This element is usually designed in form of a cantilever beam loaded with a mass. Acceleration causes bending of the beam, which produces a change of electrical resistance proportional to the applied acceleration. Main advantages of piezoresistive accelerometers in comparison to other types, e.g., piezoelectric and capacitive, is their robust and highly dynamic behavior, which qualifies them for application in high impact shock applications. Mechanical damping is typically implemented with silicon oil in a way that the output signal is undistorted over a wide frequency range. These characteristics principally qualify them for the application in drop tests carried out at BAM, for which they are calibrated over the frequency range from 1 to 4 kHz. However, using silicon oil for damping, has the drawback of temperature dependent change of its viscosity, leading to temperature dependent deviation of the accelerometer’s sensitivity. This study presents experimental results of the temperature behavior of a piezoresistive accelerometer with a dynamic range up to ±5000 g. This type of accelerometer is applied for drop tests which are partially performed at temperatures of -40 or +100 °C. 34rd Danubia - Adria Symposium on Advances in Experimental Mechanics - Book of proceedings 978-88-8303-863-1 https://www.openstarts.units.it/handle/10077/14921 34th Danubia-Adria Symposium on Advances in Experimental Mechanics Trieste, Italy 19.09.2017 22.09.2017 Matthias Bartholmai Klaus-Dieter Werner Sergej Johann Werner Daum eng uncontrolled Accelerometer eng uncontrolled Temperature behavior eng uncontrolled Drop test Analytische Chemie Datei im Netzwerk der BAM verfügbar ("Closed Access") Graue Literatur
