Evaluation of Operating Performances Based on Median Damage Load Spectrum

Abstract

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.
