Abstract
Based on the theoretical and experimental analysis of the damping force characteristics of a magnetorheological shock absorber (MRSA) , the dynamic equation of a single degree of freedom shock mitigation system considering quadratic damping was established, and the generalized Bingham number (GBN) was defined. An optimal generalized Bingham number control strategy of magnetorheological shock mitigation system considering quadratic damping was proposed to achieve a soft landing. The acceleration, velocity, and displacement formulas of the payload were deduced, and the dynamic response of the magnetorheological shock mitigation system under different generalized Bingham numbers was analyzed. Simulation analysis and experimental tests verify that the optimal generalized Bingham number control strategy based on quadratic damping is superior to the optimal Bingham number control strategy based on linear damping in terms of soft landing control accuracy.
