摘要

负荷谱是可靠性分析的基础。在典型的试验场中，为某一模型选择合适的算子，有利于负荷谱的获取。不同的操作人员造成的不同的运行性能具有多重评价指标的特点。提出了一种基于中值损伤的综合评价方法。将该方法应用于挖掘机试验现场的实际运行性能评价。对比结果表明，所提出的方法是可行的，并且当涉及更多指标时，将更加方便。该方法为编制负载谱采集规范提供了理论参考，并为运行性能评价提供了一种新的方法。

Evaluation of Operating Performances Based on Median Damage Load Spectrum

Load spectrum is the basement of reliability analysis. Selecting a suitable operator for a certain model in a typical experiment field is of benefit to the acquisition of load spectrum. Different operating performances caused by different operators have the characteristics of multiple evaluation indicators. In this paper, a comprehensive evaluation method based on median damage is proposed. The method is applied to evaluate the actual operating performances in the experiment field of the excavator. Comparative results show that the proposed method is feasible, and will be more convenient when more indicators are involved. The proposed method provides a theoretical reference for the compiling of load spectrum acquisition specification, and proposes an additional method for the evaluation of the operating performances.
