一种抗冲击加速度传感器的设计

Design of an anti-shock accelerometer

随着应用领域的不断拓展,对加速度传感器的要求也越来越高。在某些应用场合,要求加速度传感器能够承受800g的冲击,普通加速度传感器在此冲击之下将发生断裂失效。介绍了一种金属悬丝摆式加速度传感器的工作原理,对加速度传感器悬丝支承进行了设计,根据悬丝支承的受力分析,通过增加限位结构,在未改变加速度传感器外形尺寸的情况下,将加速度传感器的抗冲击能力提高到1000g以上。

With the expanding of applications, the requirements for accelerometer performances are higher and higher. There are 800g-shock phenomena in some application environments, and ordinary accelerometers would occur fracture failures. The working principle of a metal wire pendulous accelerometer is introduced in this paper. The wire support structure of sensor is designed specially. In accordance with the stress analysis of the wire support, the anti-shock ability of the accelerometer can be up to lO00g or more by adding the displacement limit without changing the dimensions of the accelerometer.
