半径杆
radius bar
- 在此基础上，进行了超磁致伸缩刀杆变形性能试验，获得了镗刀切削半径增量与线圈控制电流之间的关系曲线，验证了超磁致伸缩刀杆的可控性和稳定性。
A series of tests on the deformation behaviors of giant magnetostrictive tool rod were done, and the relation curve between the radios of boring cotter and the coil currents was obtained, which validated the controllability and stability of the radios of boring cutter. - 摘要文章以薄壁曲杆理论为基础，合理地假设了三个剪力滞翘曲位移函数，应用能量变分法推导出考虑曲率半径影响、弯、扭、剪力滞耦合的曲线箱梁弹性控制微分方程及其边界条件，为薄壁大曲率箱梁剪滞效应建立了理论分析基础。
Based on the theory of thin-walled curved bar, reasonable hypothesized a third-ord parabolic curve, the paper adoptes variational method on energy, taking the coupled relationship of the effect of curvature radius, bend, torsion and shear-lag into consideration, establishes the elastic governing differential equation and boundary conditions for thin-walled curved box girders, which set the foundation of theoretical analysis of shear-lag effect in thin-walled curved box girders. - 摘要就《机械原理》课程的某些内容（如：拆杆组的方法、矢量方程图解法的解题步骤、运动分析解析法的版本和方法、连杆机构的反转法设计、极位夹角、凸轮机构设计公式、组合机构的分类、齿轮齿顶圆半径公式、机械的平衡等）的取舍和叙述进行探讨，提出一些新的看法。
The acceptability our rejection and the depiction of some content in the course "Mechanisms and Machine Theory" is discussed, (e. g., group dividing, solving steps of the graphical method for vector equation , versions and methods for analytical kinematic analysis, inversion design for linkage mechanisms, crank angle between the two limiting positions, design formulae for cam mechanisms, classification of combined mechanisms, formula of the radius of addendum circle of gear, , balancing of machinery, etc.) and some new opinions are presented.
