Analysis and Simulation the Modal Testing Suspension Long-travel Field Electromagnetic Force Device

Electromagnetic force device is one of the key components of the modal testing suspension system,the design of this structure not only has a direct influence on the following difficulty of control system design,but also affect the performance of the system.Therefore on the basis of the electromagnetic force device analysis,to simulate the magnetic field analysis with ANSYS,get the magnetic line of electromagnetic force device,the distribution of magnetic induction,and educe the characteristic of electromagnetic force device's magnetic field distribution.Its result provided a theoretical basis for optimization the structure of the electromagnetic force device.
