摘要：There exists a great difference between the existing structural model of
   Permalloy magnetoelastic force transducers and the actual situation.For
   precise and quantitative analysis and research on the magnetoelastic
   effect of Permalloy,a representative model that regarded the Permalloy
   sensor as a two dimensional Permalloy plane unit was proposed,which
   reduced the difficulty for solving the problem.The ratio of stress to
   area was used as the appraisal and estimation criterion of the different
   structural model of the sensor.Finite element analysis software SSAP93
   was utilized to calculate and analyze the different structures of the
   studied sensor comparatively.The ultimate results of the finite element
   analysis determine the structure and size of the Permalloy
   magnetoelastic force transducer.
