基于Pareto磁性液体微压差传感器优化设计
Optimal design of magnetic fluid micro-pressure difference sensor based on Pareto solution
摘要
Abstract
An adjustable range magnetic fluid micro-pressure difference sensor was designed and researched.The shell of the sensor was a glass pipe,in which a cylindrical permanent magnet was placed in the middle.The magnetic fluid was adsorbed on both ends of the permanent magnet.Two ring magnets were fixed on both ends of the pipe to provide restoring force to the middle permanent magnet.Hall element was used as transformation element and its measuring position could be changed by sliding the support,and the multi range measurement could be realized.The performance parameters of the sensor are derived,and the finite element simulation analysis is carried out.All parameters were optimized based on the Pareto optimization solution.The results show that the sensitivity and range of the sensor are increased,while the size is decreased after optimization.The relationship between the output voltage and the measured pressure of the sensor under three different ranges was analyzed by simulation and experiment and sensitivity of the sensor was carried out.Finally,the dynamic performance of the sensor is analyzed theoretically and simulated.The result shows that the dynamic performance of the sensor is improved after optimization,which verifies the feasibility of the design.关键词
