Modeling of the Process of Winding Shells of Composite Materials

Abstract

The issues associated with the technology of winding a tape of composite materials. The peculiarities of technological processes of shaping blanks of solids of revolution method of winding. The definition of tape drive mechanism used for winding shells and the basic classification signs. Presents a generalized kinematic diagram of the mechanism for moving and winding the yarns and tapes. Considered dynamic phenomena occurring during the process of winding and storing yarn. Selected methods of process control of the winding tape. Noted for active and passive devices in the mechanisms of regulation of speed and yarn tension. Devices are classified according to the degree of automation of the process of moving and coiling of the tape. Mathematical dependences describing the dynamic characteristics of the process teach-equipped with the necessary fullness of friction interaction and elastic components of the mechanism as a whole. On the example of calculation of the correction device, consisting of elastic and plastic elements, shows how to provide dynamic resistance in a tape drive fur the lowland, to avoid resonance phenomena of the winding process of the ribbon and as a consequence of the defects in the blanks. Using mathematical equations and initial conditions the calculation of amplitude-frequency characteristics. The results of numerical simulation are presented in the form of gra-ficou containing extreme points, corresponding to the resonance phenomena in the mechanism. The results of Chis-industrial simulations confirm the accuracy and correctness of the used mathematical relationships. The proposed mathematical dependence on the results of the calculations can be used in the construction of algorithms of computer-aided process control of winding the flax-Ter. In the framework of the presented algorithm a block diagram of the system adaptation.-of the MOU and management of the coiling process, which includes elements of automatic speed measuring of replacement and deflection of the thread.
