  • Achieving quality in modal excitation - Brüel & Kjær
    a through hole design of the modal exciter and exciter fixture whereby the exciter can be slid along the wire A chuck assembly that clamps the exciter to the wire at the desired position replaces the traditional exciter table In connection with a lateral exciter stand the tension wire concept becomes especially simple and elegant The piano wire goes through the exciter then goes around a pulley and connects to a spring fastened to the base of the exciter stand A double threaded boss placed in between the spring and the base achieves adjustable pre tensioning This pre tensioning feature can also be achieved by using the DC Static Centering Unit Type 1056 optional with power amplifiers Types 2732 and 2720 but mandatory with Type 2721 This allows for use of piano wire stinger technology without a dedicated horizontal exciter fixture as described above especially useful when limited space or skewed angle mounting is necessary The DC Static Centering Unit Type 1056 has another significant advantage for modal testing namely that of providing the test specimen with a pre load capability Many structures require an accurately controlled static preload force in order to take up the slack in bearings gears or joints Failure to apply such a preload will often add significant problems to the modal parameter extraction algorithm Distributing and minimising dynamic force levels There are several reasons why exciting the structure under test with the smallest possible force level at more than one input location is desirable First force levels that are too high may drive the structure into non linear behaviour Second higher force levels require larger exciters which by necessity have more massive armatures leading to increased force drop offs at resonance frequencies Third large and complex structures that exhibit local modes generally require force inputs at several distributed locations in order to excite all modes sufficiently well In addition to the above two modes occurring at the same frequency a situation commonly known as repeated roots may occur in certain mostly bi symmetrical structures The only way to obtain a valid modal model in such a situation is by employing a modal test setup with multiple inputs i e a MISO or MIMO test strategy Choosing the best exciter location Theoretically exciting at any arbitrary location should excite all modes except those that have a node line at that exciter location In practice however it is necessary to have a good exciter location for a given mode This is much more demanding than simply requiring that bad locations i e node lines be voided It is therefore usually necessary to evaluate many exciter locations before picking the best and fewest numbers This process is often referred to as an exciter location survey One key is to try as a many exciter locations as possible Obviously using a lightweight modal exciter is a definite advantage because it is quick and easy to move and set up A rugged and dedicated lateral exciter stand allowing for easy
