The regenerative braking energy recovery system of the rear wheel parallel drive hybrid mining vehicle is studied in this paper.The current problem that restricts the development of mining vehicles is that energy consumption is large and energy is seriously wasted,and regenerative braking energy recovery is one of the feasible methods to solve the above problems.The rear-wheel parallel drive hybrid mining truck has more complex structure and high-efficiency performance than the traditional mechanically driven mining vehicle.It can not only provide large torque to cope with complicated mine road conditions,but also recover the braking process.energy.Hybrid mining vehicle regenerative braking energy recovery system requires small storage space,high energy density and no pollution.Therefore,the battery is selected as the storage component of the regenerative braking energy recovery system,so that the utilization efficiency of the recovered mining vehicle can be recovered and effectively improve.When designing the regenerative braking energy recovery system of the hybrid mining vehicle,the distribution coefficient of the regenerative braking force and the mechanical braking force should be reasonably coordinated to ensure the safety and stability of the hybrid mining vehicle brake,and at the same time increase the braking as much as possible.Energy recovery efficiency.In this paper,the TR50 of the parallel-type hybrid mining truck is the research object.Through the theoretical analysis and the original model,the regenerative braking control strategy of the hybrid mining vehicle is developed,and then the regeneration braking recovery system is built by ADVISOR software.Modal and simulation analysis to verify the effectiveness of the regenerative braking control strategy.Firstly,the main factors affecting the energy recovery efficiency of regenerative braking are analyzed by theoretical research methods.The key components selection and characteristics analysis of the system are analyzed,and the braking process dynamicsanalysis of the vehicle is based on the braking force distribution of traditional mining vehicles.The method and its own structural characteristics,under the premise of meeting the ECE brake regulations,develop a regenerative braking control strategy based on braking strength.Then,in the software ADVISOR,through the secondary development to build the various modules of the hybrid mining vehicle,establish a simulation platform that conforms to the rear-drive vehicle,and embed the developed regenerative braking control strategy into the regenerative braking system,in ADVISOR software.Establish a simulation model of the regenerative braking system of the hybrid mining vehicle.Finally,the typical mine conditions in China are selected for simulation analysis.The simulation analysis is carried out under different braking strengths.The braking energy recovery rate is as high as 65.01% under light braking intensity,which is 23.66% higher than the self-contained control strategy in ADVISOR.When the motor braking power is approximately 174 kw,the motor recovery efficiency reaches a maximum of 31.89%.This paper provides effective assistance for the development of products in the mining vehicle market,provides effective solutions for solving energy waste and reducing the environmental environment,and provides theoretical support for the follow-up study of the regenerative braking energy system of hybrid mining vehicles.
