Accident Investigation And The Reasons. Derailment Analysis

The safety of railway transportation refers to many homes, It influences society widely and is the stress of safe production work for our paftv and our country all along Because the prihciple of no-loaded train derailment is very complicated and the reasons of derailment . have many aspects , the progress of study of derailment problem is little. It is important to inrestigate, analyse and study the spot accident quickly, timiely, odjectively and comprehensirely and find out the true reason of the accident, so that effective and precalltious measures can be laid down with a definite purpose.Based on the summarizing derailment theory , the ordinary program of accident inrestigation and handle and the accident inquiry of no-loaded train derailment, this paper has analysed and set forth the diversity of no-loaded train derailment problem and the complex of inquiry and handle combined with serai specific examples inwork, analysed stressly the reason of the train derailment accident on You-shui Bridge of Tiao-Liu Railway Line. The following conclusions can be come to:1) The promint problems of railway safety have -six respects:road junction safety, construction safety, no-loaded train derailment , freight train loading , abnormal driving , society order , Except for no-loaded train derailment , the remains may be solved by tightening up the management. The principle of no-loaded train derailment is wery complicated and the reasons of derailment have many aspects.2) The inquiry of accident is the strart of analyzing and handling the Accident. The original materials got by spot in westigation are the important bases for all the later work. Sothe spot investigation work must be quick, timely, objective and comprehensive. Itmust awoid the influence by man-made factors, find out the true reason of accident so that effectine and precautions measures can be laid down with a definite purpose.3) Which the sliding performance of Turning 8A steering -rack is relatively Bad is one of the important factors of no-loaded train derailment. we must Quicken the transform of Turning 8Asteering-rack and the development of Freight train new steering-rack. We can solve the problem of backward technique about freight train steering-rack in essence in our country so as to Improve the dynamic performance of rolling stock, enhance the sliding speed of freight train and ensure safety in the freight train running.4) Which the bridge crossmg amplitude of vibration is relatively large is the important factor of brmging out ne-loaded tram derailment .stress must be laid on testmg of the bridge , selp-vibration frequence and crossmg amplitude of vibration about the bridge must be known. Measures must be taken to bridges which crossmg amplitudes of vibration are over-limited.
