【摘要】 地震对高层与高耸结构的破坏通常非常严重,且其破坏往往隐藏着潜在危险。先应用ANSYS有限元软件对某公司产的TC6010塔式起重机进行整体建模,并以此为基础对塔机进行模态分析,在施加宁河天津波后得到位移以及速度的响应,对获得的结果进行了初步的分析。由计算结果可知塔式起重机为低频振动系统容易引起结构共振,在地震波的作用下,塔式起重机塔机最先可能在起重臂产生破坏。更多还原

【Abstract】 Earthquake damages to the tall and towering structures are usually very serious,but these dangers are often hidden.The paper uses the finite element software Ansys to set up the overall modeling of the TC6010 tower crane which is produced by a company,and carry on the modal analysis based on it.The paper obtains the data of the displacement and the speed response of the complete machine after exerting the Ninghe Tianjin seismic wave,and has the preliminary analysis to the result.The results show that the tower crane is a low-frequency vibrating system and easy to cause the structure resonance,the crane tower may damage in the boom firstly under the action of seismic wave.更多还原
