BMT-S/BOJI – SERVO HYDRAULIC BOGIE TEST MACHINE, STATIC COMPRESION TEST
BESMAK BMT-S/BOJIE Series Servo Hydraulic Bogie Compression Test Device has a body structure specially designed for bogies and is produced in accordance with standards. The system has a servo hydraulic structure. Force measurement and control is carried out via a load cell. The servo hydraulic actuator, which has a double-acting structure specifically for bogie pressing applications, is positioned on the upper side of the high-rigidity test body. The loading head of the actuator is produced in a mechanical spherical structure suitable for the bogie base.
The test system also allows position-controlled applications through the position sensor embedded in the actuator. Thanks to the application-specific infrastructure of the system, it can perform force control, displacement control, user-defined stepwise loading with force or displacement control, and constant load waiting applications. Thanks to the force measurement system placed under the bogies, if requested, the loads applied to each of the wheels of the bogies can be measured and the deformations at the end of the bogie construction can be measured.
