摘要
在ANSYS WORKBENCH环境下对海洋平台抓管机进行整体参数化建模,通过改变主臂、折臂的工作角度,获得多工况下折臂抓管机的工作姿态。在进行结构分析时,对任一工作半径下折臂抓管机垂直起吊路径进行工况抽样,考虑环境载荷、吊臂自重、额定工作载荷,对折臂抓管机整体进行有限元强度分析,获得多工况下关键零件及关键节点的应力应变分析结果。实现了折臂抓管机整体强度分析的快速高效计算。
Parameterized-model was established for the whole knuckle boom pipe crane of offshore platform by ANSYS WORKBENCH ,and multi-attitudes was obtained by changing the boom and knuckle boom lifting angle.During the analysis of structure,some attitudes of the knuckle boom pipe crane on any lifting radius were sampled to calculate entire strength by considering environ-mental loads,boom weight,rating load to achieve stress and strain results of all key parts and nodes by finite element analysis.A quick-efficient analysis of entire strength for knuckle boom pipe crane was achieved.
