Test bench history

- Nov 30, 2017 -

As early as 1957, Japan Railway Technology Institute equipped with locomotive rolling test stand, and the use of eccentric wheel to achieve sine wave excitation. This is a two-axle half-car test bed that has been in operation for more than 30 years and plays an important role in many research and development projects such as preventing derailment of trucks, regenerative braking and bolsterless bogies. After 1987, it started to build a more complete vehicle rolling table and realized the horizontal excitation of two coaxial rollers. The eccentric was still used in the vertical direction and was built in 1991.

France Vitry (Vitry) The test rig was CAFL in 1964 built the company, enabling coaxial vertical and horizontal lateral roller movement, and the use of simple hydraulic control. The test rig can test the vertical, horizontal and oscillating vibration frequency, amplitude and resonance of rolling stock, especially the relationship between the vertical and horizontal excitation force changes due to impact and the running of rolling stock, Study on the safety and stability of walking.

Berlin, Germany Before 1967, the East Germany also built a rolling test stand in Berlin, where it can be used for setting and acceptance testing of rolling stock and springs, braking systems and power plants.
