In addition, three electrodynamic shaker tables can test loads up to 7,000 lbf.
The amplifier that drives an electrodynamic shaker needs to supply enough current at a sufficient voltage to run the desired test.
Madrid, Spain, August 20, 2015 --(PR.com)-- Aerospace expert, Mecanizados Escribano has expanded its vibration test capabilities with a new electrodynamic shaker system from Bruel & Kjaer.
In this paper we make efforts on the experimental analysis of the vibratory alignment and the insertion of peg-in-hole, when the peg is compliantly supported and the bushing is immovably attached on the platform of an electrodynamic shaker. The passive compliance device with the remote compliance centre for the peg is used.
The boards were mounted with standoffs at the four corners to an electrodynamic shaker. Failure data were divided into four groups depending on component location on the board because they experienced different stress levels.
To answer this, an experiment was carried out on a Derritron electrodynamic shaker controlled by a PC with Lab VIEW software and a National Instruments data acquisition board.
In order to set the electrodynamic shaker in motion we use a National Instruments signal generating and measurement card.
The Eplexor 500N DMA operates from -160[degrees]C to 500[degrees]C and features two independent drives for the static load by a servomotor for up to 1,500 N and for the dynamic force of up to [+ or -]500 N by the electrodynamic shaker. For rubber quality control and research, the Eplexor 500N is said to be useful for dynamic component testing, durability tests, analysis of viscoelastic material properties, and more.
Tests will be carried out at the Intespace facility in Elancourt, northern France, which is equipped with a l60kN electrodynamic shaker configured to provide the best compromise between power and embeddable mass for the testing of such equipment.
An electrodynamic shaker positioned at midlength harmonically excited the test structure.
