According to the work characteristics of the electromechanical actuator, a control scheme of direct DC electromechanical actuator based on discrete-time variable structure controller is designed. The effect of hinge moment is considered in the mathematical model, and the coefficients of its transfer function are appropriately amended. The effect of the three parameters in the design of discrete-time...
Based on the mathematical model of wet clutch engagement, a dynamic model of a tracked vehicle was developed by means of the software Matlab/Simulink. This model can be used to simulate the shift schedule, piston pressure and relative velocity. A two dimensional heat conduction model was also developed with reasonable selection of proper boundary conditions, contact pressure model and heat flux distribution...
After the improvement of the actual theory of cold roll forming and the practical rolling process, author present the concept of dynamic chain model and node model, research steel strip forming mechanism based on information system. The problems such as the forming process research, the effects of friction on the forming, analysis of stress and strain were studied in the new model. What is more important...
