The Study Of Power Match And Regulation Of Velocity Of Device Used For Power Synthesis And Switch Used On HEV

Hybrid ElectricVehicle (HEV) to be able to alleviate the energy tense pressure and the reduced pollution most feasible method as the present automobile domain, already becomes the present world automobile domain research the hot spot.Mixes the electric automobile in to act the role by the traditional fuel automobile to in the fuel cell automobile transformation which links the preceding with the following.The power synthesizes and cuts the installment to take the mix electric automobile the important part, it is uses above the mix power electric automobile uses for to realize the energy entire and with the assignment mechanism, the mix power automobile has at least two power supplies, mixes the power electric automobile to have an engine and an electric motor generally provides the power, this equipment mainly is in order to realize simultaneously works when two power supplies, dynamic coupling and assignment question. Can realize the complex working condition demand by the planetary gears dynamic coupling, therefore could be the next research and the development key point. This article studies the power synthesizes and cuts the installment the core is a set of planet gear system, it can realize the different input rotational speed and the power synthesis, has the reliable energy divergence, the energy flux direction change moreover the structure is compact, facilitates the control, moreover effective, reliable, it with the traditional power drive technology close union, can support many kinds of working pattern.This article unifies the theoretical model, carries on the structure size the optimized computation, obtains the best model size design parameter; Meanwhile take the UG software as the platform, the build power synthesizes and cuts the installment the model; Passes UG, ADAMS to carry on the kinematics and dynamics simulation analysis; Synthesizes and cuts the installment to input the output under the different operating mode to the power the transmission ratio and the power match relations conducts the research.Through synthesizes and cuts the installment transmission ratio and the power match rule research to the power, this article realized the match essence was optimizes the question, in the match category which this article proposed, although had the product to solve properly, but sought the better design result comprehensively from the optimized angle, also had the big potential, was worth deepening the research and the application. Has in the very many match category content, may establish the mathematical model, but some contents difficulty with establish, needs to consider the experience experiments and profits from the case to seek the satisfactory solution; In addition, the optimal solution often is the ideal result, in the practical application possible structure not easy to realize, sometimes the suboptimal solution can be better. Also realized, the subsystem optimization not necessarily is the overall system optimization, must guarantee main may sacrifice the secondary target to coordinate suitably. The system match optimization has the strategy which it cannot be substituted, but in design, if and unions and so on finite element simulation and even hypothesized technology, can the better display design technology integrated superiority.
