基于T-S故障树的葡萄修剪机液压系统可靠性分析
Reliability Analysis of Hydraulic System for Grape Pruning Machine Based on T-S Fault Tree
摘要
Abstract
Pruning operation is a key link in improving grape yield and quality,and the hydraulic system,as the core of the grape pruning machine,plays an important role in the reliability of the machine's operation.A fault tree for the hydraulic system of a grape pruning machine was established using T-S fault tree analysis method,with hydraulic system failure as the top event.The calculation results indicated that the system had a minor failure rate of 1.32 × 10-5 h-1 and a severe failure rate of 8.55 × 10-5h-1.Analyzed the probability importance and critical importance of the hydraulic system of the grape pruning machine.When the hydraulic system was on a semi-faulty state,the speed control valve and directional valve had a greater impact on the probability importance,while the relief valve and hydraulic pump had a higher critical importance.In severe fault conditions,the motor and hydraulic cylinder had a significant impact on probability importance,while the critical importance of directional valves,hydraulic pumps,and motors were relatively high.Related research can serve as a basis for troubleshooting grape trimmers,which was beneficial for improving maintenance efficiency and providing theoretical support for system improvement.关键词
