| 1 | 考虑摩擦因素影响的结合面切向接触阻尼分形预估模型及其仿真显示文摘为准确计入结合面表面微观形貌对结合面的影响,提出结合面的'固-隙-固'接触模型。基于该接触模型和接触分形理论以及赫兹理论,建立考虑摩擦因素影响的结合面切向接触阻尼的分形预估模型,并通过数值仿真研究揭示有关参数对结合面切向接触阻尼的影响,为后续结合面动力学建模和动力学特性分析做准备。仿真分析结果表明:结合面的切向接触阻尼随结合面实际接触面积的增大而增大;随结合面法向载荷的增大而减小;随结合面间摩擦因数的增大而趋于恒定;实际接触面积影响cte*-μ曲线转折点(即临界摩擦因数μc)的位置,随着实际接触面积的增大,临界摩擦因数μc亦同时增大;不同的分形维数取值,尤其是分形维数取值在临界值(D=1.55)的两侧时,结合面间的接触行为存在较大差异。 | 李小彭 王伟 赵米鹊 聂慧凡 闻邦椿 | 2012 | 机械工程学报2012，48，23： | 33 |

| 3 | Modeling and Analysis of Mechanical Quality Factor of the Resonator for Cylinder Vibratory Gyroscope显示文摘Mechanical Quality factor(Q factor) of the resonator is an important parameter for the cylinder vibratory gyroscope(CVG). Traditional analytical methods mainly focus on a partial energy loss during the vibration process of the CVG resonator, thus are not accurate for the mechanical Q factor prediction. Therefore an integrated model including air damping loss, surface defect loss, support loss, thermoelastic damping loss and internal friction loss is proposed to obtain the mechanical Q factor of the CVG resonator. Based on structural dynamics and energy dissipation analysis, the contribution of each energy loss to the total mechanical Q factor is quantificationally analyzed. For the resonator with radius ranging from 10 mm to 20 mm, its mechanical Q factor is mainly related to the support loss, thermoelastic damping loss and internal friction loss, which are fundamentally determined by the geometric sizes and material properties of the resonator. In addition, resonators made of alloy 3J53(Ni42Cr Ti Al), with different sizes, were experimentally fabricated to test the mechanical Q factor. The theoretical model is well verified by the experimental data, thus provides an effective theoretical method to design and predict the mechanical Q factor of the CVG resonator. | XI Xiang WU Xuezhong WU Yulie ZHANG Yongmeng | 2017 | Chinese Journal of Mechanical Engineering2017，30，1： | 3 |
