为了提高我国铁路的货运能力，并且能较好地适应既有铁路线桥的实际状态，开发载重70t、轴重25t的新型通用货车已成为一个重要举措。今在70t级新型通用货车的代表车型C70型通用敞车的基础上研制设计高边敞车，命名为C70GB。C70GB型高边敞车系通用敞车，该车供在中国准轨铁路装运高大货物、或比重小的散粒货物使用，亦可用于自营铁路的固定编组运输。在给定车辆主要性能及尺寸参数的条件下，完成车辆总体及大部件等设计，包括底架、侧墙、端墙、车门等结构，以及钩缓装置、转向架的选用。结合设计要求，阐述70t级货车的关键技术和总体设计思路，包括车体轻量化设计、25t轴重转向架技术等。设计前期的工作主要有调研过程、分析课题、进行方案的选取和设计，最后通过计算机绘图软件完成设计车辆总体和大部件，本文在绘图的基础上结合理论分析和计算加以详细说明和介绍。通过采用新材料、新技术和新结构设计而成的C70GB型高边敞车提高了车辆的技术性能，提高了铁路的货运能力，奠定了我国铁路货车载重由60t升级到70t级的基础地位。In order to improve China's railway freight capacity， and can better adapt to the existing railway line bridge of the actual state of development of load 70t， 25t axle load of new GM vehicles has become an important Today in the 70t class representative of the new GM truck models C70 Universal Gondola developed based on the design of high-side gondola， named C70GB C70GB common type high-side gondola gondola system， the vehicle for standard gauge railway in China， the tall ship the goods， or goods， the proportion of small shot used， can be used for self-rail fixed grouping In a given vehicle performance and size parameters of the main conditions to complete the vehicle population and large parts such as design， including the chassis， side walls， end walls， doors and other structures， as well hook slow device， bogies With the design requirements， explain the key 70t class truck technology and overall design ideas， including lightweight body design， 25t axle load bogie Preliminary design work are the research process， analysis of issues， the program selection and design， computer graphics software to complete the final adoption of the overall design of vehicles and large parts， this article on the basis of the drawing and calculation to be combined with theoretical analysis and detailed Through the use of new materials， new technologies and new design made of high-side gondola C70GB type of technology to improve vehicle performance， improved rail freight capacity， China has laid a railway wagon load from the 60t to 70t class infrastructure to upgrade the 关键词：敞车；技术参数；结构；转向架Keywords: gondola; technical parameters; structure; bogie
As China's economy， economic and industrial restructuring and between all modes of transport more Traditional railway operation was not able to meet the needs of the market， rail freight to competition， it is necessary to rapidly adjust to construct a bargain， facilitate the timely， cost-effective and user satisfaction of modern logistics Thesis it is from the practical problems of railway freight transportation， rail freight has analysed the situation and analysis of rail freight to modern logistics transformation of the necessity and feasibility of railway freight transportation， determine the development of modern logistics ideas and goals that make the development of modern logistics and railway

Containerization is railroad freight development direction ， its significance synthesizing logistics cost to lessening entire society ， improving the efficiency and efficacy composing in reply international supply chain at home and abroad is Our country joins the WTO queen ， the railroad now that be welcoming the opportunity having come to development ， be confronted with austere Railroad the more fierce competition between transporting enterprise not only being that other transports the competition between way ， it returns back with frontage and other country with in the homeland facing the But our country railroad containerization system and how dyadic container through transport development are in starting phase at present，with the developed country is returning the certain gap back to Change the aspect that our country railroad containerization development lags behind only when on finding out our country railroad containerization have problem basis，ability makes our country railroad containerization exist with the progress developing ， promoting our country economy ， the social life， and make prosper in international environment of And the basis will be in the railroad containerization current situation synthesizing contrast home and abroad is listed in the main body of a book ， is discuss Chinese railroad containerization have problem ， is analyse the cause that our country railroad containerization lags behind， direction has carried out a thinking on development of future our country railroad containerization ， development of containerization has brought forward suggestion to accelerating a Problem is complementary:
With the deepening of China's economic reform， the adjustment of economic structure and the mode of transport between the increasingly fierce The traditional mode of operation of the railway can not meet market needs， and railways in order to remain invincible in the competition， must quickly adjust business strategy and build a smooth flow of goods， to facilitate the timely， economical， customer satisfaction modern logistics environment Paper is the practical problems from the rail freight， analyzes the situation faced by rail freight， rail freight analysis to the modern logistics and the necessity and feasibility of rail freight to determine the development of modern logistics ideas and objectives， proposed the development of modern rail freight logistics measures
