摘要

目前，我国井径测井仪推靠臂采用偏心圆弧线型，其存在动载荷大、传力效果差、仪器寿命短等问题。针对以上问题，对推靠臂采用渐开线、阿基米德螺旋线和偏心圆弧线3种结构方案进行参数化设计，并对3种推靠臂凸轮运动特性及机械效率进行了分析研究。分析得知，分动式推靠系统中采用渐开线型推靠臂结构能大大改善活塞杆的受力特性，减少摩擦磨损，进一度提高测量精度。运用ADAMS/View模块建立3种分动式推靠系统打开、测量模型，设置初始参数并进行运动仿真；得出了3种运动状态活塞杆的运动轨迹曲线，验证了其运动规律，为井径测井仪结构优化设计、改善性能提供了理论依据。

Abstract

At present，the domestic caliper logging tool adopts an eccentric circular arc type in the pushing arm， which has the problems of large dynamic load， poor force transmission effect， and short instrument life. In order to solve the above problems， the three kinds of structural schemes of involute， Archimedes spiral and eccentric circular arc are used for parametric design of pushing arm， and the three kinds of pushing arm cam motion characteristics and mechanical efficiency are analyzed. The analysis shows that adopting the involute pushing arm structure in the split pushing system can greatly improve the force characteristics of the piston rod， reduce the friction and wear， and further improve the measurement accuracy. The ADAMS/View module is used to create three types of split pushing systems to open and measure models， the initial parameters are set and motion simulation is performed. The trajectory curves of piston rods in three motion states are obtained， and their motion laws are verified， which provides a theoretical basis for the optimal design and performance improvement of the structure of caliper logging tool.
