多场耦合下超高空心薄壁墩身动力特性优化模型
Optimized Model for Dynamic Characteristics of Ultra-high Hollow Thin-walled Pier Under Multi-field Coupling
摘要
Abstract
Influenced by the characteristics of the ultra-high hollow thin-walled pier,the dynamic correlation at the existing nodes corresponding to the free end of the ultra-high hollow thin-wall pier is relatively complex.The analysis results of the traditional dynamic model of the ultra-high hollow thin-walled pier show an insufficiency of analysis on part of the parameters,which results in a large deviation between the stress change of the model and the actual situation.Therefore,given the ultra-high hollow thin-walled pier structure at the present stage and its multi-field coupling conditions,optimization analysis of its dynamic characteristic model was carried out.Through the dynamic distribution model of the ultra-high hollow thin-walled pier under multi-field coupling,multi-field coupling modal analysis and pier dynamic characteristic model calculation,the overall optimization of the dynamic characteristics of the ultra-high hollow thin-walled pier under multi-field coupling was completed.The experimental comparison shows that the optimized model can more accurately reflect the dynamic characteristics of the ultra-high hollow thin-walled pier under multi-field coupling,and has better stress response,stability,and dynamic analysis ability.关键词
