【摘要】 本文利用可靠性理论对拖拉机零件磨损量数据进行统计分析,以及如何评价拖拉机磨损件的可靠性。论述了磨损量分布计算方法,便于在任意工作时间测定磨损量。在此基础上。又按容许磨损量从理论上来确定拖拉机零件在规定工作时间时的可靠度,以及在给定可靠度条件下的耐磨寿命,后者可用来作为拖拉机零件中进行维修或更新的依据。更多还原

【Abstract】 By using the relibility theory,the data of the tractor parts’wearing capacity were statistically analysed,and how to evaluate their reliability, was studied The calculation method of the wearing capacitiest distribution was also discussed in order that the wearing capacity could be optionally surveyed during operation.On the basis of the results,the tractor parts’ reliability in stipulative work time was determined according to the allow- able wearing capacity theoretically and the wear-life was determined according to the stipulate reliability,the later can be used as the basis of repair and replacement of the tractor parts.更多还原
