摘　　要：大功率液力变矩作为特种车辆底盘动力传动系统的关键部件,由于在产品研制初期子样数少,台架可靠性考核不充分,生产装配工艺不稳定等导致产品的测试、维修和保障性只能依据经验设计缺乏科学的规划;研究通过对变矩器可靠性数据的分析,建立了大功率液力变矩混合威布尔可靠性分析模型,并对不同里程下液力变矩器的可靠性和出现的薄弱环节,检查方法等进行预计;对生产环节可能出现的早期故障,制订了强化出厂试验方案;针对大功率变矩器在使用过程中的故障和维修数据分析,对装备的测试、维修和保障性重新进行了科学的规划与设计。High-power hydraulic torque is taken as a key component in special vehicle chassis power transmission system,due to in the early stage of product development,there are the problems of small number of subsamples,insufficient assessment of bench reliability and unstable assembly process,as a result,product testing,maintenance and support can only rely on the experience design and lack of scientific planning.Through the analysis of torque converter reliability data,a high-power hydraulic torque hybrid Weibull reliability analysis model is established,and the reliability of hydraulic torque converter under different mileages,the weak links and inspection methods are estimated.For the early failures that may occur in the production process,an intensive test plan is formulated before the product leave factory.By the fault and maintenance data analysis for the high-power torque converter,the testing,maintenance and guarantee of equipment are scientifically planned and designed again.
