[Abstract]:In order to meet the need of monitoring the health state of the semi-active suspension magnetorheological shock absorber and improve the reliability of the sensing system, an external integrated piezoresistive acceleration sensor of the magnetorheological damper was designed to measure the dynamic acceleration. According to the working characteristics of shock absorber and the characteristics of piezoresistive acceleration sensor, the concept of integrated acceleration sensor of shock absorber is put forward, and the integrated mode is determined. The design principle of integrated piezoresistive sensor is analyzed and the chip structure is selected. In order to ensure that the sensor has higher sensitivity and better dynamic characteristics, the main dimension parameters of the chip are determined by the combination of theoretical model derivation and finite element simulation, taking the measurement range as the constraint condition. Furthermore, the layout design of the chip is completed by theoretical analysis. According to the parameters of the designed acceleration sensor, the single degree of freedom suspension of the magneto-rheological absorber with integrated acceleration sensor is tested and analyzed under sinusoidal and random excitation. The results show that the designed accelerometer has good accuracy and dynamic stability and can meet the requirements of application.
