摘要
在分析螺旋摆动液压缸的结构和工作原理的基础上,分别进行了螺纹牙型角为60°5、0°、40°、30°的两级螺旋传动Pro/E三维建模,通过Pro/E与ADAMS两个软件之间的专用接口程序Mechanism/Pro,将两级螺旋传动模型导入到ADAMS中,添加复杂约束和力,进行动力学仿真计算,模拟摆动螺旋液压缸的旋转过程。仿真结果表明:两级螺旋副运动可靠,无干涉;螺纹牙型角为50°螺旋传动的动态响应最为灵敏,螺纹牙型角为60°时的螺旋传动最为平稳。
The structural design and operation principle of rotary hydraulic cylinder are introduced.Using Pro/E software,double-helix transmission model for 60°,50°,40°and 30° thread angle are established.through the interface module Mechanism/Pro of Pro/E and ADAMS which defines rigid bodies, double-helix transmission model is introduced into ADAMS in which complex constraints and forces are added,Dynamics property of double-helix transmission are solved.Rotate process of Rotary hydraulic cylinder are simulated.The results show that double-helix transmission is reliable and no interference,dynamic response of double-helix transmission for 50° thread angle is the most sensitive,double-helix transmission for 60° thread angle is the most steady.
