太原科技大学本科毕业设计（论文） 100/30T 通用桥式起重机结构设计 100∕30T General bridge crane machine design 学 院（系）： 机械电子工程系 专 业： 机械设计制造及其自动化 完 成 日 期： 2013 年6月10号 太原科技大学 Taiyuan University of Science and Technology 摘要 用估计的桥式起重机各结构尺寸数据对起重机的强度、疲劳强度、稳定性、刚度进行粗略的校核计算，待以上因素都达到材料的许用要求后，画出桥架结构图。然后计算出主梁和端梁的自重载荷，再用此载荷进行桥架强度和刚度的精确校核计算。若未通过，再重复上述步骤，直到通过。由于桥架的初校是在草稿中列出，在设计说明书中不予记录，仅记载桥架的精校过程。设计中参考了各种资料, 运用各种途径, 努力利用各种条件来完成此次设计. 本设计通过反复斟酌各种设计方案, 认真讨论, 不断反复校核, 力求设计合本设计采用许用应力法以及计算机辅助设计方法对桥式起重机桥架金属结构进行设计。设计过程先理;通过采取计算机辅助设计方法以及参考前人的先进经验, 力求有所创新;通过计算机辅助设计方法, 绘图和设计计算都充分发挥计算机的强大辅助功能, 力求设计高效。 关键词: 通用桥式起重机; 校核; 许用应力 100∕30T General bridge crane machine design Abstract First with the estimated size of crane structure data of the crane strength, fatigue strength, stability, rigidity for rough checking calculation, these factors have to be allowable material requirements, draw bridge diagram . Then calculate the main beam and side beams weight load, and then this load for bridge strength and stiffness of accurate checking calculation. If not passed, repeat the above steps, until the adoption. As the bridge of the primary sources listed in the draft, not in the design of manual record, record only the essence of the school bridge process. Design a variety of reference materials, using various means, to use a variety of conditions to complete the design of the appropriate design of a variety of designs through repeated, serious discussion, constantly re-checking, and strive to design and reasonable; through the adoption of computer-aided design and reference previous advanced experience, and strive to be innovative; by computer-aided design, drawing and design calculations are a powerful full computer accessibility, and strive to design efficient.Keywords:Bridge crane ; verification; allowable stress 目 录 第一章 总体设计方案.............................................................................................................1 1.1 基本参数 1 1.2 总体结构尺寸 1 1.3 材料的选择及许用应力
