, 1982 传统的寿命估算方法是名义应力法,这种方法根据构件的名义应力历程、构件的S-N曲线和累积损伤理论估算寿命。这种方法需要做构件的S-N曲线,而且估算的结果常常很不精确。近年来国外发展起一种新的寿命估算方法,这种方法根据构件关键部位的弹塑性分析,将名义应力历程转化为关键部位的局部应力-应变历程,根据局部应力-应变历程和材料的疲劳特性及累积损伤理论进行裂纹形成寿命的估算,称之为局部应力-应变法 ...

Gaoya dianqi, 1992 现代的SF6断路器制造技术,不仅能把断路器的开断能力做得很高、而且电寿命也很长,在额定电流下可达到几千次,额定短路电流下也能做到几十次,因此不检修周期可达10～20年。要保证这么高的电寿命必须有更高的机械寿命才有可能。因此,研究提高断路器的机械寿命,是生产厂家的重要课题之一。 我厂和西安高压电器研究所等兄弟单位联合研制的LW8—35/1600 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Sodium‐ion capacitors (SICs) offer high energy and power density with long cycle life, but developing kinetically compatible electrodes remains challenging. This work developed a simple and sustainable strategy to synthesize homologous carbon electrodes from the inner shells of durian husks (ISDH) for high‐performance SICs.

, 2007 本实用新型公开了一种长寿命旋转放电电极，包括圆盘电极及与该圆盘电极连接的驱动装置，所述圆盘电极圆弧边缘断面为尖角形状。由于上述旋转电极包括圆盘电极、旋转轴、传动装置及电动机，圆盘电极在电动机的带动下可匀速旋转，圆盘电极边缘断面为尖角状，从而保证圆盘电极放电指向性好，在高重频脉冲激光诱导放电过程中，由于圆盘电极的不停转动，每次放电作用在圆盘电极边缘的不同点上，大大减小了持续放电造成的电极尖端的过热烧蚀现象，并且电极放电由一个点扩展到整个圆周线上，减少了单个电极上的热量累计，同时，圆盘电极热容量大 ...
