【摘要】：近年來,隨著世界經(jīng)濟不斷的發(fā)展和全球貨物運輸量不斷的增加,具有高效、低耗、及時、靈活的多掛汽車列車已經(jīng)在西方發(fā)達國家開始承擔起重要的運輸角色。在全球經(jīng)濟發(fā)展大潮和我國公路網(wǎng)絡(luò)迅速構(gòu)建的環(huán)境下,多掛車列車成為我國主要的運輸工具已是必然趨勢。目前我國主要大噸位公路交通運輸還是以單掛汽車列車為主,其主要原因是人們對這個龐然大物道路通過性和駕駛操作靈活性缺乏了解。本論文以多掛汽車列車中的雙掛汽車列車為研究對象,首先以車輛通過性為研究目的對整車進行結(jié)構(gòu)簡化。采用圖解法結(jié)合多體動力學對整車的轉(zhuǎn)彎過程作出理論計算。然后在Adams中驗證理論計算,得出該雙掛汽車列車的轉(zhuǎn)彎半徑為17.3 m。通過該車轉(zhuǎn)彎過程分析對駕駛員的實際操作作出指導。再結(jié)合我國實際道路情況,對該車城市道路的換道、交叉路口轉(zhuǎn)彎等實際情況作出仿真分析,從而客觀的評價該車的轉(zhuǎn)彎機動性。最后發(fā)現(xiàn),該車轉(zhuǎn)彎過程中,掛車2對牽引車的跟蹤能力和自身回正能力較差。針對這一問題,本文就車輛設(shè)計的角度提出了改進方案。在掛車1和掛車2的鏈接裝置平板拖車處增加差速裝置,結(jié)果顯示該方案明顯提高了整車的幾何通過性。通過本文的研究,可以掌握雙掛汽車列車在我國城市道路的適應(yīng)能力,同時可以為雙掛汽車列車在我國城市道路上的運用提供理論支持和參考。更加快了雙掛汽車列車在我國前進的步伐。
[Abstract]:In recent years, with the continuous development of the world economy and the increase of the global cargo transport volume, the high efficiency, low consumption, timely and flexible multi-trailer train has begun to play an important role in the western developed countries. With the development of global economy and the rapid construction of China's highway network, it is an inevitable trend that multi-trailers become the main means of transportation in China. At present, the main highway transportation in our country is mainly single-trailer train, which is mainly due to the lack of understanding of the road passage and driving flexibility of this huge object. In this paper, the dual-trailer train in the multi-trailer train is taken as the research object. Firstly, the structure of the vehicle is simplified for the purpose of vehicle passing. Using graphic method and multi-body dynamics, the turning process of the whole vehicle is calculated theoretically. Then the theoretical calculation is verified in Adams, and the turning radius of the dual-trailer train is 17.3 m. The actual operation of the driver is guided by the analysis of the turning process of the vehicle. Combined with the actual road conditions of our country, this paper makes a simulation analysis on the actual situation of the vehicle's urban road change and turning at the intersection, so as to objectively evaluate the turning maneuverability of the vehicle. Finally, it is found that the trailers 2 have poor tracking ability and self-correction ability in the turning process. In order to solve this problem, this paper puts forward the improvement scheme on the angle of vehicle design. The differential device is added to the connecting device of trailers 1 and 2, and the results show that the scheme improves the geometric passage of the whole vehicle obviously. Through the research of this paper, we can master the adaptability of the dual-trailer train in the urban road of our country, and provide the theoretical support and reference for the application of the dual-trailer train in the urban road of our country. It is even faster that the dual-trailer train is advancing in our country.
