Vibration exciters used in vibration laboratories are vibration generators. When selecting vibration generators, suitable types should be selected according to the test frequency range. Electro-hydraulic vibration test system are suitable for the medium and low frequency range, electric tables are suitable for medium and high frequency range, and the vibration frequency of mechanical tables is lim...
Introduction As part of the effort to locate dependable sources of energy for the long term, novel approaches to energy production have been researched. Electrodynamic vibration generator systems have emerged as a viable solution that can collect vibrational energy and change the generation of electricity. This article explores the rationale behind these systems, how they function, and the myriad ...
Introduction There is a considerable amount of unrealized potential in the form of vibrational energy that is produced by things like factories and automobiles and by humans. Methods that make use of electrodynamic vibration generator systems show a great lot of promise as a way of tapping into this huge, but for the most part untapped, source of energy. These generators work by generating vibrat...
LVD-100KG/LVD-100KG-6D Electrodynamic Vibration Generator Test Table is according to IEC 60068, IEC68-2-6, JJG189-97, GB/T13309-91, GB2423 and other relevant standards. • LVD-100KG: Combined the Vertical and Longitudinal total 4 directions in one test table. • LVD-100KG-6D: Combined the Vertical, Level and Longitudinal total 6 directions in one test table. Q1: How to prevent the vibrat...
The terms “shaker table” and “vibration table” can refer to a variety of things in the field of vibration testing. Shaker tables are used for a variety of testing. These include vibration testing of structures, dynamic transducer calibration and general vibration testing of components. Shaker tables can be categorized under any of the following product categories. These inc...
IEC (International Electrotechnical Commission) is the earliest international standardization organization in the world. It was established in 1906 to enhance international mutual understanding and hope that national committees can use these international standards if their own conditions permit IEC is mainly responsible for international standardization of electrical engineering, electronic engin...
Vibration test is to simulate the various vibration environment impacts encountered by the product in the transportation, installation. This test is to simulate the various impacts encountered by the product in the transportation, installation and use environment. This kind of vibration environmental impact is used to determine whether the product can withstand various environmental vibrations. Vi...
IEC 60068-2-6 <Environmental testing –Part 2-6: Tests – Test Fc: Vibration (sinusoidal)> consists basically of subjecting a specimen to sinusoidal vibration over a given frequency range or at discrete frequencies, for a given period of time. A vibration response investigation may be specified which aims at determining critical frequencies of the specimen.The following is the original con...
During World War II and after the war, Western countries, especially the United States, have established a series of environmental testing ground, laboratory and developed environmental testing standards. Required by the US military, all weapons equipment, parts, materials, and ammunition must be sent to the environment laboratory to simulate environmental testing, and then sent to environmental t...
LED street lights become more and more popular in recent years, but a few days ago, the American Medical Association (AMA) just issued an official statement, warning that if the LED lights are too white and bright, it will release a large amount of blue light and expose to people directly, which would not only increase the probability of an accident because of the glare while driving, but also aff...
With the fast development of electrical industry in China, manufacturing enterprises scale grows constantly, international electric safety standards apply more and more widely. Lighting industry standards are also widely used. International standard IEC60598 general requirements and test cover classification of luminaries according to degree of protection against ingress of dust, solid objects and...
