电动双梁起重机桥架结构设计
摘要
本设计是在保证金属结构安全可靠、经济合理的前提下，选择起重机金属结构材料时，通过金属结构的形式、连接形式、承受的载荷的性质以及起重机的工作环境等因素来决定金属结构构件的许用应力。在设计过程中主要采用许用应力法来对桥式起重机桥架金属结构进行设计。首先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。在设计过程中参考了多种资料并且进行了实地考察,尽量利用各种条件力求能够更好的来完成此次设计。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,力求设计经济合理;通过采取参考前人的先进经验,力求能够有所创新；通过计算机辅绘图和设计计算都充分发挥计算机的强大辅助功能,力求使设计更加高效精准。
