The errors in structure of the spoke type transducer include the error of linearity due to the difference between the positive strain and the negative strain
and the error of hysteresis and repeatability because of the variety of the friction on the supporting surface.The error sources are analyzed.Altering stiffness proportion of the upside and underside of the flange to make the positive strain equal to the negative strain
and increasing stiffness of the flange and decreasing the supporting face to reduce the variety of the friction
