-drawn elevator under various working conditions was analyzed by simulation software in the complex environment in the reactor vessel to optimize the design and determine the reasonable operating parameters. Firstly, the multibody dynamics simulation of rigid-flex coupling is carried out during the operation process of the hoist, and the conditions that may affect the operation of the elevators are analyzed, and the influencing factors are analyzed. Secondly, the solid mechanics analysis and modal analysis of the special working conditions that may occur are carried out, and the operating parameters of the elevators are recommended accordingly; Finally, based on the above analysis results, the structure of the elevators is optimized and verified. The research results show that under the material exchange condition, the hanging barrel will have a certain offset and vibration during the expansion and telescopic process of the cantilever of the hoist, and the lifting opportunity will have a certain deformation under special working conditions. By optimizing the structure and limiting the operating conditions, the deformation and vibration can be effectively reduced, and the normal material change of the elevators can be guaranteed.
