COMPOSITE LOADING TESTING DEVICE

PROBLEM TO BE SOLVED: To provide a composite loading testing device capable of loading simultaneously each load of torsion bending and an axle load with a simple structure, and capable of also loading independently and individually. SOLUTION: In this load testing device, each loading test of the torsion, bending and axle load is performed by applying the load to one end 10A of a test specimen 10 having the other end fixed to a device frame 1. The device is constituted so that the load test is performed simultaneously by providing a loading point 7 where each actuator 3, 4, 6, 11 on which each load of the torsion, the bending and the axle load is loaded is concentrated. Hereby, each load of the torsion, bending and axle load can be loaded simultaneously by the combination of a simple structure frame and each actuator. COPYRIGHT: (C)2004,JPO
