Simulation of an instrumented ultrasonic test run with a rail inspection train

Rail inspection performed by ultrasonic rail inspection trains is a complex and challenging process. A large number of variables and parameters given by the environment, the track and the testing-system have an influence on the overall performance of the inspection and the inspection result. Typically the parameter vary in a combination depending on the track condition. To evaluate the individual influence of each relevant variable, simulation tools can be used. Therefore the entire inspection process has to be transferred into a model using combined modelling techniques. The goal of this work is to model an instrumented ultrasonic test run with a rail inspection train with the parameters varied by a script over a virtual driven distance.
