Reaction structure for a testing machine

Abstract

【Item Uses】 This design comprises a set of reaction units for a testing machine used in conjunction with a testing machine for testing test subjects. For example, one end of the test subject can be fixed to this reaction unit, and the other end of the test subject can be displaced by a stress-applying part that applies mechanical stress and is located close to the reaction unit, thereby performing fatigue testing on the test subject. The stress-applying part can, for example, be a triaxial actuator capable of simultaneously and independently applying static or dynamic displacement in the X, Y, and Z directions (i.e., orthogonal three directions). Referring to Figure 1, which shows the back, left side, and top, it can be seen that the movable part at the top of this design can move back and forth on the base along the groove provided on the base. Referring to Figure 2, which shows the front, left side, and top, it can be seen that the mounting plate provided on the front side of the movable part can move up and down on the front side of the movable part along the plate moving mechanism provided on the movable part. 【Design Description】 Perspective 1 shows the front, left side, and top views. Perspective 2 shows the back, left side, and top views. The design features include: as seen in the perspective and front view, the mounting plate has an approximately elongated oval hole in the center; as seen in the perspective and rear view, the movable part has a compartmentalized shape on its back; as seen in the left and right views, the movable part has an approximately inclined shape on its left and right sides; and as seen in the perspective, left, and right views, the base has compartmentalized shapes on its left and right sides. These features combine to create a design with a unique visual effect.
