| 摘 要： | 根据基础激振-共振质量法测试原理设计专用的实验测试系统，对作为高速旋转引信实验机减振部件使用的新型锰铜合金圆环类部件进行动力学特性测试。获得测试对象的刚度系数、阻尼系数以及损耗因子等动力学特征参数值与使用频率、作用力幅值以及合金厚度之问的对应关系。从微观晶粒运动角度，结合应力、应变以及振动能量等特征值变化，对获得的新型锰铜合金环类部件的测试结论进行理论分析。通过实验测试得出新型锰铜合金适合作为高速旋转设备减振部件的结论。

| Abstract: | On a so-called base Excitation-Resonance mass method, a proper experimental set is designed. The dynamics characters of axis sleeve made of the new Mn-Cu alloy is investigated, which is used as absorber in the high-speed rotary fusee-testing machine. The relationship between stiffness, damping coeflqcient dissipation factor and frequency, and acting force is acquired. Based on the crystal microstructure of the Mn-Cu alloy, the test results are analyzed theoretically in correspondence with the stress, strain and energy change. It is concluded that the new Mn-Cu alloy is feasible to be used as absorber in the high-speed rotary fusee-testing machine by the experiment. |
