Abstract
A single-range accelerometer can not meet with the requirements of some special working environments,in which require testing the acceleration parameters ranged from several g to thousands of g.On the other hand,many measurement errors and inconvenience will be produced due to the spatial and mounting limitation from the usage of several accelerometers.To solve the above-mentioned problems,a multi-ranged micro accelerometer containing four accelerometer units(10g,100g,500g,and 10000g) was introduced in the present works.The structural design and static/dynamic simulation of the multi-ranged micro accelerometer were also elaborated,and the static and dynamic characteristics of the encapsulated multi-ranged micro accelerometer were calibrated.The calibration results showed that the multi-ranged micro accelerometer displayed good static and dynamic characteristics, and can be used for the measurement of the high-low range acceleration.
