A rotational energy harvesting device that successfully reconciles high power density with mechanical durability through a hybrid sliding‐and‐bouncing kinematic mechanism is reported. The success reported in our paper includes addressing a dilemma where enhanced electrical output comes at the cost of increased friction and wear, limiting the practical ...

Optimization and Experimental Testing of the Drag Torque Model Based on the Cavitation Effect
In the non-braking operation of the wet brake in a heavy vehicle's hybrid power transmission system, the friction pair produces a drag torque due to the power loss caused by the viscous action of the oil.
