摘要
我国铁路货运实现了跨越式的发展以来,铁路货运能力得到了明显的提高,但依旧无法满足逐渐增长的货物运输需求。近年来,为了满足大秦线开行重载运煤列车的需要,我车,并阐述了研制60吨级专用平车研究的必要性和意义。
论文介绍了从建国初期到本世纪初过程中,每个发展阶段具有代表性的一些基本车型,每种车型的基本结构以及所存在的问题。随着新材料,新工艺,新技术的不断诞生以及铁路货车转向架,车钩,制动装置等配套
零部件的技术完善,如今,研究开发60t专用平车已经成为现实。
论文中列举了三种可供选择的总体设计方案,通过方案之间的优缺点对比选定一种相对较为合适的方案进行设计。首先进行主要参数和结构的选取,对现有的车型进行研究、改进,选用新型材料、结构已实现降低自重,增大载重的设计要求。确定了设计基本参数后再对车体底架等进行细化设计,并对每个部件进行选型和选材。
最后,论文详细介绍了车辆的制动系统,确定了制动方式及制动系统选型,并且对紧急制动时的制动距离进行了校核。通过计算校核了车辆的最小曲线通过半径以及曲线通过时车端部和中部能够通过限界,确保了车辆设计的安全性,可靠性,合理性。

Abstract
Since China’s rail freight develops by leaps and bounds,the rail freight capacity has been significantly improved. However, it is still unable to meet the growing demand for cargo transport. In recent years, in order to meet the need of Datong-
Qinhuangdao line of coal trains, China has developed a number of dedicated 60tcoal flat car. This paper also states the necessity and significance of the dedicated 60t coal flat car.
This paper introduces representative basic model of each development
stage from the found of China to the beginning of this century, discussing the basic structure of each model and the related problems. Nowadays, with the development of new materials, techniques and technologies as well as the improvement of the railway freight car bogie, coupler, brake parts and other supporting technical, the dedicated 60t coal flat car has e reality.
This essay lists three options for the overall design. paring the advantages and disadvantages among three options, a relatively more appropriate program design was selected. In the first place, main parameters and structures will be selected. Then, study and improvement of existing models will be done to select new materials and struct
