运用ANSYS软件,建立了TC2400型塔带机的有限元模型,对其在两种运行方式下的4种不同工况进行了整体结构刚度和强度分析;为了得到更精确的应力解,还对极端工况下工作平台、回转平台与塔身之间销轴连接、塔节之间高强螺栓连接等多个关键部位建立了子模型,并进行了强度校核。 Using ANSYS software, the finite element model of TC2400 tower crane was established, and its overall structural stiffness and strength analysis were carried out under four different operating modes under two different operation modes. In order to obtain more accurate stress solution, Under the conditions of the working platform, the pivoting platform and the tower between the pin connection, the tower between the high-strength bolts and other key parts to establish a sub-model, and the strength of the check.
