[Abstract]:Self-propelled shearing platform is a widely used aerial engineering vehicle. Its main function is to carry out engineering work by elevating operators and tools or goods of a certain weight to a certain height by means of the shear platform mechanism. A new type of electric self-propelled shearing high altitude platform with variable frequency hydraulic speed regulation technology has become a new developing direction because of its advantages of clean and environmental protection, good energy saving effect, convenient control, quiet and no noise, high reliability and so on. This paper relies on the independent development project of a new type of electric self-propelled shearing platform in a certain enterprise. Based on the computer simulation and virtual prototyping technology, the electromechanical hydraulic system of the electric self-propelled high altitude platform is modeled and simulated. The main contents of this paper are as follows: Firstly, the paper analyzes the key technology of variable frequency hydraulic speed regulation technology, I. E. vector control of asynchronous motor, and builds a frequency vector control system of frequency vector control of asynchronous motor. Based on the computer simulation technology, the modeling and simulation experiments of the speed regulating system are carried out by using the Simulink simulation software and the SimPowerSystems simulation toolbox. Secondly, the mechanical dynamics simulation model of a new type of electric self-propelled high altitude platform is established by using SimMechanics simulation toolbox, taking the shear fork platform mechanism of a new type of electric self-propelled high altitude working platform as the research object. The displacement, velocity and acceleration of the platform at any time during the hoisting process and the stress curve of the lifting cylinder are obtained by simulation. Finally, the hydraulic system simulation model is established by using the SimHydraulics simulation toolbox after the proper simplification of the hydraulic system. The simulation calculation and analysis are carried out, and the joint modeling and simulation of the electro-hydraulic multi-domain forehead physical system of the lifting system are realized. The results provide a theoretical basis and a virtual prototype design method for the development and design of a new type of electric self-propelled aerial platform.
