The hysteresis curve is used to reflect the hysteresis phenomenon of the reducer,but in engineering practice,the morphologic characteristics of the hysteresis curve are ignored and default to have the loading rate independence.The loading rate dependence of the morphologic of the hysteresis curve of the reducer is demonstrated,and the specific impact is analyzed.Four parameters are proposed to characterize the morphological characteristics of the hysteresis curve,and the physical meaning of each parameter is given.Through further experimental research,it has been verified that the morphologic of the hysteretic curve of the reducer has the loading rate dependence,and the changes of the four parameters of the reducer with different materials under different loading rates are clarified.Finally,it points out the value of the morphologic characteristics of the hysteresis curve in theory and engineering application.
