1Array Shape Estimation Using Partitioned Eigenstructure Method with Sources in Unknown Localizations显示文摘Advanced array processing approaches require accurate knowledge of the location of individual element in a sensor array.Most array shape estimation methods require the directions of sources.In this paper,an array shape estimation method based on eigen-decomposition is presented.The directions of sources do not need to be considered in advance and optimal array shape is generated through a series of iterations.To further improve the accuracy of this algorithm,a partitioned eigenstructure method is introduced.Numerical simulations using non-partitioned and partitioned method are conducted to verify the performance of the proposed technique.Changgeng Shuai Shike Zhang Jiaxuan Yang Sitong Zhou 2018Sound & Vibration2018,52,4:0
2Design and Optimization of the Electromagnetic Actuator in Active-Passive Hybrid Vibration Isolator显示文摘The design and optimization of actuators are difficult andcritical for the active-passive hybrid vibration control system. Inthis paper, an electromagnetic actuator model is establishedbased on Ohm’s Law for magnetic circuit considering theleakage flux. The 600N electromagnetic actuators are designedand optimized based on ANSYS simulation according to theengineering request. Its transient characteristics are studied. Theeffects of different structural parameters on its output force areanalyzed. The experimental results show that the structureparameters and output force characteristics of the designedelectromagnetic actuators satisfy the practical requirement.Jianguo Ma Changgeng Shuai Yan Li 2018Sound & Vibration2018,52,6:0
