Analysis and Optimization of Structural Parameters Based on ANSYS in ECT

Electrical Capacitance Tomography(ECT) is a mechanism based on the process of capacitive sensor imaging technology,electrode capacitance sensor array of 12 ECT system background.We describe the calculation of sensitivity field,using ANSYS finite element analysis tool for large-scale establishment of capacitance sensor structural model,and get the distribution of sensitivity field between the electrodes,the capacitance sensor capacitance change in the situation of different parameters in order to avoid oscillation near the particle and particle in the global into local optimum,and the improved PSO search strategy and improvement of chaotic mix of new algorithm.Sensitive to the overall sensitivity to the size of system performance field goal to optimize the capacitive sensor structure,we find the optimal structural parameters of the sensor.For the electrical capacitance tomography image reconstruction we provide a new way of thinking.
