FIELD: machine building. ^ SUBSTANCE: machine consists of power frame made in form of base and upper cross bar connected with poles, of grippers for sample securing, one of which is connected with drive, of force sensor connected to one of grippers, of sensor of sample lengthwise deformation and of measurement and control systems. One of the grippers can travel in axial direction under effect of test load and is connected with a spring link counter to this travel. The force sensor and drive of the movable gripper are coupled with a back tie so, as to continuously maintain load on the sample by means of periodic tightening of the spring link. ^ EFFECT: upgraded accuracy, versatility and expanded functionality of machine. ^ 3 dwg |
