JDCC1000型履带式起重机底盘的设计 摘要 履带起重机是工程起重机行业的一个重要门类，是现代工程建设施工中不可缺少的大型设备之一。本文简要介绍了履带起重机的结构和特点，并针对200吨级履带起重机的底盘进行了设计。 (1) 车架、履带架、四轮一带的方案设计。根据整机的稳定性、载荷状态、运输尺寸、承载等各种需求，进行了车架、履带架、四轮一带的结构方案设计，运用Proe三维绘图软件绘制完成三维模型，完成相关部件的装配，检查了相关部件的干涉关系。 (2) 车架、履带架、履带板的有限元计算。利用功能强大的ANSYS有限元分析软件对车架、履带架的结构方案进行优化分析，优化了车架、履带架的箱型截面和各主板及加强板的尺寸，得到了车架、履带架的理想结构。并对履带板进行有限元分析，优化提升了履带板的结构。车架、履带架包括履带板都充分采用变截面变板厚的设计理念，以减轻底盘质量，充分发挥材料性能。 (3) 牵引力计算及马达选型。通过计算整机最大的行走阻力，确定需要的牵引力。经过对几种行走减速机方案的比较，确定了行走减速机的设计方案，完成了行走马达的选型设计。并对上车匹配的发动机、行走泵的参数进行了验算。 (4) 针对履带底盘的工作特点，动作需求，设计了履带底盘的液压、电气控制系统。 关键词：履带起重机 履带底盘 有限元 行走机构 THE CHASSIS DESIGN OF JDCC1000 CRAWLER CRANE Abstract Crawler crane is an important category of the construction crane industry,is one of the indispensable equipment in modern engineering construction. This paper briefly introduces the structure and characteristics of crawler crane, and for the 200 tons crawler crane chassis design is introduced in detail. ( 1) Design for the frame, the crawler frame and the four round area. According to the overall stability, loading, transport, carrying various demand size, the frame, the crawler frame, four round area structure plan design, using Proe 3D drawing software rendering 3D models, complete the relevant parts of the assembly, check out the relevant parts of the interference between. ( 2) Finite element calculation for the frame, the crawler frame and the crawler plate. Using the powerful finite element analysis software ANSYS, the frame of crawler frame structure optimization analysis, optimization of the frame, the crawler frame box section and the motherboard and the strengthening plate size, obtained the ideal structure of frame, the crawler frame. And the track plate finite element analysis, upgrading the track plate structure. Frame, includes a track plate track frame are fully adopts the variable cross-section variable thickness design concepts, in order to reduce chassis quality, making full use of the material property. ( 3) calculation for th
