In accordance with the features of hydraulic pump, this paper analyzes the failure mode and selects the sensitive stress. According to failure effects that sensitive stresses impose to hydraulic pump and researches that the U.S.A life test standardization develop, we can drive at the conclusion that the synthetic stresses reliability test can verify the reliability and the life of hydraulic pump. Because hydraulic pump has many characteristics such as high price, long life and small test samples,...

In accordance with the features of hydraulic pump, this paper analyzes the failure mode and selects the sensitive stress. According to failure effects that sensitive stresses impose to hydraulic pump and researches that the U.S.A life test standardization develop, we can drive at the conclusion that the synthetic stresses reliability test can verify the reliability and the life of hydraulic pump. Because hydraulic pump has many characteristics such as high price, long life and small test samples, this paper also analyzes the statistical method for synthetic stresses life test under variable load spectrum. The life test experiments indicate that the method of synthetic stresses life test are satisfied to analyze the life of mechanical-electrical products.

针对液压泵这种典型机电产品的特点,在分析了液压泵故障机理的基础上, 确定了能诱发产品关键故障模式的敏感应力.通过分析敏感应力对液压泵故障的影响及美军标寿命试验载荷谱的发展,得出了利用综合敏感应力可以进行液压泵综合应力寿命验证的结论.还针对液压泵价格贵、寿命长、试验样本少的特点,分析了液压泵综合应力寿命试验统计方法,通过试验证明了它的有效性

The failure mode and failure mechanism of hydraulic pump are analyzed in this paper, and then the temperature,pressure,rotating speed are decided primary factors for synthesis stress and the conclusion that the synthesis stress can be used in validating the life of the pumps is received.In the other hand,the statistical method of the synthetic stress life test for the hydraulic pumps is also analyzed and its validity is validated by test in this paper.
