【摘要】：随着现代工业化的快速发展,对起重机的要求愈来愈高,型号和种类越来越多,起重机的传统设计已经不能满足现代设计要求,急需一种新的设计理念,来满足安全性和实用性的要求。 传统起重机设计在结构力学和工程经验基础上进行设计的,随机性比较大,设计的起重机既笨重又不能保证其安全性,从而导致安全事故频发,给生命财产造成重大损失。 随着计算机技术的发展及有限元方法的运用,从而使复杂的工程问题得到了解决。本文以10T单梁式起重机为例,利用有限元方法和力学计算相结合,通过workbench软件对起重机整体进行静态及动态分析,计算出起重机在匀速起吊及突然急停等不同工况下的各部分的位移和应力变化,并得到相应的数据,通过查看这些数据,找出起重机的薄弱环节,对其进行优化设计,改进不合理之处。
[Abstract]:With the rapid development of modern industrialization, the demands on cranes are getting higher and higher, the types and types of cranes are more and more, the traditional design of cranes can no longer meet the requirements of modern design, and a new design concept is urgently needed. To meet the requirements of safety and practicality. The traditional crane design is designed on the basis of structural mechanics and engineering experience, which has a large randomicity. The designed crane is cumbersome and can not guarantee its safety, which leads to frequent safety accidents and great losses to life and property. With the development of computer technology and the application of finite element method, complex engineering problems have been solved. Taking 10T single beam crane as an example, the static and dynamic analysis of the whole crane is carried out by means of the combination of finite element method and mechanical calculation with workbench software. The displacement and stress changes of each part of the crane under different working conditions such as constant speed lifting and sudden stop are calculated, and the corresponding data are obtained. Through checking these data, the weak links of the crane are found out, and the optimum design of the crane is carried out. Improve the unreasonableness.
