ПРОГНОЗИРОВАНИЕ ПАРАМЕТРИЧЕСКОЙ НАДЕЖНОСТИ ГИДРОУСИЛИТЕЛЯ РУЛЕВОГО УПРАВЛЕНИЯ МОБИЛЬНОЙ МАШИНЫ

An algorithm for forecasting parametric reliability of  hydraulic steering booster during its operation has been developed in the paper. Regression models of output characteristics allowing to determine a reserve  resource for two important devices of the steering booster, namely: flow regulator and control valve have been obtained in the paper. Stochastic characteristics of failure distribution  that may be used while estimating parameters of steering booster reliability are given in the paper.Разработан алгоритм прогнозирования параметрической надежности гидроусилителя рулевого управления в процессе его эксплуатации. Для двух важнейших устройств гидроусилителя – регулятора расхода и гидрораспределителя – получены регрессионные модели выходных характеристик, позволяющие определять остаточный ресурс. Приведены вероятностные характеристики распределения отказов, что может быть использовано при оценке показателей надежности гидроусилителя

Electrical Properties of the Layered Single Crystals TlGaSe2 and TlInS2

In the doped crystals TlGaSe2 and TlInS2, using method of temperature dependencies of DC resistance in the temperature range of 100 – 300 K, the phase transitions at the temperatures of 240 – 245 K and 105 – 120 K were observed. The AC conductance measurements at room temperature indicated the hopping mechanism of carrier transport in the studied samples
