Providing the claimed performance characteristics of the absorber throughout its life is the most important task that ensures the correct operation of the coupler. Increasing requirements for increasing the speed of movement and the volume of freight traffic make it urgent to increase the reliability of the absorbing apparatus by improving the design of its components and components (housing, friction plates, wedge, etc.).

Keywords: Absorbing apparatus, friction plate, cermet, surface wear, defects in absorbing apparatus

With the growing fleet's increasingly acute problem arises safety and reliability their exploitation as a result of this increase in productivity and accuracy of their technical diagnostics. Urgent task to further improve diagnosis for vehicles is to develop new methods and algorithms highlight the dominant component of the information in relation to a wide class of vehicles. The methods joint time-frequency and wavelet analysis. To isolate the dominant component of the information proposed to use the method of wavelet decomposition. Using vibro acoustic registration nodes vehicles funds allowed to receive signals carrying information about the defects of individual units of vehicles. The proposed decoding algorithms signals have high reliability, allow technical inspection, subsequent monitoring of the technical state of the vehicle. Using vibroacoustic registration of vehicles allowed nodes receive signals carry-ing information about the defects of individual units of vehicles.

 An analysis of new methods and means for a mesurement of parameters of piezoelectric ceramic elements and materials is carried out. These methods and means are based on a digital principle of the construction of devices. An impuls with a linear frequncy modulation therein is used as an signal for exciting. Results of experimental studies on this subject are represented for discussion.     

Keywords: piezo ceramic element, piezo, methods and means of measurement, digital signal processing

В данной статье приводятся примеры стандартных и не стандартных точек контакта с потенциальными клиентами, описаны механизмы их выявления, а также приведены примеры из практического опыта работы авторов по данной теме. Дано определение понятию «клиентоориентированнсть» с точки зрения клиента, и предложены варианты, где применима данная стратегия. Поднят вопрос о качестве обслуживания и что стоит за этим пониманием для клиента, чего он ждет от сферы услуг и на что рассчитывает. В статье рассмотрены этапы анализа точек контакта, приведены примеры влияния этих точек на формирование лояльного отношения клиента к качеству услуг.
