Design of rail vehicle weighting system using pressure sensor

초록

A mechanical system to detect the static wheel weight of the railway bogie using hydraulic pressure has been designed. Wheel weight can be acquired by a pressure sensor mounted on the hydraulic pressure distributor and displayed by a wheel load indicator with a resolution of 0.1 KN when the hydraulic pressure induced from the hydraulic hand pump lifts a wheel by mechanical components connected with the hydraulic pressure cylinder. The measurable wheel load is 100 KN. Also, a height indicator which is attached on the wheel using a magnet shows the elevated height of the wheel from the rail.
