摘要
目的进行振动与冲击非常恶劣的履带车配套的某战场侦察雷达电子机箱结构件寿命预测和可靠性分析。方法通过故障模式分析和概率设计与分析,借助专业的概率分析软件,对机箱结构件进行失效概率分析和定量的寿命预测。结果量化出机箱结构件的工作风险时间,识别出重要件的设计参数,确定结构件的重要特性及检验要求,并形成重要特性检验单元明细表。结论参照上述分析结果,在进行机箱结构设计与加工的时候,对灵敏度较高的参数进行重点质量监控。
Objective To carry out lifespan prediction and reliability analysis on structural components of products matching thetrack vehicle under harsh vibration and impact circumstances. Methods Through the design and analysis of failure mode analysisand probability, and with the aid of the probability of professional analysis software, the failure probability analysis and the quantitativelife prediction of chassis structure were carried out. Results The work risk duration of chassis structure was determined. Importantparts of design parameters were identified. Important characteristics and inspection requirements of the structure were determined.And schedule of inspection unit form important characteristics was formed. Conclusion With reference to the aboveanalysis, in structure design and processing, monitoring the quality of higher sensitivity of parameters is the key.
