The invention discloses a stable controllable load normal loading device, which comprises a basic frame structure, a power loading device, a gear transmission device, a regulation device and an auxiliary device, wherein the foundation bed of the basic frame structure is provided with a through hole through which a test specimen can pass; a first swallow tail sliding rail and a second swallow tailsliding rail, which are laterally arranged on the foundation bed, are positioned on two sides of the through hole; a stud laterally penetrates through a loading end plate, a first loading main base plate, a second loading main base plate, a buffer block clapboard and a buffer block end plate in sequence and is used for fixedly connecting the loading end plate with the buffer block end plate; the left end of a loading screw of the power loading device is fixed in a bearing pedestal, and the right end of the loading screw is screwed with the loading end plate; a motor cabinet is provided with agear motor; the output shaft of the gear motor is provided with a second cylindrical straight gear, and a first cylindrical straight gear and the second cylindrical straight gear are meshed; an adjustable final motion cushion foundation bed is fixed on the loading main base plate; a final motion cushion hole is positioned on the final motion cushion foundation bed; and the final motion cushion isfixed in the final motion cushion clamping hole through a gasket and a set screw.
Description
technical field [0001] The invention relates to the technical field of fatigue test equipment, and relates to a stable controllable load normal loading device. Background technique [0002] The phenomenon of fretting fatigue exists in various fields, and it is difficult to detect, which greatly reduces the fatigue life of structural parts, causing the failure time to be much lower than the expected life. Fretting is a complex loss process, which is subject to the interaction of wear, corrosion and fatigue. [0003] The main factor causing fretting fatigue cracks is fretting friction, which often occurs in the fretting area and the periphery of the fretting area affected by fretting friction; different from ordinary mechanical fatigue, the cracks caused by component fretting fatigue do not appear If the influence of fretting friction is neglected at the stress concentration part or the dangerous section position of the part, the actual service life of the component will be s...
