摘要
在振动试验测量技术研究中,提出了一种获取结构界面加速度阻抗的新方法——不测力法。通过设计带有集中质量块的圆筒结构试验件,对其进行了正弦扫描试验,获得了试验件的界面加速度阻抗,通过与有限元及测力法比较,验证了该方法的有效性。
In order to study how to acquire interface apparent mass of a structural piece in vibration test, a novel non-force-measured method is presented. Sine sweep vibration test of cylinder piece with appended mass was conducted and the interface apparent mass of the structural piece was acquired finally. Comparing the results of non-force-measured method with that of FEM and force-measured method, it is validated that non-force-measured method is reasonable and effective
