摘　　要：针对电磁式谐波摩擦传动柔轮在磁场中发生变形,使气隙随时改变这一现象,引入气隙函数的概念,并根据薄壳弹性变形理论,将传动的柔轮简化为圆柱壳体,建立了在电磁场力作用下柔轮的静力分析模型。该方法由于考虑了柔轮的变形导致的磁密的变化,能够更确切地描述电机径向电磁力的特性及柔轮的受力与变形规律,为电磁式谐波电机的设计及强度校核提供了更为可靠的理论依据。In view of the phenomenon that an electromagnetic harmonic friction driving flexspline will deform in a magnetic field,this deformation will change the airgap at any moment,a concept of airgap function was introduced.And based on thin-shelled elastic deformation theory,simplifying the driven flexspline to a column shell,a model was built and used to analyse the static force of flexspline affected by electromagnetism.Due to this method has considered flux density change caused by flexspline formation,it can precisely describe the characteristics of the radial electromagnetic force,the force and deformation rule of flexspline.It provides a more reliable theoretical basis for harmonic electromagnetic motor structure design and strength check.
