摘要
通过调整力学参数,完成倒塔作业杆塔与周边建筑物碰撞情况分析,然而忽略了非线性单元的属性,导致分析结果不佳。对此,提出倒塔作业杆塔与周边建筑物实时动态碰撞风险仿真分析。结合质量矩阵以及位移矩阵等对非线性结构进行动力学建模,并引入有限弹性单元,对非线性结构属性进行表征。结合碰撞风险与量化结果之间的线性相关关系,构建出拥挤度以及接近度这2个风险指标。通过对碰撞风险指标进行分级处理,并将其映射为5种不同的预警等级,对碰撞风险值进行求解。实验结果表明:对实时动态碰撞风险进行仿真分析时,分析结果的理想拟合系数较高,具备较为理想的分析精度。
By adjusting the mechanical parameters,the collision analysis between the tower and the surrounding buildings in the tower collapse operation is completed,but the properties of the nonlinear elements are ignored,resulting in poor analysis results.In this regard,a real-time dynamic collision risk simulation analysis between the tower and the surrounding buildings in the tower collapse operation was proposed.Combined with the mass matrix and displacement matrix,the dynamic modeling of the nonlinear structure was carried out,and the finite elastic element was introduced to characterize the nonlinear structural properties.Combined with the linear correlation between collision risk and quantification results,two risk indicators of congestion and proximity were constructed.The collision risk value was solved by grading the collision risk index and mapping it to five different warning levels.The experimental results showed that the ideal fitting coefficient of the analysis results was high and the analysis accuracy was relatively good when the real-time dynamic collision risk was simulated and analyzed.
