摘　　要：介绍了一种新型的双螺旋摆动液压缸及其工作原理,运用三维建模软件Pro/E建立了双螺旋摆动液压缸的三维装配模型,并通过有限元分析软件Ansys-Workbench对关键部分两级螺旋副进行了有限元模型的建立及静力学仿真,通过仿真计算和理论计算的比较验证了模型的正确性,进而分析了不同的工作压力条件下螺旋副摩擦系数、螺纹线数等螺纹参数的变化对液压缸输出扭矩以及螺纹应力的影响关系,对实际工况下的摆动油缸参数的选择和结构的设计具有一定的参考意义。A new kind of double-helix rotary cylinder and it’s working principle is introduced.The 3D assembly model of the double-helix rotary cylinder is established in Pro/E.The finite element modeling and the static structure analysis of the key part,double helix pair,is carried out by finite element analysis software-Ansys-Workbench.The model is proved to be correct.The influence and relation on output torque of the cylinder and screw thread stress by different pressure,friction coefficient and the number of thread are analyzed,which provide reference for parameters choice and structure design of the rotary cylinder.
