Hydraulic System Design Of Two-layer Parking Equipment And Its Dynamic Characteristics Analysis

With the development of living standard more and more people own cars,to find a parking place become a big problem.Now there is not enough space to parking.One of the key ways to solve this problem is use parking equipment which has high space utilization.This paper studies about two layers parking equipment.Paper target hydraulic system design of two-layer parking equipment and analysis features for key return circuit.According to the functional requirements of every motion,to calculate walking hydraulic circuit?rotary hydraulic circuit?lifting hydraulic circuit.As well as using the measure of pressure compensation method in order to guarantee steady speed in running.Rotary circuit,and the lifting circuit though using hydraulic lock to implement anywhere locking.To verify this equipment this paper builds mathematical model of main hydraulic parts to study dynamic characteristics of hydraulic system,and using AMESim to build models for simulation,and analysis characteristics of speed?pressure and so on.To simulate and analyze the speed control characteristics of lifting circuit by MATLAB/Simulink.This study for design other products provide a basis theory for later research and it is significance for reducing the cost,shorting time.
