MOBILE LOAD TEST VEHICLE

摘要

PROBLEM TO BE SOLVED: To enable a mobile load test vehicle to detect the vibration of a track or the ground with high accuracy by appropriately imparting a lateral pressure to the track. SOLUTION: A bearing 120 is supported on the truck frame 118 of a loading truck 15 through an axle spring 119 and a loading wheel 122 is fitted to the bearing 120 through an axis arm 121. Then a wheel load excitation device 123 which imparts a vertical load to the loading wheel 122 is mounted on the truck frame 118. At the same time, a lateral pressure exciting device 124 which imparts a load to the loading wheel 122 in the direction of the rotating axis of the wheel 122 is also mounted on the frame 118. The lateral pressure exciting device 124 imparts the load to the end section of the axis arm 121 toward a direction inclined to the track 17 side from the axial direction of the axis arm 121.
