Abstract

Subject of Research. The paper deals with research of a damping system with elements having an ability to be linear work-hardening – work-hardening elements. This system transforms kinetic energy of moving progressively straightforward technical object into deformation energy and work of friction force. Example with element in the form of rigid-plastic conical shell is analyzed. Method. Research was carried out theoretically and was based on theory of thin shells and hypothesis of Kirchhoff-Love. In addition, Coulomb law modeling friction between both contact surfaces and Saint-Venant yield criterion are used. Main Results. Technique of strain-stress state examination in conical shell being deformed by rigid cone in view of friction force was generated. Practical Relevance. Results of research give the possibility to calculate strain-stress state of conical shell at indentation of rigid cone into it. These results open the door for future research of damping systems with plastic element in the form of a conical shell. 


Keywords: damping system, conical shell, linear work-hurdling material, thin shell theory
