Opis:
This study presents a diagnostic concept, the cybernetic structure and the physical model of the Autonomic Logistics System, a diagnostic sub-system implemented in the Tarpan Honker military vehicle. The system supports the driver in the process of making decisions regarding the vehicle's condition and key operating parameters. The information model reporting on the status and faults of power transmission system components will not identify limit state values. Limit state values will be identified after the vehicle has been tested with an implemented diagnostic system. An RS-485 type communication and data transmission system with linear (serial) half-duplex technology was designed for the proposed monitoring and diagnostic system. The developed data transmission topology (number of transmitters and receivers) accounts for the vehicle's unique structure, operating requirements, system functionalities and structural feasibility. The proposed transmission system supports quick data transfer between modules (devices) monitoring selected systems and mechanisms. The system minimizes the number of sensors and signal cables through the multiple use of measuring sensor signals. The proposed system is an open structure which supports data transfer between control devices supplied by different manufacturers;

Opis:
This article proposes a method and a laboratory setup for testing the fatigue strength of materials with the use of vibration signals and a neodymium fatigue-testing machine. The machine supports non-contact fatigue testing of construction materials, and analyses of bending and torsional behaviour of magnetic and non-magnetic materials at any excitation range. The discussed machine is a non-contact bending device, and when an appropriate adapter is used, it supports analyses of torsional behaviour in determinations of material wear. A neodymium fatigue-testing machine can also be used to evaluate sample deformation by registering amplitude, RMS deviation from equilibriumcalculated values, temperature of sample notch, deflections along the length of the sample, stress at the cross-section of the notch and load applied at the terminal section of the sample. Simplified diagram of a rotating-bending fatigue testing machine, diagrams of biaxial rotating-bending fatigue testing machines, diagrams of a bending fatigue testing machine, displacement range of a material point in the sample induced by neodymium magnets on a double disc, displacement range of a material point in the sample at rotational frequency, displacement range of a material point in the sample at rotational frequency, changes in the sample's notch temperature and displacement amplitude are presented in the paper.
