The Applications and Selection of a Vibration Shaker Table

The vibration shaker is also called a vibration exciter or a vibration generator. It's a equipment that uses electrical, electrohydraulic, piezoelectric or other principles to obtain mechanical vibration. Its principle is to input an trigger signal to a coil placed in a magnetic field to drive a workbench connected to the coil. Electric vibration shaker are mainly used for vibration measurement above 10Hz and the maximum pressure can be triggered to 200N. The hydraulic vibration shaker is commonly used in the frequency range below 20Hz, and the properties of the vibration signal are controlled by an electro-servo system. The hydraulic drive system can provide larger displacement and shock force. Vibration shaker tables can be used for the calibration of accelerometers, and also for the vibration performance tests of electro-acoustic equipment and other vibration tests. For different test specimens and technical specifications, different vibration shaker should be selected with different structures and trigger ranges.

Application of vibration shaker products

Vibration shaker are suitable for sample-related vibration tests in industry laboratories and production lines of automotive parts, electronics components, components, medicine, food, furniture, gifts, ceramics, packaging, etc. Such as environmental acceptance tests, quality identification tests, reliability identification tests, durability tests, vibration simulation analysis, material characteristic tests, fatigue tests, and vibration prevention improvements, etc. The vibration environment of the product during manufacturing, assembly, transportation and use is simulated to evaluate the vibration resistance, reliability and integrity of the structure.

The transport simulation vibration testing machine is used to simulate the environment of electrical, electronic, auto parts and other products and goods involved in transportation during transportation, and to test the vibration resistance of their products. All the functions needed for vibration test are: sine wave, frequency modulation, sweep frequency, programmable, frequency multiplication, logarithm, maximum acceleration, amplitude modulation, time control, and can be upgraded to achieve full-functional computer control, simple acceleration constant/constant amplitude. The equipment has been tested continuously without failure for 3 months, the performance is stable, and the quality is guaranteed.

The purpose of vibration testing is to determine that the designed and manufactured machines and components can withstand the vibration generated by the vibration shaker machine or itself during transportation and use without being damaged and exert their performance to achieve predetermined life reliability. With the improvement of reliability requirements for products, especially aerospace products, the development of vibration test systems as the key equipment for reliability testing is becoming more and more important.
