Object of research - contact problems tribomechanics for cylindrical bodies with smooth and ribbed surfaces and plates with curvilinear contours, particulate strengthened thin elastic elements of varying stiffness. The effective method of construction and approximated numerical solution of systems of singular integral equations with cores of Hilbert and logarithmic cores in problems about contact interplay of cylindrical bodies with smooth and ribbed surfaces is advanced at their coupling to a backlash or tension. The numerically - analytical collocation method investigates influencing on a state of stress of a plate of the shape of a hole,friction, value of a tension, shape of the disk and angle of its turn in a problem about an inexact contact of an infinite isotropic plate to a curvilinear hole and hard disk with angular points, and in problems about a partial strengthening of curvilinear contours of plates by thin elastic members - shape of a hole, physical-geometrical parameters of a strengthening and way of their accommodation contoured, external loading, stuff of a plate. The miscellaneous models of a member of a strengthening are investigated:elastic rod, elastic line with final flexural stiffness and elastic line with zero flexural stiffness. Is rotined, that for thin elastic members at , usage of model of an elastic line with zero flexural stiffness results in simplification of input equations and outcomes, which one can be used with precise sufficient engineering accuracy. The updated mathematical model of a spline of a hub and arbor is constructed, ground which one formulates new contact problems for plates with particulate strengthening circular profiles, and also the numerically - analytical algorithms of problem solving about transmission of efforts to plates through elastic curvilinear thin lines are advanced. The methods of the solution of contact problems for isotropic cylindrical bodies with smooth and ribbed surfaces are transferred on orthotropic plates with an elliptical hole. The obtained outcomes make the idealized basis of calculation of profile splines in transmissions of rotary motion. Product Description popup.authors popup.nrat_date 2020-04-02 Close
