主要研究Mn-Cu系及Cu-Zn-Al合金的阻尼性能与力学行为的关系,并探讨了受力条件对阻尼性能的影响。 试验表明,此类合金的阻尼能力与振动中的受力状态有较强的依赖关系。经适当热处理后可得到较高的阻尼性能。
The relationship between damping properties and mechanical behavior of Mn-Cu and Cu-Zn-Al alloys is mainly investigated. The influence of stress conditions on damping properties is also discussed. Experiments show that the damping capacity of these alloys has a strong dependence on the state of stress in vibration. After the appropriate heat treatment can get a higher damping performance.
