Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] The present invention as figure 1 As shown, the section at A-A is shown as image 3 As shown, it includes the left support 1 and the right support 5 connected by the connecting cylinder 2, the bottom of the two supports is provided with lugs, the right end opening of the right support 5 is sealed by the cover plate 7, and the right end opening of the right support 5 is connected with the cover plate 7 is connected by the second screw B1. There is a resonant beam 3 with a rectangular section in the center of the connecting cylinder 2. The resonant beam 3 is a single rectangular beam. The ratio of the section height h to the width B can be selected according to actual needs, for example, the aspect ratio can be selected as 2:1. The left end of the resonant beam 3 is connected to the left support, and the long side of the rectangular section is perpendicular to the bo...

Abstract

The invention provides a standard sample for verifying the vibration testing capacity. The standard sample is connected with a left support and a right support through connecting barrels, and an opening of the right end of the right support is sealed by a cover plate. A resonance beam with a rectangular cross section is arranged at the center of each connecting barrel, the left end of the resonance beam is connected with the left support, and the long side of the rectangular cross section is perpendicular to a support bottom plane. The right end of the resonance beam is connected with a square mass block, the square mass block extends out of the cover plate, the side of the square mass block is parallel to the side of the resonance beam, and an upper plane is parallel to the support bottom plane. Due to the fact that the adopted fixing supports are provided with installing convex lugs, and vibration characteristics of a vertical table and a horizontal sliding table are respectively verified during testing. In addition, compared with existing standard samples, the standard sample is small in stress and high in stability.

Description

technical field [0001] The invention relates to the technical field of vibration testing, in particular to a standard sample for vibration testing capability verification. Background technique [0002] Vibration testing proficiency verification is a verification of whether the National Accreditation Committee confirms the equipment and technical level of the vibration laboratory to ensure the scientificity, reliability and authenticity of the test results. For this verification, a standard sample must be provided to confirm the compliance of the test results of the assessed unit with the test results of the National Accreditation Committee. [0003] The existing standard samples directly use harmonic oscillators, the vibration characteristics of the vertical table and the horizontal slide table are difficult to be tested, and the dynamic stress is large and the stability is poor. Contents of the invention [0004] In order to solve the problems in the prior art, the prese...
