Preparation of strontium titano-oxalate electrorheological fluid and experimental study on the buffer

Abstract

Based on the shock absorber as the application background, a kind of Strontium Titano-Oxalate (STO) electrorheological material was synthesized. According to the mass ratio of STO electrorheological fluid to dimethyl silicone oil of 1:2. When the electric field intensity is 4 kV/mm and the shear rate is 3000 s-1, the maximum shear stress of the material is more than 9 MPa, and it has good temperature stability and anti-settlement performance. The STO electrorheological fluid was applied to the newly designed buffer, and the simulation test was carried out by using the fixed voltage, PID algorithm and fuzzy control algorithm respectively. The results show that the electrorheological buffer has the best anti-impact effect under the control of fuzzy algorithm, and the damping force and displacement peak value of the rear seat decrease by 30.5% and 19.1%, respectively. Good active control effect is obtained.
