Vibration table is suitable for research, development, manufacturing, testing of electronic devices, electromechanical products, auto parts, instruments, toys, and other industries in the transportation and use of products in the process of collision and vibration. Vibration resistance test. After you understand the vibration test specifications, you should choose the appropriate vibration testing equipment according to the specifications and the weight and shape of the test sample. At present, the most commonly used vibration detection equipment on the market are electric vibration table, mechanical vibration table and hydraulic vibration table. Here is a brief overview of how to choose.
Several principles should be paid attention to when selecting a vibrating table
Determine the rated excitation force according to the product of the mass of the tested product (including the fixture) and the maximum acceleration value of sinusoidal vibration (or the root mean square value of random vibration), plus a 30% margin;
Select the upper and lower working frequencies of the vibration table according to the frequency range of the test specification;
According to the vibration control requirements of the test specification-sinusoidal vibration, random vibration, etc., select the controller that the shaker should be configured;
When the test requires horizontal vibration, a horizontal slide should be configured;
Other specifications of the test, such as maximum displacement, maximum speed, maximum carrying capacity, and whether the vertical expansion table (working frequency of the expansion table) should be configured according to the size of the test piece.
