The Design And Simulation Of The Suspension System Of100t Hydraulic Self-propelled Transporter

Hydraulic self-propelled transporter is a special transporter of transporting largecomponents, widely used in ship section parts and industrial host equipment of majoritems,which is a kind product of integrating "machine and electricity and hydraulicsystem". Suspension system is an important part of the transporter, which plays a vitalrole on the bearing performance of the transporter. The synchronization performance ofthe suspension system directly affects the use safety of the vehicle, in the process oflifting, the suspension systems should have a good coordination, in the event of a partialload or interference,which can adjust quickly and ensure the safety of objects. Therefore,the design and simulation research of the mechanical structure, hydraulic drive andelectrical control system of the suspension system has a very important value.The paper studies on100t hydraulic self-propelled transporter,which is producedby jiangsu hai peng special vehicle co., LTD. First to study the mechanical structure of thetransporter,aim to the car lifting process,a dynamics simulation is conducted in themultibody dynamics software ADAMS.Then, on the designed suspension hydraulicsystem, components selection and building the mathematical modeling are proceeding.And hydraulic system loop is established by the simulation software AMESim, andapplied the master-slave synchronization control strategy in the hydraulic system model,asimulation study on the hydraulic system of transporter is made.Due to the conventional PID control is unable to get ideal control requirements, andaccording to the actual operation,the paper adopted two kinds of intelligent controlalgorithm, the fuzzy adaptive PID control and fuzzy immune PID control, the paper usesthe simulation software MATLAB to design the fuzzy PID adaptive controller and fuzzyimmune PID controller, and conducts a simulation research on suspension system of100t hydraulic self-propelled transporter.Finally through the simulation software interface module between the mechanicalstructure model, hydraulic system model and controller model,the paper has carried on thejoint simulation, and collected relevant data at the scene of the experiment, the experiment curve and the curve of simulation data have been carried on the comparative analysis,toverify the accuracy and applicability of the joint simulation models.
