Electrodynamic Shakers | Electrodynamic Shaker Systems

Electrodynamic shakers makes use of an electro-mechanical assembly to product vibration through electromagnetic force. These electrodynamic shaker systems can precisely generate either single, or multi-axis vibration using sine, random, sine-on-random, or random-on-random accounts. Usually these ED shakers are utilized to figure out the products ability to either run within it’s intended environment, or to target resonance in the product to determine weakness. Any type of product moved by road, sea or air, is subjected to vibration tests throughout its manufacturing procedure.

These tests supply essential details relating to the behavior of the manufactured part before advertising and marketing, in order to prevent them breaking in the future. All the vibration tests, both vertical and also horizontal, may furthermore go through temperature as well as relative humidity tests, integrating the vibration test with making use of a climatic chamber. The electro dynamic shakers from Wewon attach to any kind of electrodynamic vibration system. We work with any kind of brand, offering, with a total assurance, the perfect setting for your interface.

An electrodynamic vibration shaker system is a type of mechanical testing equipment used for simulating and measuring the effects of vibration and shock on structures, components, and products. These systems typically consist of a shaker table, an amplifier, a controller, and a series of sensors and data acquisition devices.

The shaker table is the heart of the system and is responsible for generating the vibration. It typically consists of an electromagnetic coil, a moving assembly, and a mounting platform. When an electrical signal is sent to the coil, it creates a magnetic field that interacts with the moving assembly, causing it to vibrate at a specific frequency and amplitude. The mounting platform is typically designed to accommodate the test specimen and must be able to withstand the vibration without introducing any unwanted resonances or damping effects.

The amplifier is responsible for providing the power necessary to drive the shaker system. It typically consists of a power supply, an oscillator, and a feedback circuit. The power supply provides the voltage and current needed to drive the electromagnetic coil, while the oscillator generates the electrical signal that determines the frequency and amplitude of the vibration. The feedback circuit is used to ensure that the system maintains a constant vibration level despite changes in the test specimen or external conditions.

Electrodynamic vibration shaker system provides a complete series of shock as well as vibration testing that includes force dimension, generation, as well as control. Lots of advanced features are included in both the hardware and also software to offer state-of-the-art solutions for shock as well as vibration testing.
Electrodynamic vibration shaker (both air- and water-cooled) are available as turnkey vibration test systems that include: shaker tables, power amplifiers, slip tables, shaker head expanders, fixtures, as well as thermal barriers for environmental testing.
The primary step in selecting an appropriate shaker is to define the test accounts that are to be run (sine, random, shock, replication, and so on) and also to gather dimensional details on the test short article as well as fixtures that will certainly require to be utilized. The dimensions will be custom-made according to customer’s testing requirement.
For any electrodynamic shaker, the added mass of the DUT as well as fixtures moves the efficiency envelope from the black line to anywhere the blue line could be. Shaker sizing computations are done to ensure all test profiles will certainly fit within the envelope.
Electrodynamic type vibration testers (ED Shaker) are readily available in horizontal and vertical operation types suitable for vibration settings. Our electrodynamic vibration shaker can simulate such vibration by setting wave of vibrate, vibration period as well as other specifications according to their testing requirement.
Our electrodynamic vibration shaker performs vibration test on spare parts and finished products. Vibration result the revolving pulse, vibration and also force produced from mechanical operation or quake. Usually vibration phenomenon happens in the procedure of ship, airplane, road spacecraft, vehicle as well as propeller.

The controller serves as the brain of the system and is responsible for setting up and running the tests. It typically consists of a computer or a programmable logic controller (PLC) and a software package designed for vibration testing. The software package allows the user to set up the test parameters, monitor the system performance, and collect data from the sensors and data acquisition devices.

Sensors and data acquisition devices are used to monitor the performance of the shaker system and the test specimen. They typically include accelerometers, displacement transducers, and strain gauges. Accelerometers are used to measure the acceleration of the test specimen, while displacement transducers are used to measure the displacement of the shaker table. Strain gauges are used to measure the strain in the test specimen and are typically mounted at critical locations to detect any changes in the mechanical properties of the specimen.

What Is The electrodynamic shaker ? Electrodynamic (ED) shakers are well suited for the majority of vibration tests and supply several advantages over different approaches. ED shaker from Wewon have very linear practices, so controlling the vibration test might be less complicated or possible when not or else possible.

Vibration result the revolving pulse, vibration and also force generated from mechanical procedure or quake. EV series of electromagnetic shaker system simulate the vibration environment under the laboratory condition, and also test the impact strength as well as reliability of various vibration test applications. Vertical and horizontal vibrations can be accomplished by the setup of vibration resistant base.

https://www.wewontech.com/electrodynamic-shaker/ How does the electrodynamic shakers work ? Vibration testing is done to introduce a forcing feature right into a structure, usually with the use of an electrodynamic shaker or electrodynamic shaker systems. These generated vibrations, vibration tests, or shaker tests are made use of in the laboratory or manufacturing flooring for a selection of points, including certifying products throughout style, conference standards, governing credentials (e.g. MIL-STD 810, etc.), fatigue testing, screening products, as well as reviewing performance.

Electrodynamic (ED) shakers are well matched for a lot of vibration tests and also offer several benefits over alternative strategies. Contrasted to hydraulic shakers, ED shakers are capable of much higher regularities. These high frequencies can be extremely important in testing electronics and electronic assemblies. ED shakers are likewise with the ability of replicating a wide range of shock. Last but not least, ED shaker have really linear behaviour, so regulating the vibration test may be easier or possible when not or else possible.
