| The dumper is an efficient large-scale equipment used for dumping and unloading bulk materials such as coal and other bulk materials loaded by gondola wagons.It is widely used in metallurgy,thermal power and port and wharf industries.As a safety part of the pumping station,the fuel tank of the pumping station not only affects the safety of the pumping station Performance,and the quality of the fuel tank is large.When it is turned over,the impact of the oil inside the fuel tank on the tank wall,coupled with the stress concentration during the welding process of the steel structure,will form cracks in the stress concentration location,causing a major accident.Due to the shock of vibration and oil from the oil tank,the partition in the tank is easy to fall off,causing the tank to tear and oil leakage.This topic focuses on the characteristics and load characteristics of the fuel tank structure of the dumper pump station.Use Solid Works to model the fuel tank of the dumper and pumping station,and use ADAMS to simulate the dynamics of the fuel tank of the dumper and pumping station,and obtain different working conditions from the force curve.And on the basis of the four working conditions,the statics analysis of the bracket and the fixed belt seat of the fuel tank is carried out,and the stress and deformation are obtained,which lays the foundation for future structural optimization.The equivalent stress analysis of the bracket is carried out to verify each other with the subsequent optimization.Perform modal frequency analysis and structural design on the base of the dumper and the fuel tank of the pump station.Use the FLUENT software to set the other parameters of the pump station fuel tank unchanged,the five important parameters of the pump station fuel tank head depth,the size of the long and short axis of the tank,the cross-sectional shape of the partition,the number of partitions,and the distance between the partition and the head are five important parameters.The fluid-solid coupling simulation simulation of the model is used to study the influence of a single factor on the stress and deformation of the fuel tank of the pump station.Using the method of orthogonal experiment,explore the influence of the four factors,the depth of the oil tank head of the pumping station,the size of the long and short axis of the tank,the cross-sectional shape of the partition,and the distance between the partition and the head,on the fuel tank at different levels during the fluid-solid coupling process.Preferably the type suitable for the pump station fuel tank.Based on the static analysis of the bracket,it is optimized.Through topology optimization and response surface optimization methods to optimize,the purpose is to reduce the excess of materials,reduce the overall weight,reduce stress and deformation,compare the two optimizations with those before optimization,analyze the value of the optimized results,and compare them with those before optimization.Mutual verification of equivalent stress analysis.In this paper,the finite element simulation and optimization of the structural deformation of the fuel tank of the dumper pumping station provide a reference for lightening the fuel tank of the pumping station and extending its service life. |
