[Abstract]:In this paper, the advantages and disadvantages of different types of reducer energy recovery devices (piezoelectric, mechanical, electromagnetic and hydraulic) are compared. The hydraulic fluid is used as the energy recovery medium of the reducer, according to the speed range of the vehicle passing through the reducer. This paper presents a design scheme of hydraulic vibration energy recovery device for road speed belt which combines split-type power generation (the speed range of vehicle passing through reducer is in 10~20km/h) and continuous power generation (speed range of vehicle passing through reducer is in 20~30km/h). Based on the vehicle-reducer model, the vibration acceleration of the vehicle body and wheel under the reducer excitation is solved, and the influence of the width and height of the reducer on the dynamic performance of the vehicle is analyzed. Based on this, the geometric profile of the reducer applied to the hydraulic vibration energy recovery device of the road speed reducer is determined, and the coupling dynamic model of the vehicle-reduced-hydraulic transducer is established. The characteristics of coupling vibration between hydraulic reducer vibration energy recovery device and vehicle are analyzed, and the mathematical model of hydraulic system of reducer continuous power generation module is established by using transfer function method. The mathematical model of hydraulic system of reducer assembly generating module is established by using power bond graph method. Based on the coupling characteristics of vehicle-reducer and hydraulic transducer under the condition of relatively high speed vehicle (20~30km/h), the joint simulation of Matlab/Simulink and AMESim is established to study the continuous power generation module of deceleration belt. Based on the coupling characteristics of vehicle-reduced-hydraulic transducer at low speed vehicle (10~20km/h), the joint simulation of ADAMS and AMESim is established to study the sub-generation module of reducer. According to the simulation results, the parameters of the vibration energy recovery system of the reducer are matched, and the influence of the design parameters of the hydraulic system on the energy-saving characteristics of the hydraulic vibration energy recovery system of the road speed reducer is studied. With the aim of maximizing the vibration energy of the speed reducer, the working parameters and the type of components of hydraulic system are determined. Based on 3D virtual modeling, the vibration energy recovery device of reducer is designed. The assembly structure and the space arrangement of the device on the road are integrated, and the design and manufacture of the test bench are carried out. Finally, a bench test is carried out for the designed prototype. Firstly, the hydraulic system oil circuit problem is analyzed and improved through bench test, and then the simulation test is carried out on the improved bench to test the power generation capacity of the reducer.
