Design of Multi-threshold Acceleration Switch Based on Matlab
Acceleration switch can trigger switches according to the variation of external acceleration without complex control system and circuit.With the excellent characteristics of integration of sensor and actuator,zero power consumption and high reliability,multi-threshold acceleration switch has great application value in the fields of vehicle safety,aerospace and industrial equipment.In order to reduce the complexity of the measurement system and improve the reliability,we realized the design of a multithreshold and anti-overloading acceleration switch which can distinguish specific pulse width.Additionally,the magnetic elastic contact is designed to prevent the rebound phenomenon when switch is overloaded.Considering the coupling force of spring,magnetic elastic contact and magnetic,we built the dynamic model and analysed the influence of the acceleration threshold and the pulse width on the switch actuation.The numerical simulation shows that the proposed switch has accurate sensitivity of acceleration excitation with specific threshold and certain pulse width,and it also has the ability of anti-overload.Consequently,the proposed method provides a new method for designing acceleration switch.
