    Gearing changes its geometry tooth forms during the exploitation which worsen their qualitative characteristics. Some researches believe [(Blagodarny V, 1985)(Schulz V, 1990)] that worn profile becomes steady and keeps this form during the period of exploitation. As it is noted below, tooth profiles do not degenerate around the pitch point and thus it is impossible to synthesize "worn-out" tooth p... View full abstract»

    To protect a driver in the most harmful frequency band, a control strategy for vibration isolating device with minimum stiffness is proposed focusing on motion stability in the large. In the strategy, a model of the device is structured to generate the control criteria in the operation of immenently unstable spring with "negative" stiffness. A control algorithm is considered effecting variability ... View full abstract»

    The safety of operation of designs is now an actual problem. With this purpose at the initial stage of designing it is necessary to provide a significant amount of requirements, frequently inconsistent. For example, it is restrictions on strength, stability, resource of elements of structures, constructive-technological restrictions etc. For many types of structures, for example airframe, the impo...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1213 KB) | HTML iconHTML

    A calculation-experimental method is proposed for estimating the stress intensity factors of modes I and II and determining stresses that act along a crack line before the crack appears. Displacements discontinuities measured at several points at the crack edges are used as initial data. The method is based on the integral representation of the solution describing elastic equilibrium of an anisotr... View full abstract»

    In responsible elements of the planes, bridges and other constructions from metal and composite materials the stress state in the tips of crack is mixed type. At that the conditions of rectilinear growth of a crack are violated as shown by numerous observations and experiments. Thus the problem about determination not only of critical sizes of a crack and critical external loads but also of the pa... View full abstract»
