ABSTRACT

The following paper presents the design of a modern main cylinder in the carding machine with a special bottom with a conical ring. In order to find the optimum dimensions of the cylinder, considering the criterion of minimal deflection, parametric FEM model of the cylinder developed in the ANSYS package has been used. Polak-Ribery conjugate gradient method has been applied for searching the optimal solution. As a result of the performed analyses, reduction of maximum deflection value at approximately 80% has been obtained. Optimal cylinder dimensions enable application of a new textile technology – microfibre carding and improvement in the quality of traditional carding technology of woolen and wool-like fibres.
