  • How High in Frequency Are Accelerometer Measurements Meaningful
    of the. accelerometers when they are subjected to pyroshock [1]. In order. to support the development of a series of more robust MEMS. accelerometers, this paper answers the question: How high in. frequency response are accelerometer measurements meaningful?
  • A Simple Frequency Response Function
    This article will attempt to explain the basic theory of the frequency response function. This basic theory will then be used to calculate the frequency response function between two points on a structure using an accelerometer to measure the response and a force gauge hammer to measure
  • Selecting Accelerometers for and Assessing Data from Mechanical Shock Measurements
    After first clarifying what mechanical shock is and why we measure it,. basic requirements are provided for all measurement systems that. process transient signals. High- and low-frequency dynamic models for. the measuring accelerometer are presented and justified. These models. are then used
  • Development of a Damped Piezoresistive MEMS High Shock Sensor
    in this paper. In this approach, the resonance frequency is intentionally lowered to reduce the response of the accelerometer to higher frequency energy that may be present in shock events. The relatively low resonance enables displacements of the seismic element sufficient to introduce squeeze film
  • Field Evaluations of a Damped MEMS Shock Sensor
    amplification during violent events by orders of magnitude over conventional undamped PR MEMS designs. Such damping enhances survivability and reduces the need for filtration, whether mechanical or electrical, to block unwanted high-frequency output. Analysis of results shows that the frequency response
