千噸級分離塔吊裝的有限元分析與試驗(yàn)研究
[Abstract]:In view of the large-scale hoisting project, the structural stress testing technology is introduced to realize the real-time monitoring of the structural stress change state, which provides powerful and timely data support for the actual hoisting process. Taking the first lifting project of 4000 ton crawler crane as an example, the skirt structure of the suspended equipment is designed and analyzed by finite element method. In the actual hoisting process, the stress testing technology is introduced to test the stress of the reinforced part. Compared with the finite element results, the rationality and credibility of the finite element method and the test results are verified, and the results are discussed at the same time. Data support is provided for the further improvement of structures and institutions. With the introduction of stress testing technology, the change state of structural stress can be obtained in real time, which provides data support for the site conductor, and is convenient to judge the command correctly.
