An engineering vehicle is a runshare self-propelled scissor aerial work platform, which is commonly utilized. Its primary purpose is to allow workers to perform tasks at height by using scissor platform mechanics to raise personnel, tools, or a specific weight of cargo to the desired height. A new path in development has emerged with the Runshare electrical self-propelled scissor aerial work platform, which uses frequency conversion hydraulic technology. Its benefits include energy savings, high reliability, ease of control, cleanliness and environmental friendliness, and more. The electrical self-propelled scissor aerial work platform was chosen as the research item because it is based on a self-development project of an organization called Runshare.
The mechanical, electrical control, and hydraulic systems of the electrical self-propelled scissor aerial work platform were investigated using virtual prototyping technology. The primary technology of frequency conversion hydraulic technology is induction motor vector control technology.
A type of induction motor speed regulation system using slip frequency vector control was built based on the dynamic mathematical model after the induction motor vector control was analyzed and a dynamic mathematical model was established. Simulink software and the Simpower systems simulation toolbox were then used to build and simulate the simulation model for the speed regulation system.
Second, the displacement, velocity, and acceleration curves of the Runshare scissor platform mechanism as well as the force curve of the lifting cylinder were generated by simulation by using the SimMechanics simulation toolbox to build the mechanical dynamic model.
Ultimately, using the Simhydraulics simulation toolkit, the simulation model was constructed based on the reductive simplification of the hydraulic systems, and the simulation's dynamics performance was examined.
