Blocked force messung
WebForce and stiffness are important properties of piezo actuators. Find out more on this topic here. WebThe concept of the Blocked Force method introduces blocked forces which are independent of the receiver structure, thus allowing measurement of transfer functions without isolating the source. In this research, a stator / rotor assembly is considered as the source. This assembly is bolted to a test-housing, considered as the receiver.

Maximum, or blocked, force (F block) occurs when there is no displacement.Likewise, at maximum displacement, or free stroke, (ΔL fs) no force is generated.When an external load is applied (A), the stiffness of the load (k e) determines the displacement (ΔL A) and force (ΔF A) …
WebJun 5, 2024 · Blocked force TPA (also called in situ Source Path Contribution Analysis, in-situ TPA and component TPA) is a development of the classic TPA approach and has been attracting considerable recent attention. Blocked force TPA is based on very similar two stage measurements to classic TPA but has two major advantages: there is no need to …
WebSep 11, 2009 · The exact blocked force and moment were obtained by calculating the free velocity and mobility matrix of the free source beam and then applying Eq. (6). Results are shown in Fig. 3. When exact input data is used, the blocked force and moment are predicted exactly using Eq. (12) (curve not shown).
