Numerical analysis of dropper stress under a moving load based on the uplift displacement for a high-speed railway

Caizhi Yang,
Xinxin Shen,
Like Pan
et al.

Abstract: <abstract> <p>The most essential cause of the fracture of the dropper is the effect of alternating stress for a long time. Therefore, in order to ensure the safe operation of high-speed railways, the influence of moving loads on the stress of a dropper was investigated in this study. Due to a high-voltage catenary system, it is very difficult to measure the moving load. Thus, the uplift displacement measured by some software and hardware devices has been applied to the contact wire instead of the … Show more
