Clamp tool for assisting high-frequency dynamic stiffness detection experiment of railway fastener

Abstract

The utility model relates to a clamp tool for assisting a railway fastener high-frequency dynamic stiffness detection experiment, which comprises a similar steel rail, a similar sleeper and a fastener structure, and the similar steel rail is clamped on the similar sleeper through the fastener structure; the similar steel rail comprises a base section, a first trapezoidal section, a second trapezoidal section and a rectangular section from bottom to top, the bottom of the first trapezoidal section is connected with the base section, the bottom of the second trapezoidal section is connected with the top of the first trapezoidal section, and the rectangular section is connected with the top of the second trapezoidal section. The inclination angle of the side edge of the first trapezoid section is smaller than that of the side edge of the second trapezoid section. Compared with the prior art, the device has the advantages of high fastener system dynamic stiffness detection frequency, convenience in processing and mounting, wide application range and the like.
