【摘要】：卡軌車是國內(nèi)外使用較為廣泛的礦井輔助運(yùn)輸設(shè)備。國內(nèi)現(xiàn)有的卡軌車大都采用鋼絲繩牽引,由于鋼絲繩在使用過程中的銹蝕、斷絲和磨損而使其強(qiáng)度下降,從而導(dǎo)致鋼絲繩斷繩事故的發(fā)生。在煤礦生產(chǎn)中,我國的礦井輔助運(yùn)輸事故,約占井下事故總數(shù)的30%,傷人事故約占13.5%,其中大部分事故都由運(yùn)輸設(shè)備制動系統(tǒng)的不完善(不能即時(shí)制動,制動系統(tǒng)失效等問題)引起的,這嚴(yán)重影響著煤礦的安全生產(chǎn)。本課題針對煤礦卡軌車制動方面存在的問題,主要做了以下幾個(gè)方面的分析與研究:通過對國內(nèi)外礦用軌道運(yùn)輸車輛制動系統(tǒng)研究現(xiàn)狀的分析,確立了新型卡軌車制動系統(tǒng)的設(shè)計(jì)方案;結(jié)合工程實(shí)際,確立了新型卡軌車的基本參數(shù)和基本結(jié)構(gòu);進(jìn)行了卡軌車力學(xué)模型的構(gòu)建和相關(guān)計(jì)算;對新型卡軌車系統(tǒng)機(jī)械結(jié)構(gòu)進(jìn)行了創(chuàng)新設(shè)計(jì),建立了卡軌車新型制動系統(tǒng)的Solid Works三維實(shí)體模型;基于ADAMS分析軟件,對卡軌車制動系統(tǒng)中的制動小車,進(jìn)行了虛擬試驗(yàn)仿真和整體性能的研究;利用有限元分析方法,對卡軌車制動系統(tǒng)中的重要零部件進(jìn)行強(qiáng)度分析。通過以上幾方面的研究,結(jié)果表明:本論文中對新型卡軌車制動系統(tǒng)的創(chuàng)新設(shè)計(jì)達(dá)到了預(yù)期的設(shè)計(jì)要求,其中關(guān)鍵零部件都滿足強(qiáng)度要求,使得新型卡軌車能夠?qū)崿F(xiàn)快速、及時(shí)、平穩(wěn)地制動。本文對新型卡軌車制動系統(tǒng)的設(shè)計(jì)研究,不論是在Solid Works軟件中對零部件的三維實(shí)體設(shè)計(jì),還是對卡軌車整車的虛擬裝配,再到對制動小車的動力學(xué)仿真和卡軌車整體性能的實(shí)驗(yàn)分析研究,以及通過運(yùn)用有限元分析方法,對重要零部件的強(qiáng)度分析,全部在計(jì)算機(jī)上完成,區(qū)別于傳統(tǒng)的設(shè)計(jì)方法:便于修改和結(jié)果的保存與交流,設(shè)計(jì)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.
