| Abstract: | The capacitance weighing system is electromechanical dynamical systems,which includes automobile plate spring,measuring circuit and other major parts.In order to increase modeling accuracy,it is not only the need consider mechanical freedom,but also the need to consider the electrical freedom.Therefore,the dynamic model on the basis of Lagrange-Maxwell equation is presented.The simulation results and the test data show that the modeling method is feasible and effective. |
