Abstract

The invention relates to a fatigue and strength test table of a wind-power blade material. The fatigue and strength test table comprises a base, a main frame and a double-piston rod cylinder, wherein the main frame is arranged on the base; the top end of the double-piston rod cylinder is hinged on an upper cross beam of the main frame and is provided with a position sensor; one ends, extending downwards, of the piston rods of the double-piston rod cylinder are sequentially connected with a force transferring piece and a transition joint in sequence; a force sensor is arranged between the force transferring piece and the transition joint; an H-shaped test piece is connected with the transition joint by a pin shaft; an inner frame is fixed in the main frame and is provided with a vertical sliding matching mechanism and a horizontal sliding matching mechanism; the transition joint is arranged on the vertical sliding matching mechanism and the horizontal sliding matching mechanism and is suitable for vertical and horizontal free sliding; the H-shaped test piece is fixed on a supporting frame arranged on the base in a two-point simply-supported manner; and a displacement sensor and theforce sensor are connected with a controller which is connected with a display device used for displaying the displacement measured by the displacement sensor and the tensile force and pressure values measured by the force sensor.

Description

technical field [0001] The invention relates to the technical field of fatigue test and strength test equipment for standard test pieces made of wind power blade materials, in particular to a fatigue and strength test bench for wind power blade materials. Background technique [0002] In the prior art, there is a lack of equipment for performing fatigue tests and strength tests on standard test pieces made of wind turbine blade materials, and there is also a lack of relevant industry standards. Therefore, how to provide a fatigue and strength test device for wind turbine blades with high reliability to achieve the purpose of the experiment is a technical problem in this field. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fatigue and strength test bench for wind power blades with simple structure and high reliability. [0004] In order to solve the above-mentioned technical problems, the present invention pr...
