Three approaches are compared for the estimation of the bending and torsional stiffnesses of the wire structures. Two of them are used still in engineering practice. The third approach is based on the representation of the layered wire structure in the form of a coaxial system of anisotropic cylindrical shells interacted by forces ofpressure and friction. Based on this approach, the formulas were obtained for determining the rigidity and flexibility matrices. The formulas for calculation of bending and torsional stiffnesses of the conductors and cables were also obtained with regard to their internal structure and interaction of wire layers each other.
Сравниваются три подхода к оценкам крутильных и изгибных жесткостей проволочных конструкций. Два из них традиционных, используемых до сих пор в инженерной практике. Третий подход основан на представлении слоистой проволочной конструкции в виде коаксиальной системы анизотропных цилиндрических оболочек, взаимодействующих между собой силами давления и трения. На основе этого подхода получены формулы для определения матриц податливости и жесткости проволочных конструкций. Получены также формулы для оценки жесткостей проводов и тросов на кручение и изгиб с учетом их внутреннего строения и взаимодействия повивов между собой.
