Spline couplings are widely used in transmission systems to transfer torque due their higher load carrying capacity and better durability performance. Most researches conducted under static quasistatic loading cases; however, very little is known about contact behavior stress distribution dynamic cases, especially as a key component between wheel axle. In this paper, 3D impact analysis model of...

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

Rigid pavements are often preferred to flexible types due their higher durability and ease of maintenance also reduce early road failure increase its longevity. This study redesigned a deteriorated segment Oke-Omi pavement as rigid pavement. The thickness was derived using the American Association State Highway Transportation Officials (AASHTO) design method. A programme spreadsheet developed f...

A common mobile robot design consists of three ‘omniwheels’ arranged at the vertices of an equilateral triangle, with wheel axles aligned with the rays from the center of the triangle to each wheel. Omniwheels, like standard wheels, are driven by the motors in a direction perpendicular to the wheel axle, but unlike standard wheels, can slip in a direction parallel to the axle. Unlike a steered ...

Buried culverts have been in service more than half a century and their age raises questions about reliable serviceability for the new standard vehicles. The gross weight axle spacing of these trucks play an important role on performance buried where culvert is covered with shallow fill heights. Field live load tests were conducted by driving loaded truck over some at slow speed while recording...
