高空作业车举升执行机构液压系统可靠性分析

Reliability Analysis of Lifting Actuator Hydraulic System for Aerial Work Platform

针对折叠式高空作业车运行过程中由于频繁启动和制动引起的明显振动和冲击现象,提出了基于MATLAB/SIMULINK平台的高空作业车举升执行机构液压系统设计可靠性分析方法;建立了系统可靠性分析数学模型。通过MATLAB/SIMULINK分析,得出该控制模型的仿真结果,对折叠式高空作业车举升执行机构液压系统的性能分析和智能控制的应用研究具有实际应用价值。

Due to vibration and shock caused by frequent start and brake in the operation of folding Aerial Work Platforms（AWP）,the Reliability Analysis（RA） methods of lifting actuator hydraulic system for AWP based on the MATLAB/SIMULINK were developed.The mathematical model with system reliability was established.The simulation results by MATLAB/SIMULINK could be applied to analyzing the performance of hydraulic system and researching intelligence control.
