To provide sufficient damping torque performance for heavy tracked vehicle's suspensions, the design of a novel high-torque rotary magnetorheological (MR) damper with a parallel plate channel, referred to as PPCRMRD, is presented and the prototype of the PPCRMRD is manufactured. The theoretical model of the PPCRMRD considering the Hybrid magnetic fields effect and leakage effects is proposed. The max damping torque and controllable damping torque of the PPCRMRD are tested on the established experimental setup based on MTS rotary test system and compared with the theoretical results based on the proposed theoretical model, the theoretical model ignoring leakage effect and Bingham plastic model respectively. Under the sinusoidal excitation of 0.05 Hz and amplitude of 35°, compared with the theroetical model without considering the leakage gap and the Bingham plastic model, the maximum error of the proposed model is reduced by 11.08% and 40.66%. The tested max damping torque and controllable damping torque of the PPCRMRD under sinusoidal excitation with an amplitude of 35°and frequencies of 0.1 Hz are as high as 2677 and 1711 N m. The research results show that the principle of the PPCRMRD can provide sufficient damping torque as well as a wide range of controllable damping torque and the proposed theoretical model of the PPCRMRD can describe and predict its damping torque performance precisely.

“…Meanwhile, the inadequate contact force between the wheel and track tread may also cause the turning controllability of the vehicle decrease. In terms of the semiactive control algorithm of the tracked vehicle, most studies care only about the improvement of the ride comfort [19][20][21]. The problems such as the reasonable control between the ride comfort and safety and optimum scheduling of the damping control gain under different disturbances are waiting to be solved.…”

The riding conditions for a high-speed tracked vehicle are quite complex. To enhance the adaptability of suspension systems to different riding conditions, a semiactive and self-adaptive hybrid control strategy based on disturbance velocity and frequency identification was proposed. A mathematical model of the semiactive, self-adaptive hybrid suspension control system, along with a performance evaluation function, was established. Based on a two-degree-of-freedom (DOF) suspension system, the kinematic relations and frequency zero-crossing detection method were defined, and expressions for the disturbance velocity and disturbance frequency of the road were obtained. Optimal scheduling of the semiactive hybrid damping control gain ( sky , ground , hybrid ) and selfadaptive control gain ( V ) under different disturbances were realized by exploiting the particle swarm multiobjective optimization algorithm. An experimental study using a carefully designed test rig was performed under a number of typical riding conditions of tracked vehicles, and the results showed that the proposed control strategy is capable of accurately recognizing different disturbances, shifting between control modes (semiactive/self-adaptive), and scheduling the damping control gain according to the disturbance identification outcomes; hence, the proposed strategy could achieve a good trade-off between ride comfort and ride safety and efficiently increase the overall performance of the suspension under various riding conditions.
