Design Optimization And Simulation Analysis Of Hosting Platform Of The Large Capacity Emergency Uninterrupted Power Supply Vehicle

In order to design a performance-compliant UPS power supply vehicle bearing platform,first of all,the use of traditional design methods,the design of a UPS power supply vehicle used in the hosting platform.Then through simulation by ANSYS to analysis to design a new compliance platform to meet the requirements.The statics analysis of the redesigned bearing platform needs to be combined with the general use scene of the power supply vehicle,so this simulation of four typical working conditions,respectively,when the power supply car to maintain a uniform forward when the full load bending conditions,when the power supply line through the uneven road surface of the full load torsion conditions,when the power supply car in emergency conditions of braking conditions When the power truck encounters an emergency turning condition that requires urgent avoidance.Through the analysis and calculation of the bearing platform under these four working conditions,the stiffness and strength of the bearing platfor m are analyzed and calculated,which is a very important reference to evaluate whether a bearing platform is available,and it is possible to clarify whether the platform meets the predefined conditions and the location of the specific unmet conditions.It is convenient to improve and optimize it later.The hosting platform is the most important part of the power supply vehicle,above which is the equipment,below is the frame.Therefore,when the power truck is driving,the platform will be subjected to a large number of different frequency external excitation,may resonate with the platform itself,affecting the performance of the vehicle.Therefore,it is necessary to obtain the first six order natural frequency and vibration pattern of the bearing platform through modal analysis of the bearing platform.Based on the modal analysis,the harmonic response analysis of the bearing platform is carried out to test the response of the bearing platform when it is subjected to sinusoidal load.Because power trucks are not only on flat roads,they also need to meet the driving requirements of complex roads.Therefore,in the vibration analysis,the general choice of power supply vehicle in the concrete pavement and on the gravel road two conditions,and then for the two conditions of the bearing platform to carry out random vibration analysis.Through random vibration analysis,the stress and deformation of the bearing platform under different pavement conditions can be obtained.According to the simulation results of random vibration,it can be found that when the power supply vehicle is driving,the pavement will give the power supply vehicle a larger random load,which has a greater impact on the bearing platform.In order to achieve the goal of optimizing the bearing platform,the topology optimization method in ANSYS Workbench is adopted,through the calculation and analysis of topology optimization,and according to the actual production situation and cost considerations,the load platform is optimized,and then the static and dynamic analysis,modal analysis,after the optimized bearing platform is carried out,Random vibration analysis and vehicle experiments.The optimized hosting platform still satisfies the conclusion that the performance requirements are use d.By using the finite element analysis method of the bearing platform,the static mechanics and dynamic characteristics of the bearing platform can be calculated and analyzed respectively,and the required results are obtained,which not only provides the theoretical basis of optimization and design for the subsequent bearing platform,but also can be used as a reference for the design of the same type of van.
