For testing rolling angular rate and axial acceleration of rocket projectile, sensors with high anti-impact capability are needed. MEMS-based inertial sensor is adaptive to the high shock circumstance. This work introduces a measuring system based on MEMS gyros and MEMS accelerometer. By set MEMS inertial sensor in air delivery land mine of rocket, use polyurethane plotting the sensor and circuit...
A new type digital inclination angle measuring instrument is researched, which includes a low power, low noise, low cost MEMS accelerometer and a fully integrated mixed signal System-On-a-Chip MCU C8051F040. The signal processing of MEMS accelerometer is divided into conditioning, sampling, converting, and temperature compensation, then calculating the inclination angle value, and displaying the angle...
The research on on-line measurement and prediction technology for vehicle motion state is developed in view of shortage that the existing active safety warning systems, which focus on monitoring and warning, lack prediction process for vehicle motion state. MIMU (Micro Inertial Measurement Unit) is designed independently in order to measure vehicle motion state parameters. Then vehicle attitude and...
A new structure of tunneling gyroscope which is high-accuracy and low-range was presented in this paper, as well as the structure and the operating principles of this gyroscope were analyzed. Besides, the simulations were made in this paper which is close to the principle. Then the structure was fabricated by MEMS technological processes. And its tunneling effect was tested by HP4156C high precise...
