为了确定塔机安全合理的附着间距,提出了一种塔机附着装置的刚度计算方法,从而确定了该类附着装置刚度的强弱方向,并按照刚度最弱方向的刚度确定塔机附着间距。计算得到附着装置刚度后,折算成与塔机结构有关的弹性附着系数,运用传递矩阵模型缩减法求得的超单元刚度阵的行列式,可得到不同弹性系数下的最佳附着间距,并通过有限元分析软件验证了计算的正确性和有效性。
In order to determine the safe and reasonable attachment distance of tower crane, a stiffness calculation method of tower crane attachment was proposed to determine the strength and weakness of this type of attachment, and the attachment pitch of tower crane was determined according to the stiffness of the weakest stiffness. After calculating the stiffness of the attachment, it is converted into the elastic attachment coefficient related to the structure of the tower crane. By using the determinant of the transfer matrix model to reduce the stiffness of the super element, the optimal attachment pitch under different elastic coefficients can be obtained and passed Finite element analysis software verified the correctness and validity of the calculation.
