Subbotina M. Dynamics and methods of calculation of impulsive reductors

The object is dynamics of impulsive reductors (IR) with a free-wheel mechanism (FWM) as a mechanical system of a variable structure. The aim is creation of the complex of theoretically substantiated methods of impulsive reductors dynamic analysis. The methods are elasticity theory, vibration theory, theory of mathematical analysis, solution of transcendental and system of differential equations, strain measurement; mathematical statistics. Newness: the methods of dynamic analysis of IR with FWM and lever motion transforming mechanism have been developed; the greatest dynamic loads on FMW have been determined; the generalized mathematical model of IR taking into account units elasticity and the model of IR with a vibratory motor drive have been developed and investigated; computation technique and designing of IR taking into account units elasticity according to the given average gearing ratio and movement variation factor has been developed; algorithm and computation program in MathCAD of complete alternation cycle dynamics of IR units movement of any kind have been developed. Field of application is designing of IR as machines drives, where large gearing ratio and given movement variation factor are required.
