Evaluating Track Endurance and Reliability

Actual Size Track Simulation Evaluation Actual Size Track Testing System

This system allows loading to be placed on a single 20 m test track (10 m
Number of Loading Units Vertical : 8 units
on a concrete base, 10 m on earth tanks) from above and below, and left (Actuators) Horizontal : 4 units
and right. A total of 12 electric hydraulic servo actuators, used to provide Vertical Dynamic : 125 kN
vibration, are fixed to movable gate-shaped loading units in four groups, Max. Load Static : 160 kN
(Per loading unit) Horizontal Dynamic : 65 kN
each group comprising two actuators loaded in a vertical direction (each
Static : 80 kN
on the left and right rails) and one in a left-right direction (on one of the
Max. Vibration Amplitude Vertical/horizontal ±50 mm
rails), respectively (on the same cross-section in regard to the longitudinal
0 to 35 Hz
direction of the rails being tested). These actuators remove phase
Frequency of Vibration Applied Sine waves can be superimposed at up to
difference and place load on the rails. 100 Hz.
Four groups

Two actuators in a vertical direction
on the left and right rails

One actuator in a left-right direction
on one rail
