Problems solved by technology

According to Newton's second law F=ma, when the moving mass is constant, the moving acceleration can only have a certain value. After the existing vibrating table reaches the limit acceleration, it cannot achieve further improvement. This poses a difficult problem, namely: In the case that the acceleration of the table cannot be further increased, how to make the DUT installed on the moving coil get the acceleration value as large as possible

Embodiment Construction

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and a preferred embodiment.

[0020] refer to figure 1 Shown is a preferred embodiment of the invention, which relates to a device for generating high accelerations comprising a jig support 2 , a sliding sleeve 3 and a jig 4 .

[0021] Wherein, the fixture supporting body 2 is used to be fixedly connected with the moving parts of the vibration test equipment, especially the working table.

[0022] In order to ensure the accuracy of the vibration test, the aforementioned fixture support body 2 is preferably a cylindrical member, especially a cylinder, and when the fixture support body is fixedly connected to the work surface, the axis of the fixture support body should coincide with the axis of the work surface .

[0023] Further, several shafts are arranged symmetrically on the fixture supporting body 2 , and at least one sliding sleeve is shea...

Abstract

The invention discloses a method and device for generating high accelerated speed. The method comprises the following steps: fixedly connecting a clamp bearing body to a motion part of vibration test equipment, symmetrically arranging at least two shaft bodies on the clamp bearing body, enabling a shaft line of any shaft body to be vertical to a vibration direction of the vibration test equipment, arranging at least a sliding sleeve on any shaft body, enabling any sliding sleeve to move along the corresponding shaft body, and locking the selected position of any sliding sleeve on the corresponding shaft body according to the vibration test need, wherein a test piece is fixedly connected to any sliding sleeve through a clamp. According to the method, a test piece clamp structure is improved, so that the acceleration value of the test piece can be increased by 10-30 times by resonance of the clamp and a moving coil, wherein the resonant frequency can be changed by adjusting the vibration position of the clamp only. The device is simple in structure, superior in performance, easy, convenient and controllable to operate and low in cost, and has a wide application prospect in the technical field of vibration tests.

Description

technical field [0001] The invention relates to a high acceleration generating device, in particular to a method and a device for generating high acceleration, which can be applied in the technical field of vibration testing, especially in vibration testing equipment as an energy amplifying device. Background technique [0002] The electric vibration table is the most common vibration test equipment in the vibration test equipment. The vibration of the moving coil outputs a vibration force, and the vibration force is F=BLi. The higher the magnetic induction intensity B in the air gap, the longer the wire length of the moving coil is L The longer it is, the greater the current i input to the moving coil is, the greater the vibration force output will be. According to Newton's second law F=ma, when the moving mass is constant, the moving acceleration can only have a certain value. After the existing vibrating table reaches the limit acceleration, it cannot achieve further impr...
