Abstract

The invention discloses an extra-heavy sample vibration test tool and a use method. The extra-heavy sample vibration test tool comprises a bottom plate and a test plate arranged on the bottom plate. The left side of the top of the bottom plate is fixedly connected with a positioning plate, and the top of the positioning plate is rotatably connected with the left side of the test plate through a rotating block. The invention relates to the technical field of vibration tests. According to the vibration test tool for the extra-heavy sample and the use method, a first connecting block and a second connecting block are arranged, the distance between the first connecting block and the second connecting block is directly adjusted under the cooperation of a gear and a tooth plate, so that after an elliptical mechanism is abraded, the abraded part can be directly adjusted by adjusting the distance, the abraded part does not need to be replaced frequently, efficient conduction of the test can be guaranteed, the amplitude can be directly adjusted by adjusting the distance, more test data are provided for the vibration test while using is convenient, and the result of the vibration test of an extra-heavy sample is more accurate.

Description

technical field [0001] The invention relates to the technical field of vibration testing, in particular to a tool for vibration testing of super-heavy samples and a use method thereof. Background technique [0002] Vibration test refers to the test conducted on the object or model subjected to vibration to evaluate the anti-vibration ability of the product in the expected use environment. According to the type of vibration load applied, the vibration test is divided into sinusoidal vibration test and random vibration test. The sinusoidal vibration test includes rated vibration test and scanning sinusoidal vibration test. The scanning vibration test requires the vibration frequency to change according to a certain law, such as linear change or exponential change. The vibration test equipment is divided into two parts: loading equipment and control equipment. The loading equipment includes mechanical vibration table, electromagnetic vibration table and electro-hydraulic vibr...
