Identification Damage of Rail Bridge Components Using Drone

Building Identification Using Ar. Drone

Quadcopters have grown immense popularity in the recent times in various fields of active research since they have huge potential in search and rescue operations, sports and autonomous tracking. One of them is to understand the terrain and identify its location in GPS denied environment. In this project we propose a novel Building detection method in the terrain of IIT Kanpur. Training data is ...

Rail Damage Potentials of Sloshing Cargo

In this paper a two-degree-of-freedom model representing the sprung mass and the sloshing cargo in a vehicle is proposed to study the dynamic interaction of a sloshing cargo and the carrying vehicle, to simulate the dynamic wheel forces on the rails as a result of lateral perturbations derived from turnings along the railway path and the resultant cargo sloshing. The use of the Fourth- and T...

Vibration of Train-Rail-Bridge Interaction Considering Rail Irregularity with Arbitrary Wavelength

A generation method for the rail random irregularity with arbitrary wavelength interval (WI) is developed, and its accuracy and efficiency are demonstrated. Then a moving wheel-rail-bridge interaction element is derived to establish the finite element equations of motion for the train-rail-bridge interaction system, and the flow chart of assembly and calculation for the system equations is give...

Eddy Current Rail Inspection Using AC Bridge Techniques

AC bridge techniques commonly used for precision impedance measurements have been adapted to develop an eddy current sensor for rail defect detection. By using two detection coils instead of just one as in a conventional sensor, we can balance out the large baseline signals corresponding to a normal rail. We have significantly enhanced the detection sensitivity of the eddy current method by det...
