Blocked force methode
WebWe can directly measure the Blocked Forces by placing force transducers between the component and the test rig. Some of the challenges encountered with this method include measurement of rotational moments, challenges designing a rigid test bench at higher frequencies, and limitations on where the force transducers can be easily mounted (e.g ... WebIn contrast, this publication extends the NTPA methods by the component-based blocked-force method to achieve high accuracy and low computational effort. The parallel use of the classical direct- force method allows for a direct comparison of the sound contributions between the classical and component-based TPA families. 3. Solution approach In ...
