Many geometric problems of interest to mathematical visualization applications involve changing structures requiring mathematical simulations, such as the moves that transform one knot into an equivalent knot. In this paper, we propose to explore a unique paradigm that makes use of self-deformable object models embedded in mathematical space, supplemented by energy-driven relaxation and user-defined...
This paper presents system modeling and coupling analysis of a proportional solenoid valve (PSV) with pulsewidth modulation (PWM) control mode. The coupling analysis is adopted to reveal the internal relations among the electromagnetic, mechanical, fluid, and electrical subsystems based on the integrate proportional pressure valve mode for the PSV system. Then, a simplified and practical PWM strategy...
A dynamic lubrication model is built based on the lubrication theory of the oil film for optimization design of the inner radius of the sealing surface of slipper, considering the macro and micro motion of the slipper. Reasonable design criterion is presented, adopting the oil film characteristics, dynamic stiffness and minimum power loss as the optimum conditions. Furthermore, the experiments of...
