The analysis of dynamics characteristic for JJ160/41-K type derrick
【摘要】 运用I DEAS软件 ,以简化的空间梁单元建立计算机FEM模型 ,对JJ160 /4 1 K型钻机井架进行了设计载荷下的动力特性分析。通过对比现场测试结果 ,建立了JJ160 /4 1 K型井架的动态特性评价准则
【Abstract】 In this paper, the author establishes the computer numerical model to calculate mechanical parameters with I-DEAS software by adopting simplified three dimensional beam element as the basis element for FEM and analyzes dynamic characteristic for JJ160/41-K type derrick under the design loading.In contras with on-site testing result, the evaluation rule of dynamic characteristic for JJ160/41-K type derrick is established.
