Impedance Head for Measuring Driving Force

Dytran model 5860B is an IEPE impedance head, consisting of a 100 mV/lbf force sensor and a 100 mV/g accelerometer within the same housing, designed to simultaneously measure driving force and resultant acceleration at the point of force applied to a test article.

Dytran‘s Model 5860B is an IEPE Impedance Head for measuring driving force. It also consists of a 100 mV/lbf force sensor and a 100 mV/g accelerometer within the same housing. Which is designed to simultaneously measure driving force and resultant acceleration at the point of force applied to a test article.

Firstly, one method to excite a larger test object, is to vibrate the structure using an electro dynamic shaker. Attached to the test object by a stinger and an impedance head.

Secondly, the driving point impedance is measured over frequencies of interest. Output signals from the impedance head may be then fed to a spectrum analyser and with appropriate software. Used to compute the dynamic impedance function.

Dynamic impedance is a designed Force/Velocity. Force is read from the 5860B. Therefore, a single integration of the accelerometer signals yields velocity. So computations are made by an appropriately programmed spectrum analyser. Then the dynamic impedance function is displayed graphically.

Ideal for applications such as modal and structural analysis.
