The thermal deformation of elastic ring of YDC—Ⅲ89 turning dynamometer is analyzed by using ANSYS.It is shown that the width of elastic slot is little changed while the dimensions of elastic ring changes and is reduced while linked by screw.The effect of thermal deformation on preload which loaded on sensor through is simulation experiment.Based on analysis and experiment
a new method which improves the performance of the dynamometer is proposed.The dynamometer is fully reached the dynamometer standard stipulated by CIRP-STCC.The cutting results show that the errors caused by new dynamometer decrease.
