The development of a special garbage truck has important economic significance and application value.The material-lifting mechanism is an important part of garbage collection for garbage trucks.The existing material lifting mechanism has the problems of impact and easy leakage during the discharging process.This subject improved the design of a new type of material lifting mechanism to achieve the smooth operation of garbage bin clamping,lifting and turning,reliable work,and avoid secondary pollution.The research work carried out mainly includes:(1)Three-dimensional digital modeling of the improved lifting mechanism,kinematics simulation analysis using ADAMS,and optimization of the position of the hinge point to improve the smoothness of the lifting process.(2)Establish the rigid-flexible coupling model of the lifting mechanism,use the lifting arm,lifting cylinder and turning cylinder of the lifting mechanism as flexible bodies instead of the original rigid body.Through dynamic simulation analysis of the rigid-flexible coupling model,the main hinge points are obtained To verify whether the design meets the requirements.(3)Design and calculate the electronically controlled hydraulic control system of the lifting mechanism,determine the parameters of the main hydraulic components,establish the hydraulic system model and apply AMESim for simulation,and verify that the simulation results are consistent with the work flow.The PLC is used for integrated control to realize the automatic work of the feeding mechanism of the garbage truck.(4)Trial-manufacture and assemble prototype vehicles of the improved material-lifting mechanism,conduct comprehensive performance tests on the site and road,verify the correctness of the simulation analysis,and provide theoretical and experimental basis for mass production.
