集装箱装卸桥的模态参数识别

Model Parameter Identification of the Port Crane

针对集装箱装卸桥的结构特点 ,选用环境激励法对其进行模态参数识别 .阐述了测试技术与分析技术中的关键问题 ,对测试系统的合理组成、采样频率的设置、模态参数的正确识别进行了研究 ,并对桥吊进行了测试 。

According to the structural character of the port crane,natural excitation method is used to identify model parameters.This paper expounds the key point in this test,including the sound composition of the system,and the setting of sampling frequency,and the correct identification of the model parameters.And in the end the test result is obtained.
