This article shows the results obtained during the implementation of a portable diagnosis system to the maintenance routines of the passenger vehicles and permanent track of the Metro train, which made it possible to evaluate such aspects as: safety, comfort and technical condition of the track-vehicle interphase. The reports given in this evaluation allowed the identification and the arrangement of the track sections according to its technical condition, relating thus the track and vehicle condition parameters to the estimators connected with the passenger vehicles dynamics.

A method to establish duty cycle was proposed based on wheel loader operating characteristics and features. Firstly, wheel loader operating characteristics, energy consumption and power distribution rules were summarized theoretically. Wheel loader energy consumption rules were explored through operating test. The features were extracted from testing data which can represent wheel loader operating rules. Finally, the duty cycle was composed according to the rules features arose in the actual operating test. The duty cycle will provide support for data files for hybrid wheel loader power system matching, computer simulation and dynamic analysis. Furthermore, the duty cycle will be helpful for traditional wheel loader dynamic matching, simulation analysis and numerical optimization.

Abstract This paper presents the results of analyses of ecological synthetic oil samples during an operating test. The operating test of oil was performed within cooperation of the Department of Transport and Handling and Slovnaft, a. s. (joint stock company). The analysis of ferrographic samples was performed in the laboratory of the department, and other analyses were done in an accredited Wearcheck Laboratory at Almásfüzitő, Hungary.

In this study, a novel inertial piezoelectric rotary motor is proposed and its operating principle is introduced. The dynamics model of the motor is presented. From the model, the equations of the natural frequency and mode function of the motor are obtained. Using these equations, the natural frequency and mode function of the motor are investigated and chosen. A model machine of the motor is made and the operating test of the motor is done. The test results illustrate the working principle of the motor and analytical calculations. The motor structure is quite simple and is favourable to further miniaturize the piezoelectric rotational motor.
