Design And Characteristic Analysis Of Hybrid Power Coupling Device

With the world's dwindling oil resources and automobile exhaust pollution of urban air pollution,countries are doing everything possible to reduce vehicle fuel consumption and the development of new energy research,in order to reduce the excessive dependence on oil resources and reduce vehicle exhaust pollution to the environment.In this paper,the hybrid power coupling device is taken as the research object,according to the relevant parameters and dynamic performance requirements of HB6732 light bus in Hebei bus factory,comprehensive research results at home and abroad,a new type of power coupling device is designed and developed,which can be used to realize the coupling of oil and power.First of all,the overall planning of the dynamic coupling device is presented,which includes the matching of the motor parameters,the design of the planetary gear and the structure design of electromagnetic clutch unit.According to the dynamic requirements of HB6732 light bus,the type and power parameters of the motor are determined.Based on the analysis of the performance parameters and characteristics of planetary gear transmission,the transmission type of planetary gear coupler is determined.The calculation results of dynamic indices,calculate the relevant parameters of planetary gear train.According to the functional requirements of the locking mechanism,the structure of the electromagnetic clutch unit is designed.Secondly,the key points of the coupling process are calculated by the equivalent lever method.Based on the speed control,this paper analyzes the process of starting the motor vehicle,the intervention of the engine and the work of the electromagnetic lock control unit.At last,the whole coupling process from start to maximum speed is summarized,the speed change of planetary gear train movement process of components,and the simulation of the planetary gear coupler in ADAMS,use the MATLAB software to handle the simulation results,and the vehicle speed and acceleration curve are obtained.Through the analysis of the velocity and accelerationcurve,the maximum load of the vehicle is obtained,which provides the analysis data for the finite element analysis of the ANSYS Workbench.Finally,the 3D solid model of the coupling device is established by Solidworks,and the finite element analysis is carried out in ANSYS Workbench.In order to ensure the accuracy of analysis results,the hexahedral mesh by using HyperMesh software,and the finite element model into ANSYS Workbench Co simulation.Using ANSYS Workbench static analysis module and Fatigue tool toolbox,the strength,stiffness and reliability analysis of the maximum load of the planetary gear coupling are analyzed,at the same time,the Block Lanczos method is used to analyze the mode of each working state,the natural frequencies and mode shapes of planetary gear couplers are obtained.From the analysis results,we can see that the planetary gear coupler meets the design requirements.
