隧道检测车的动力性能分析

Analysis of Dynamic Response of Tunnel Inspection Car

使用有限元方法建立隧道检测车车体的力学模型并对其进行了模态和动力响应分析,得出了构架上测量装置的动力响应特点,结果有助于改进检测车的设计以及对检测车测量数据进行误差分析和修正。

In this paper, with the application of the finite element method, the mechanics model of the carbody of the tunnel inspection ca is set up, and the modal and dynamic response analysis of the model are carried out, the response characteristics of the measuring devices othe truss, which are helpful for the improvement on the design of inspection car as well as for error analysis and correction of the data mea sured by the inspection car, are obtained.
