摘要:
为了在设计时确定塔式起重机臂斜拉杆的合理位置和机臂悬挂重物荷载的不利位置，针对某型塔式起重机，运用有限元软件对起重臂进行强度与刚度的结构分析.对于不同的拉杆位置和载荷位置，建立了有限元力学模型，加载并求解得到位移和应力云图，将计算结果与许用挠度和许用应力作对比，得到合理的位置参数.结果表明合理的斜拉杆位置：为短拉杆和长拉杆分别与上弦杆交汇在13.125 m左右和51.875 m左右,改变斜拉杆的位置可以提高起重臂的强度与刚度;荷载的不利位置区段为施加在下弦杆端部56.25 m附近至最远端，起吊较重物料时应尽量避免长时间处于此区段，采用局部加强的方法可以提高起重臂的强度与刚度.
Abstract:
To determine the reasonable positions and the dangerous positions for the loads of tower crane′s tension rod in the stage of design,a finite elements software was applied to analyze the strength and stiffness for a kind of crane boom.Displacement nephograms and stress nephograms were obtained after building finite elements models,loading and solving for different positions of tension rod and loads.Rational position parameters were acquired by comparing the nephograms with allowable deflection and stress.The results show that rational positions of the short rod and the long rod intersecting with the top chord are in about 13.125 m and 51.875 m;the properties of strength and stiffness are enhanced by changing the positions of the rods;the dangerous positions for loads on bottom chord are from about 56.25 m to the end,which means that it must be forbidden when the tower crane′s tension rod works at the interval with heavy loads for a long time.The properties of strength and stiffness are improved by locally reinforcing.
