Measurement and Analysis of Low Frequency Vibration
Low frequency vibration occurs especially in ground transportation, either as a cause in adjacent environment or within the vehicle itself. The piezoelectric accelerometers commonly used for vibration measurement are not suitable, hence other sensors capable of measuring accelerations down to sub-hertz region have to be used. Based on some previous experience with MEMS acceleration sensors a th...
متن کاملFast Thermal Calibration of Low-Grade Inertial Sensors and Inertial Measurement Units
The errors of low-cost inertial sensors, especially Micro-Electro Mechanical Systems (MEMS) ones, are highly dependent on environmental conditions such as the temperature. Thus, there is a need for the development of accurate and reliable thermal compensation models to reduce the impact of such thermal drift of the sensors. Since the conventional thermal calibration methods are typically time-c...
متن کاملMiniaturization of Inertial Magnetoelectric Vibration Velocity Sensor with High Frequency Response at Low Frequency Band
The frequency response of the inertial magnetoelectric vibration velocity sensor is limited in the low frequency range due to the character of second order high pass filter of the structure. For better performance in the low frequency range, the traditional method is to increase the initial mass of the sensor which will increase the size and weight tremendously. This paper presents a frequency-...
متن کاملReview Paper: Inertial Measurement
Applications of inertial measurement units are extremely diverse, and are expected to see a further increase in number due to current trends in robotics as well as recent advances in Micro Electromechanical sensors (MEMS). The traditional method of inertial measurement has depended on costly, power-intensive, error-prone Inertial Measurement Units (IMUs) that represent a single point of failure...
متن کاملLow-frequency seismic deghosting
We evaluated a solution to seismic deghosting that deghosts the low-frequency components of the seismic pressure data. In an approximation that neglected the dependence on wavenumbers, the low-frequency deghosted pressure field was computed trace-by-trace as the sum of the pressure field and its scaled temporally integrated and temporally differentiated fields. We gave simple numerical examples...
