高地隙自走式噴霧機(jī)全工況滑轉(zhuǎn)率控制方法研究
[Abstract]:The high gap self-propelled sprayer belongs to a large, high end agricultural equipment, which can be used for almost all crops and economic crops, especially high straw crops, high efficiency and precision planting, thus greatly reducing the labor intensity of farmers, protecting workers and improving economic benefits to the greatest extent. At present, the high land in China The self-propelled sprayer mainly depends on the high price import, and the performance of the domestic sprayer is difficult to meet the requirements. As one of the main components of the vehicle chassis, the driving system has an important influence on the performance of the whole machine. As an important means to ensure the performance of the whole drive system, the wheel slip rate control system has a direct impact on the system. The efficiency of the sprayer, stability and safety of the driving, and so on. Therefore, this paper studies the technology and methods of the rotation rate control of the high clearance self walking spray locomotive. The specific contents include: (1) through the comparison and analysis of the structure of the 6 kinds of anti-skid driving schemes commonly used in the existing high clearance self walking sprayer, the application model is applied. For the advantages and disadvantages of the control and anti skid control, 2 schemes are proposed for the sliding rate driving control system, which are suitable for small and medium power and high power high gap self walking sprayers. At the same time, a hydraulic principle diagram of the active proportional anti slip control valve (ASC valve) and the bottom disk drive system of the sprayer is designed according to the functional requirements. In theory, a mathematical model of the 4 type of ASC valve based on HIC valve and ASC valve is set up, based on the boundary condition, and the mathematical model of the 4 kinds of spray rate control hydraulic drive system based on the HIC valve and the ASC valve. The simulation analysis of the HIC valve and the ASC valve characteristics is carried out based on the Matlab/Simulink simulation model of the spray machine driving system, and the performance of the ASC valve is simulated and analyzed. The anti slip control effect of the 4 schemes and the energy loss of the antiskid valve are compared and analyzed. (2) based on the unique structure and function characteristics of the high clearance self walking sprayer, a fifteen degree of freedom vehicle dynamic model is set up, including 6 degrees of freedom of the body, the vertical runout freedom of 4 non spring loads, and the free rotation of the 4 wheels. The dynamic model of the vehicle is composed of the body model, the wheel module, the angle calculation module, the suspension system model, the tire model and the driving system model, which can fully reflect the dynamic characteristics of the vehicle in all directions. At the same time, the Matlab/Simul of the high power, small and medium power sprayer is built, respectively, Matlab/Simul. Ink simulation model, and the simulation analysis and real car test research under several typical working conditions. (3) analysis of the cause of the skidding of the sprayer, the basic principle and the anti slip control method. In view of the problem that the wheel wheel center speed of the spray locomotive is not easy to obtain directly, the judging standard of the wheel skidding is formulated. To judge the slip rate, the relative speed ratio difference is used to judge the steering. In view of the problem of getting the wheel deflection angle when the sprayer steering, the scheme of the two wheel and four wheel steering system of the sprayer is designed, and the mathematical model of the full hydraulic steering system is set up. Based on the principle of the ASC valve electric proportion control system, the external input module and the whole vehicle are set up. The dynamics module, the steering system module, the driving system module and the control system module of the sprayer slip rate control system. The PID control, the fuzzy control strategy are formulated respectively, and the anti skid control simulation of the control is carried out with the Matlab/Simulink software. In view of the problem of the throttle loss in the control of the ASC valve, a base is put forward in this paper. The sliding rate control strategy in all working conditions can determine the opening and closing of the ASC valve according to the specific operating conditions and energy consumption comparison and analysis. (4) the anti skid controller is developed. Based on the hardware in the loop simulation technology, the hardware in the skid rate control system of the high clearance self walking spray machine is set up in the loop simulation test platform, and the test of anti skid control is carried out.
