Research On Management Strategy Of Trailer Braking Energy Recovery And Hybrid Drive Technology

With the development of the economy over time,industrial production has also developed rapidly,and transportation has also played a vital role in various fields.At the same time,energy and environmental problems have become prominent.The rapid development of the transportation industry has led to energy With increasing pressure and increasing environmental pollution,the issue of energy conservation and environmental protection has attracted more and more attention from the world.In order to explore and research new energy-saving technologies,hybrid power technology is one of the best choices at present,so hybrid power provides a powerful reference in the transportation industry.This article takes a certain type of semi-trailer as the research object,analyzes and studies the main components of the hydraulic brake energy recovery system on the braking energy recovery efficiency,braking force control distribution strategy and the semi-trailer under different intensity braking conditions.The impact of energy recovery efficiency.Then the parameters of the components in the hydraulic braking energy system are calculated and the models are selected;then different braking force control strategies are formulated;finally,the model of the whole vehicle and the hydraulic braking energy recovery system is established for research and analysis.The paper has mainly made progress in the following aspects:(1)Firstly,the concept,principle,classification and research status of hybrid power are introduced.At the same time,the current application of hybrid vehicles and the research status at home and abroad are explained.Finally,the research content and significance of this article are put forward.(2)Analyze and study the principles of hybrid vehicles,study the force status and theoretical analysis of the vehicle during braking and driving,study and analyze the influence of the main components of the hydraulic brake energy recovery system on the energy recovery efficiency of the vehicle during the braking process,And to calculate and analyze the parameters of the main components in the hydraulic brake system and select the appropriate model.(3)Analyze and study the previous methods and strategies of braking force control,and formulate a braking force control strategy suitable for semi-trailers.First study the braking force distribution of the vehicle during braking.First,study and analyze the braking force distribution of the two-axle vehicle during braking.Then analyze and compare the braking force distribution of the three-axle vehicle based on the two-axle vehicle.The control strategy is formulated to be suitable for the control strategy of semi-trailer under different intensity conditions.(4)The simulation analysis of the hybrid semi-trailer is carried out through the AMESim software,including the modeling of the parallel hydraulic braking energy recovery system,the modeling of the braking force control strategy and the modeling of the semi-trailer,and then the accumulator volume and precharge pressure are studied.As well as the influence of the change of the pump/motor displacement of the reversible element on the energy recovery efficiency of the vehicle,the braking simulation analysis of the impact of the energy recovery efficiency of the vehicle under different intensity conditions,the auxiliary drive of the semi-trailer in the hydraulic braking energy recovery system It improves the driving performance of the semi-trailer on a slope with a slope of6°,increases the driving distance and speed of the semi-trailer,improves fuel efficiency,and reduces economic costs.
