摘要:
受到超高空心薄壁墩身特性的影响,现有在超高空心薄壁墩身自由端对应的节点上动力关联较为复杂,传统超高空心薄壁墩身动力模型的分析结果局部参量分析不足,造成模型应力变化状况与实际偏差较大。为此,结合现阶段超高空心薄壁墩身结构及其多场耦合条件,对其动力特性模型展开优化分析。通过多场耦合下超高空心薄壁墩身动力分布模型;多场耦合模态分析;墩身动力特性模型计算;完成对多场耦合下超高空心薄壁墩身动力特性的全局优化。实验对比表明;经过优化后的模型,能够更为准确反映多场耦合下超高空心薄壁墩身动力特性,且在应力响应上表现更为优秀,稳定性更好,且兼具更优秀的动力分析能力。
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.
