Abstract
The coal transport trestle as a connection channel is widely used in large and medium-sized coal enterprises, which plays an important role in the whole manufacturing process. The vibration problems in coal transport trestle can not only reduce the occupant comfort, cause people serious harm, but also have pernicious effect on structure. Along with the structure aging and dynamics property change, things go badly, which even causes enormous life and property loss. This paper describes the vibration testing and analysis methods of the steel truss coal trestle though engineering examples. The results show that the belt transport system is the main reason which caused the vibration of the STCT, and trestle must undergo resonance phase with the exciting force changes.
