The ankle mechanical impedance is a dynamic operator that maps the time-history of angular displacements onto the corresponding time-history of ankle moments.
Ankle mechanical impedance may provide an opportunity to better characterize ankle dynamics.
This portable multimode adhesive bond testing instrument uses pitch-catch modes, mechanical impedance analysis (MIA), and resonance technologies to inspect materials that are commonly used in aerospace, energy, and automotive industries.
Its basic model includes all pitch-catch modes while the BondMaster 600M multimode model features all three bond testing inspection modes including resonance and mechanical impedance analysis.
Basically, the vibration is the result of the relationship between acting force during machine operation and mechanical impedance
considered relatively steady, force variation being responsible for vibration fluctuation, therefore for machine's operating condition changes.
The method is based on measuring the mechanical impedance
of a sample.
Because a DMA's three and velocity can be varied independently across a wide range (by altering the length, width and thickness of the piezo crystal beam, and by adding any necessary beams), the exciter's mechanical impedance
can be adjusted in a manner unachievable with conventional moving coil or piezoelectric exciters.
Thus, E' is assumed to be directly related to the storage portion, S, of the mechanical impedance
of the tip-sample contact in the dynamic model (see Fig.

A relatively young ISO 9001 certified company, Sonotron NDT designs, manufactures, and markets non-destructive test (NDT) equipment and technologies for ultrasonic inspection, mechanical impedance
analysis (MIA) and eddy current implementations.
All these aspects of ankle function may be characterized by its active and passive mechanical impedance
A vertical smooth blade with an array of strain gauges was designed to dynamically measure mechanical impedance
of soil at multiple depths.
