Abstract
PURPOSE: To miniaturize a unit and also to reduce its manufacture cost by arranging respective support members of a tester so that force will operate only in the axial direction of each support member without bending moment.
CONSTITUTION: Tubes 5 and 6 are set and cylinder unit 13 is operated. At this time, a bending load is denoted by 2F1 and tensile force F2 operates on upper connecting levers 16 and 18. On reaction frames 8 and 9, force of F3=F1/2 from tubes 5 and 6 operate through support blocks 28 and 29 of tubes 5 and 6. Then, tensile force F2 is divided into F4=F1/2 and F5, which are equal in value and opposite in direction. As a result, no bending force operates upon reaction force frames 8 and 9, and consequently bending force never operates upon beams 1W4 of the unit, so that part of compressive force F5 applied to connecting beam 11 will be born. In this way, only axis force operates on the connecting lever and connecting beam, so that there will be no need to provide a large frame.
