Problems solved by technology

[0002] The bridge comprehensive inspection operation vehicle is to install the detection head at the end of the boom of the bridge inspection vehicle, extend to the bottom or side of the bridge, collect the surface data of the bridge and transmit it to the computer for data analysis and image recognition detection, and diagnose bridge diseases. , there have been some achievements in the research on the multi-body system of the rigid mechanical arm of the bridge inspection vehicle at home and abroad. It is more intense, and the dynamic model is more complicated. In order to realize the stable and high-precision trajectory tracking of the probe head, the influence of flexible deformation on the dynamic characteristics of the entire system cannot be ignored.
