斜齿轮啮合过程齿根应力的实验研究

Jixie chuandong, 1994
本文提出了一种可用于测量斜齿轮副啮合过程击根应力和变形的静态加载实验装置，给出了实验台设计程序。按文中所提设计原理及程序可方便地设计出不同斜齿轮参数的静态加载实验台。文中以一对斜齿轮副为例详细测量了齿轮副在啮合过程中击根应力沿齿向分布及齿宽各截面的应力波形，并与计算结果进行了对比分析。

自复位双肢剪切型耗能段的滞回性能与力学模型

Jianzhu Gangjiegou Jinzhan
基于双肢短剪切型耗能段的耗能机制、形状记忆合金（shape memory alloy， SMA）棒材的超弹性特性和碟形弹簧的恢复力特性，提出了一种自复位双肢剪切型耗能段（self-centering coupled shear link， SC-CSL），该耗能段可有效提高中心支撑钢框架结构的抗震性能和震后恢复能力。采用校正的有限元法对SC-CSL的力学性能进行分析，研究其滞回性能和破坏模式；随后对考虑了SMA棒材直径和碟形弹簧刚度的10个模型进行了参数分析。结果表明：SC ...
