機車車輛沖擊
英文
impact of rolling stock-
Roll over protective structure ( rops ) is a device which installs on out of construction vehicle. the main functions are : when the vehicle rolling over. rops can prevent the vehicle from rolling over further, and reduce the possibility of rolling vehicle injures operator ; when the vehicle traveling on freezing soil. concrete and rock, it has large resist continuous impact ability ; when the vehicle overturning rops can support the whole vehicle. arrangement of falling object protective structure ( fops ) can block objects ( such as trees, rocks ) so that supply protection for operator. this problem is that research rolling over and falling objects protective structure of bulldozer by learning research condition of rops / fops and relative lay down international standard. on the base of theory analysis. detrudes counting formula of rops / fops deformation through founding mechanics analysis model of rops / fops at the stage of elasticity and plastoelastic. and finds a set of feasible nonlinear finite element analysis counting. lt calculates rops / fops plastoelastic deforma variable of 320hp bulldozer, bulldozer has been carried out by optimizing design method
其主要功能是:當車輛滾翻時, rops能刺入未凍土壤而阻止車輛的進一步滾翻,降低滾翻的車輛對系著安全帶司機軋傷的可能性;保證rops在碰撞和沖擊變形不大的地面(如凍土、混疑土上、巖石)時,能具有相當大的抗連續沖擊能力;當車輛已經處于顛覆狀態時,已經變形的rops應能支撐住整車。落物保護裝置(簡稱fops ) ,其構件的布置方式要能遮蔽墜落的物體(如,樹木、巖石等) ,以便對司機提供適當的保護。本課題主要通過了解國內外有關對rops fops的研究情況和有關國際標準的制定,對大型推土機傾翻和落物保護裝置進行研究,在理論分析的基礎上,通過建立rops fops的力學分析模型,推導彈性、彈塑性階段rops fops變形的計算公式,建立一套可行的rops fops的非線性有限元分析計算方法。Its unique entirely - solid state, simple configuration, wide dynamic range, short starting time, high antibounce ability, low - cost, small - cubage, light - weight, low - power waste make it not only compatible for the civil industry field but more for martial application. for the advantage as above, the optic gyro is very potential to the strap - down inertia navigation system
它代表了慣性儀表與元件發展的一個新方向,與傳統的機械陀螺相比其獨有光學陀螺儀的全固態、結構簡單、動態范圍寬、起動時間短、剛沖擊能力強、成本低、體積小、重量輕、功耗低,使其不僅適合於民用工業領域,而且更適合於車輛、各種軍事上的應用。Laser - cut steel armour providing full protection of all parts of the vehicle designed to contain the driver and the passengers against a high - level multi - impact ballistic assault and or hand - grenade ( blast and fragmentation ) attack with modern military weapons
車輛的防彈設計採用激光切割的防彈鋼板,可以使車輛獲得全面的保護,並對司機和乘客提供高級別的軍用槍支子彈射殺、軍用手雷爆炸的沖擊波和彈片及其他軍用武器的殺傷保護。Over the years, lrt technology has been upgraded to counter the negative effects of traffic jams, noise, environmental damage, air pollution, etc. featuring a small radius of curvature, multiple car units, modulated train set, enlarged cars both in transverse and longitudinal directions, low car floors, streamlined car design, advanced control systems, and flexible right of way, modern lrt systems have been successfully adopted to most environmental and social needs. they adequately display their merits as transportation systems ; i. e., the lrt system is able to co - exist with automobiles. the low car floor means that roads can act as station facilities, and passengers can get on and off the cars in the street
輕軌運輸系統lrt源起於歐洲街道電車street car ,街道電車一度在都市捷運化與私人機動化的浪潮沖擊下迅速沒落,但隨著都會地區機動車輛不斷增加,道路交通阻塞噪音環境破壞排放廢氣污染問題嚴重惡化之際,輕軌車輛技術已不斷提升,具備小轉彎半徑能力的聯結式車廂模組化列車編組車廂斷面長度加大加長低地板車廂流線型車廂設計,搭配先進控制系統及彈性的路權型式,使現代化輕軌系統具備有與生活空間結合重視環境問題與社會情勢並活用進化街車之都市交通工具等特徵與優點,如高性能輕軌列車與汽車共存,低底盤的車廂創造無障礙車站空間,道路即是車站設備,旅客可以在街區上下車,提供沿線居民高度的便利性,消除交通堵塞噪音及空氣污染等,輕軌系統並與街景充分的調和,成為活動的都市意象。Abstract : the tilter is a kind of heavy duty unloading installation, which needs frequent starting. a control system which consists of smc is disussed in this paper. this system has the features of simple structure, stable starting, accurate positioning and small impact to automobles and mechanical equipments
文摘:翻車機是需頻繁啟動的大型卸車設備,以smc組成的翻車機控制系統結構簡單、啟動平穩、定位準確,對車輛及機械設備的沖擊小。The dynamic interaction between vehicle and track is one of fundamental problems among railway wheel / rail contact transporting system, it directly constrains the increase of railway running speed and load - carrying. the paper presents the computer simulation on the wheel / rail impact response at a rail joint. the results of the the simulation are compared with that of the experiment, and the model is validated
