万吨水压机活动横梁三维光弹性试验研究

An Experimental Study of 3-D Photoelasticity on the Moving Transbeam of Ten-thousand-ton Water-pressure Machine

本文采用三维光弹性试验方法对新设计制造的万吨水压机活动横梁的工作应力进行了分析与研究。试验结果表明最大应力发生在纵向筋板上和液压活塞柱的缸套处。这一结论与用有限元计算出的结果相一致,且两者的应力值误差在10％范围内。因此,我们认为本试验结果是可信的,为活动横梁设计的可靠性提供了试验依据。

The stress fields of moving transbeam of neuly designed and made ten -thousand -ton water - pressure machine were analysesed and investigated with the three - dimensional photoelasticity method in this paper. The results showed maximum stress often occured on the longitudinal stiffened plate and the hydraulicly loaded sleeve burrel, which was in accordance with that of finite element method. The errors between them were within 10 percent. Therefore, we thought the enperimental results were trustworthy and provided the testing basis for the probability of designing moving transbeam.
