摘要: 对工程机械的废旧零部件进行剩余寿命评估是对其再制造的前提与基础。由于工程机械的作业环境较为复杂，传统的寿命预测方法存在过于繁琐与复杂的问题。本文以混凝土泵车臂架系统为例，以系统零部件失效数据和历史服役工况数据为基础，联合威布尔分布和ECC系统信息来评估臂架系统的剩余寿命。通过与传统的力学分析寿命评估的结果对比，提高结果准确度。并分析了臂架实际使用寿命与剩余寿命的可靠性，结合实际的零部件可靠性阈值，为再制造工程提供定量分析依据，也为再制造的剩余寿命评估提供了一种更为简单的方法。
Abstract: Residual life assessment of used parts of construction machinery is the premise and basis for its remanufacturing. Due to the complicated working environment of construction machinery, the traditional life prediction method is too cumbersome and complicated. In this paper, the concrete pump truck boom system is taken as an example. Based on the system component failure data and historical service condition data, the Weibull distribution and ECC system information are com-bined to evaluate the remaining life of the boom system. Improve the accuracy of the results by comparing them with the results of traditional mechanical analysis life assessments. The reliability of the actual service life and remaining life of the boom is analyzed, and the actual component reliability threshold is combined to provide a quantitative analysis basis for the remanufacturing project. It also provides a simpler method for the remanufactured residual life assessment.
