Study on suspension problem of high production carding machine revolving flat

For solving the suspension problem of the revolving flat in designing the flat stripping apparatus,the suspension problem is transformed into chain catenary problem,and according to the force analysis of the revolving flat,the unconstrained optimization′s object function of the chain catenary is deduced.It is proved that the chain catenary is composed of the same lines determined by β_1 and β_2 which are the roots of two transcendental equations.The approximate analytical method of using regular broken line and its applicable conditions are given.The support force of the chain catenary is discussed as the design reference of the revolving flat support.The findings are applied to the design of the flat stripping apparatus of high production carding machine,and satisfactory results are achieved.
