摘      要：Spiral springs have a wide range of applications in various *** a result of the complexity of friction,few theoretical analyses of spring belts under static loading have been carried *** the piecewise smooth property of the whole contact area,a simplified static model of spiral springs under loading is established in this ***,three main stress and friction distribution areas of the spring belt are proposed,namely,internal,transitional,and external *** the outermost side of the spring is not subject to any pressure,a recursive method is adopted from the outside to the *** model provides the parameter conditions,i.e.,the internal and external forces are independent or ***,the case that the whole contact region of the spring belt has one subregion,two subregions,and three subregions is *** model gives a theoretical basis for the parameter optimization of spiral springs.
