Quartz Flexible Accelerometer Partial Value And Scale Factor Stability Study

Quartz flexible accelerometer as the main use of accelerometer type, is used tomeasure the acceleration, the carrier is a kind of very important inertial components, invarious vector navigation and positioning, through measuring acceleration, speed orposition can get the movement of objects track, but because of the movement of able tomeasure the object interior only its acceleration, thus the accelerometer to inertialnavigation technology also has a very important meaning.Through the theoretical research and product test data show that the influence onaccelerometer as the main sensor pieces of system (or device) the main factor is thelong-term stability of the long-term stability of the accelerometer. If accelerometerlong-term stability performance is good, it is long, system calibration cycle of (or device)calibration cycle can relatively long. In the process of application of accelerometers,influence factors accelerometer long-term stability is partial value and scale factor thelong-term stability of the index, this paper discusses the accelerometer partial value andimprove the stability of scale-free factor long-term research plan, the main contents andimprovement measures are as follows:1.Firstly expounds the purpose and significance of the research project of subject,relevant background were introduced.2.Expounds quartz flexible accelerometer is given the working principle,accelerometer input and output model and partial value and scale factor model.3.Discusses the influencing the stability of accelerometer partial value reason, thepaper puts forward the countermeasures.4.Discusses the accelerometer scale factor influence the stability of the reasons andputs forward the improvement measures.5.Proposed the improvement measures of accelerometer stability.6.Summary subject for the subsequent achievement, and further improve theaccelerometer stability puts forward the work proposal.
