以直升机传动系统组件为研究对象,采用正交设计,设计了一套新的磨损影响因素可靠性试验,通过极差分析法和方差分析法对试验数据进行处理分析,比较两者优劣,确定对直升机机械组件磨损的主、次要影响因素,以此证明该可靠性试验技术的实用性与合理性。 Taking the components of the helicopter transmission system as the research object, a set of new reliability test of wear factors was designed by using orthogonal design. The test data were processed and analyzed by the range analysis method and the analysis of variance method. The advantages and disadvantages of the two methods were compared The primary and secondary influencing factors on the wear of helicopter mechanical components are used to prove the practicability and rationality of the reliability test technology.
