Mechatronics And Hydraulics Integration Simulation Of Lifting Actuator For Aerial Working Platform

Aerial Working Platform(AWP) is a kind of engineering equipment,which is used to convey the workers and equipments to the aerial appoint place for working.Recently because that the field of it application is expanded day by day,the height of operation becomes more high.In this situation,it is necessary and important to research the mechanical properties of the working arm and the Reliability Analysis(RA) of lifting actuator hydraulic system in the design field of aerial working platform for ensuring the personal safety in aerial working.In this paper,the research object was the working arm of the folding AWP with 14 meters.Based on the detailed analysis of working arm structure,the finite element model of the working arm was established reasonably with the ANSYS.Then based on the static structural analysis of working arm in three typical conditions,we get the dangerous working condition,the stress distribution,the deformation distribution.By checking the strength and stiffness,the design of working arm met the demands.To the vibration and shock because of frequently starting and braking in the operation of folding AWP,the Reliability Analysis (RA) methods of lifting actuator hydraulic system for AWP based on the MATLAB/SIMULINK were developed and determined,which verified the reasonableness of the parameters taken.Then based on AMESIM,the Physical model of the hydraulic system was built and simulated.The results showed that the simulation analysis consisted with the reliability analysis.According to the research in the paper,the method,that analyzing the static structural and follow-up optimizing structures by using ANSYS,can meet the safety requirements,shorten design period,reduce the cost of design and gain accurate result.The research provides the important reference values for solving similar engineering problems.And then,the RA based on the MATLAB/SIMULINK and the Simulation of Control System based on AMESIM,have higher practical value in Performance analysis of the hydraulic system and applied research in intelligent control.
