市城小型公交客车总体布置设计--大学毕设论文

摘 要进展城市小型公共交通是法律规范城市短途运输市场、解决城市居民日常短途出行的重要措施。为满足城市短途客运的需求，必须开发结构先进、布置合理、性能优异且具有一定性价比的小型公交客车。本次设计首先分析了城市小型公交客车的进展现状与需求，在了解车辆的结构形式及主要参数对车辆性能的影响基础上，合理确定该车的结构形式及主要参数。然后综合考虑动力性、经济性、操纵性等要求，确定该车主要系统和总成的型式及参数。同时，为了设计出更加舒适的城市公交客车，采纳了空气悬架系统，并设计了空调系统。在保证这些特性的前提下，初步完成了对城市小型公交客车总体布置设计，并对该车的主要性能进行了分析计算。关键词：城市小型公交客车，总布置设计，动力性，经济性ABSSTRACTDeveloping urban miniature public traffic is an important measure to normalize short-distance transportation market and solve problems of daily short trip of urbanites. In order to meet the need of short transportation, miniature public buses with advanced structure, reasonable layout, excellent performance and effective performance price ratio must be developed. First of all, the design analyzed the developing status and needs of miniature buses, reasonably identifying the structure and main parameters of this bus based on knowing about effects of structure and main parameters on vehicle’s performance. Then, dynamic property, economical efficiency, and operability will be taken into consideration, making sure the main system and model and parameters of the bus. Meanwhile, in order to design more comfortable urban buses, air suspension system is employed, and air-conditioning has been designed. On the premise of those qualities, this design has preliminarily completed the overall layout design, and analyzed and calculated the main performance.KEY WORDS:urban miniature bus, layout design, dynamic property, economical efficiency目 录摘 要..........................................
