摘要:
本文设计了一组双应力交叉步降的气缸加速寿命试验并进行试验。文中讨论了双应力交叉步降试验相比于常规寿命试验和双应力恒定试验的效率优势，使用了累计效率模型和GLL-Weibull模型对试验数据进行了分析。最终通过该方法获得的寿命数据有较高的精度，而且试验效率大大提高。该试验方法有着很大的发展空间。A Double-Crossed Step-Down-Stress Accelerated Life Testing (DCSDS-ALT) for pneumatic cylinder is designed and carried out in this paper. The paper also discusses the superiority on efficiency of DCSDS-ALT compared with conventional life testing and Twin-Stress Constant Life Testing. The Cumulative Effect Model and GLL-Weibull Model are used in the conversion and analysis of the statistic. The result of the test got satisfied precision, and DCSDS-ALT promotes efficiency signifi-cantly. This method has huge potential on development.
