Simulation of a freight wagon bogie in double roller test rig
Advances in Mechanical EngineeringTest benches are useful tools for testing bogies in laboratory conditions, most of which consist of large rollers to move the wheels of the bogies, either at a reduced scale or at full size. The full-scale test rig located at the BOGLAB laboratory uses two small rollers to move each wheel of one of the bogie’s wheelsets.

Finite-Element Modelling of Double-Roller Clamping Spinning of Wind Concentrator [PDF]
Frontiers in Energy Research, 2022 In order to improve the unit-power of a wind-driven generator, a wind concentrator with complex shape is installed in front of the impeller, which makes the airflow integrated and accelerated. It is important to manufacture the wind concentrator with high precision. The double-roller clamping spinning (DRCS) is a dieless, flexible spinning process that
