【摘要】：卡轨车是国内外使用较为广泛的矿井辅助运输设备。国内现有的卡轨车大都采用钢丝绳牵引,由于钢丝绳在使用过程中的锈蚀、断丝和磨损而使其强度下降,从而导致钢丝绳断绳事故的发生。在煤矿生产中,我国的矿井辅助运输事故,约占井下事故总数的30%,伤人事故约占13.5%,其中大部分事故都由运输设备制动系统的不完善(不能即时制动,制动系统失效等问题)引起的,这严重影响着煤矿的安全生产。本课题针对煤矿卡轨车制动方面存在的问题,主要做了以下几个方面的分析与研究:通过对国内外矿用轨道运输车辆制动系统研究现状的分析,确立了新型卡轨车制动系统的设计方案;结合工程实际,确立了新型卡轨车的基本参数和基本结构;进行了卡轨车力学模型的构建和相关计算;对新型卡轨车系统机械结构进行了创新设计,建立了卡轨车新型制动系统的Solid Works三维实体模型;基于ADAMS分析软件,对卡轨车制动系统中的制动小车,进行了虚拟试验仿真和整体性能的研究;利用有限元分析方法,对卡轨车制动系统中的重要零部件进行强度分析。通过以上几方面的研究,结果表明:本论文中对新型卡轨车制动系统的创新设计达到了预期的设计要求,其中关键零部件都满足强度要求,使得新型卡轨车能够实现快速、及时、平稳地制动。本文对新型卡轨车制动系统的设计研究,不论是在Solid Works软件中对零部件的三维实体设计,还是对卡轨车整车的虚拟装配,再到对制动小车的动力学仿真和卡轨车整体性能的实验分析研究,以及通过运用有限元分析方法,对重要零部件的强度分析,全部在计算机上完成,区别于传统的设计方法:便于修改和结果的保存与交流,设计效率高、成本小。
[Abstract]:Rail truck is a kind of auxiliary transportation equipment used widely in mines at home and abroad. Wire rope traction is mostly used in the existing rail cars in our country. The strength of wire rope is decreased due to the corrosion, breaking and wear of wire rope during the process of use, which leads to the accident of wire rope breaking. In coal mine production, mine auxiliary transportation accidents in our country account for about 30% of the total number of underground accidents, and wounding accidents account for about 13.5.The majority of these accidents are caused by the imperfection of braking system of transportation equipment. Brake system failure and other problems, which seriously affect the safety of coal production. Aiming at the problems existing in the braking of coal mine rail cars, this paper mainly analyzes and studies the following aspects: through the analysis of the present situation of the research on the braking system of the mining rail transport vehicles at home and abroad, The design scheme of the braking system of a new type of rail car is established. Combined with the engineering practice, the basic parameters and basic structure of the new type rail truck are established, and the mechanical model of the rail truck is constructed and the relevant calculation is carried out. The mechanical structure of the new type rail truck system is innovated and the Solid Works 3D solid model of the new type braking system is established. Based on the software of ADAMS, the virtual test simulation and the whole performance of the brake trolley in the braking system of the rail truck are carried out, and the strength analysis of the important parts in the braking system of the rail truck is carried out by using the finite element analysis method. Through the above research, the results show that the innovative design of the new type rail car braking system in this paper has reached the expected design requirements, in which the key components meet the intensity requirements, so that the new rail car can achieve fast. Brake in time and smoothly. In this paper, the design of a new type of rail car braking system is studied, whether it is the 3D solid design of parts and components in Solid Works software, or the virtual assembly of the whole rail truck. And then to the dynamic simulation of the brake trolley and the experimental analysis and research on the overall performance of the rail car, and the strength analysis of the important parts by using the finite element analysis method, all of which are completed on the computer. Different from the traditional design method, it is easy to modify and save and exchange the results, the design efficiency is high and the cost is low.
