[Abstract]:Multifunctional working machine is a new type of agricultural machinery. The driving mode of walking system directly affects the working performance and running cost of the whole machine. At present, the traditional mechanical transmission is used in the walking system of the multifunctional machine in our country, and its structure is complex. With the rapid development of hydraulic drive technology, more and more agricultural machinery walking system began to use hydraulic drive, its structure is simple, speed regulation range is large, operation is convenient, work is stable and reliable, It has the advantages of reliable driving performance and operation performance. In this paper, a multifunctional operating machine is taken as the research object. In order to improve its working efficiency and maneuverability, the traveling system is designed and studied. On the basis of four driving modes of electric drive, hydraulic drive and hydraulic drive, the hydraulic transmission is used to replace the original mechanical drive in the walking system of the multifunctional working machine, and the specific hydraulic circuit and speed regulation scheme are discussed. A novel hydraulic drive system of multifunctional operating machine is designed, and the whole structure and arrangement of the hydraulic drive system of multifunctional working machine are determined, and the working process is analyzed. By analyzing the dynamics and kinematics of the multifunctional machine, the specific parameters of the hydraulic drive system are designed and matched, and the system pressure, the specific performance parameters of the engine, the hydraulic pump and the hydraulic motor are determined, and the relevant checking is carried out. The dynamic characteristics of hydraulic pump and hydraulic motor are analyzed, the mathematical model of variable pump, variable motor and the equivalent load of hydraulic drive system are established, based on AMEsim software, the dynamic characteristics of hydraulic pump and hydraulic motor are analyzed, and the mathematical model of variable pump and variable motor is established. The hydraulic driving system model of the multifunctional operating machine is established. The response characteristics of the hydraulic drive system under the conditions of the starting condition, the stopping condition, the front and rear power simultaneously working of the multifunctional operating machine are simulated and analyzed, respectively. The performance of the selected hydraulic system can meet the requirements of field operation. In this paper, the hydraulic transmission is applied to the walking system of the multifunctional working machine, and the hydraulic drive system is designed and matched. The specific model analysis of the selected hydraulic pump and motor is carried out, and the modeling and simulation of the hydraulic drive system of the multifunctional working machine based on AMEsim are carried out, and the stability and rationality of the hydraulic system are analyzed.
