摘要
主要针对材料阻尼的测试技术方面进行实验,研究了测试技术对阻尼特性识别结果的影响。实验表明,边界条件和识别算法对阻尼比测量结果的影响显著,造成了阻尼测试的困难。针对此,提出了材料阻尼测试中引起误差的原因及其改进的建议。
Tested on a test measuring the damping technology, identified the intluence ot tectmotogy on the damping characteristics of the test results. Experiments show that boundary conditions and recognition algorithm make significant effect on damping test, create the difficulties in the damping test. The cause of the errors caused by the material damping test, and the suggestion for improvement are presented.
