Simulation of dynamic phenomenons in nonlinear parametric systems with kinematic coupling and backlash

For verification analytical results of solving inner dynamics on nonlinear parametric system was built simulation model of stiff bearing external spur gearing, which respects except variable stiffness - given change numbers of tooth in mesh - also influence of geometrical departure evolventy curve from ideal profil side tooth. Simulation model of system with two degrees of freedom covers region of normal mesh, tchnological backlash and areas of inverse mesh
