本文根据试验场58台国产叉车可靠性试验和上海、南京港国产及进口的17台叉车使用中的240余故障实例,进行了故障模式分析。从可靠性基本理论出发,对叉车故障的概念及故障等级作了分析。从故障发生的时间、频次、危害程度出发,研究了故障对叉车可靠性的影响,提出了叉车可靠性评价的单项指标及综合指标。
In this paper, based on the reliability test of 58 domestic forklifts in the test ground and more than 240 failure examples in the use of 17 forklifts made and imported in Shanghai and Nanjing Port, the failure modes are analyzed. Based on the basic theory of reliability, the concept of forklift failure and the level of failure are analyzed. Based on the time, frequency and damage degree of the fault, this paper studies the influence of the fault on the reliability of the forklift, and puts forward the single index and comprehensive index of the reliability evaluation of the forklift.
