Project Description

Electrodynamic Shaker

Electromagnetic Shaker | Electrodynamic Vibration Test System China Manufacturer

Electrodynamic Vibration Shaker is intended to simulate the vibration conditions such as Sine, Random, Classic Shock, Resonance, etc., under laboratory environment to determine the impact strength and reliability of specimens in the application. Thus, it is an indispensable machine to implement the research & development of new products, maintain a stable quality level during production and evaluate the ability of final products and elements to withstand vibration in the process of transportation and use.

This electrodynamic vibration test system is specially designed to meet the needs of long-term work. It can achieve vertical and horizontal vibration after installing a vibration-resistant base. In addition, the standard platform is equipped with the best air pressure isolation device to minimize the vibration transmitted to the building. In most cases, no additional foundation is required.

Unlike the traditional mechanical vibration shaker, which uses an eccentric cam device and adjustable eccentric weight to fulfill vibration, the working principle of this electromagnetic shaker is similar to the loudspeaker. The electric conductor moves under the interaction of electromagnetic forces in the magnetic field. The force to accelerate the moving part is generated by the balance between driving current and magnetic flux.

The vibration table, power amplifier and vibration measurement and control system constitute a complete vibration test system. It is in accordance with relevant national and international standards such as MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIS, BS, etc.

INQUIRE

The electrodynamic exciter is extensively used in the fields of power, aerospace, aviation, rocket, nuclear industry, communication, electronics, automobile, etc.

Contents in IEC 62133 and UN38.3 specify simulations of the vibration tests of lithium-ion batteries during transportation. The tests were divided into large batteries (greater than 12kg) and small batteries (less than 12kg cells or small batteries). The vibration frequency was 7~200Hz, and the X, Y and Z axes were sinusoidal sweep frequency according to a specific acceleration.

In order to suit the different operating requirements of various end-users in the market, there are lots of sub-models and configurations to choose from for purchasers. They are different in frequency, max exciting force, max displacement, max velocity, max load, armature weight, armature diameter, etc.  Besides, the Shock Tester is also available here. Welcome to consult Amade.
