其次，对液压抓斗装置掘削抓取岩土的数学模型进行研究。
Secondly, geotechnical excavation mathematical model of the mechanism of hydraulic grab is studied.
依据振动掘削的动力学特征和振动机理，建立铲斗-土壤的单自由度模型。
The single degree of freedom model of bucket-soil was established according to the dynamic characters and vibratory mechanism.
通过振动铲斗激振力及检测铲斗工作状态下的加速度或位移，利用合适算法能够较好地辨识出被掘削土体参数。
According to the vibratory force, acceleration or displacement of the bucket, which are measured in working state, the reasonable identification algorithm of soil parameter is also presented.
