Application Of Vibration Measurements And Finite Element Model Updating For Structural Health Monitoring Of Ballasted Railtrack Sleepers With Voids And Pockets, Sakdirat Kaewunruen, Alexander Remennikov

Alex Remennikov

Although vibration measurements are very useful and common in practice nowadays in many applications related to mechanical, civil, and aerospace engineering, the utilisation in railtrack infrastructure and facilities is not widely established. This chapter deals with the application of vibration measurements and finite element model updating to the assessment of ballasted railtrack sleepers, in particular with a void and pocket condition. It describes the concept of vibration measurements and the understanding into the dynamic behaviour of ballasted railtrack sleepers. It discusses briefly on the development of finite element model of in-situ sleeper and its updating. Then, the application to structural …
