摘　　要：为量化评估转动对数周期天线等机电类设备的整体可靠性,本文研究了电气元器件的可靠性预计和结构构件的可靠度计算,基于应力、强度干涉理论提出了一种通过总失效率来评估机电设备整体可靠性的方法。通过研究电子器件和结构构件的可靠性和失效概率,通过汇总计算的机电设备总失效率,得出整机的MTBF(平均故障间隔时间),从而量化评估机电设备的整体可靠性。最后,本文以某转动对数周期天线产品为例,分析了设备总失效率和整机MTBF的计算过程,通过本方法可在方案、设计阶段量化评估机电产品的整体可靠性,以指导可靠性设计,提高产品的最终使用可靠性。For quantitatively evaluate the overall reliability of mechatronics equipment such as rotating log-periodic antennas,this paper studies the reliability prediction of electrical components and the reliability calculation of structural components,and presents a quantitative reliability assessment method by total failure probability based on stress and strength interference theory.By studying the reliability and failure probability of electronic components and structural components,the total failure probability of the mechatronics equipment can be calculated,so the MTBF(Mean Time Between Failure)of the equipment can be calculated,and the overall reliability of equipment can be quantitative estimated.Finally,this paper takes a rotating logarithmic periodic antenna product as an example to present the process of total failure probability and MTBF calculation.Through this method,the overall reliability of the mechatronics equipment can be quantitatively evaluated in the scheme and design stages to guide reliability design and improve the final reliability of the product.
