The Finite Element Method on the On-line Monitoring Elastic Element for measuring Forces of the Rotating Machine

This paper simply introduces the device of on-line monitoring for the thrust of the rotating maching,then discussed the finite dement analyses on the on-line monitoring elastic dement for measuring thrust in detail,in order to develop the performance of the sensor and the device,we calculated the distribution of the stress、strain、axial displacement in the elastic element using the finite element method when the axial forces F=3×104N,the result is very satisfied.
