一、前言在降落伞的试验和使用事例中,仅仅因为一根连接绳断裂致使开伞程序错乱,甚至主伞被封在伞包中,从而酿成大事故的教训往往是十分渗重的。事故原因的分析故然可以采用其它各种手段,但是借助扫描电子显微镜,依据锦丝绳的断口显微特征,确立锦丝绳的致断原因,却是一项具有吸引力的尝试。本文即以降落伞锦丝绳在使用中的几种常见断口显微特征,说明这一故璋分析的可行性。
I. Introduction In the experiments and examples of the use of parachutes, the lessons learned from causing major accidents are often very much at odds with the parachute procedure being confused and the main parachute being enclosed in an umbrella bag simply because of a broken connecting rope. Analysis of the cause of the accident, of course, can use a variety of other means, but with the help of scanning electron microscopy, according to the microscopic characteristics of the wire rope fracture, to establish the cause of wire rope breakage, but it is an attractive attempt. In this paper, the parachute Kam wire rope in use of several common fracture microscopic features, indicating the feasibility of this analysis so Zhang.
