With the continuous improvement of train speeds, it is necessary to find possible problems bearings in time, otherwise they will cause serious consequences. Aiming at characteristics rapid temperature change bearings, a thin film thermocouple sensor was developed measure real-time bearing's rolling elements during operation. Using dc pulse magnetron sputtering technology, Al2O3 film, NiCr NiSi and SiO2 were successively deposited on an aluminum alloy substrate. We studied their...
The research on the thermal characteristics of railway double-row tapered roller bearing is great significance for its structural design and operation monitoring. We established quasi-static mechanical model according to test conditions, we obtained load distribution kinematic parameters bearing. studied temperature under conditions through finite element analysis, which was consistent with results. built a testbed study effects different rotating speeds inner ring, outer roller. results...
At present, piezoelectric sensors are primarily applied in health monitoring areas. They may fall off owing to the adhesive’s durability, and even damage monitored equipment. In this paper, a film sensor (PFS) based on positive effect (PPE) is presented ZnO deposited GH4169 superalloy steel (GSS) substrate using magnetron sputtering. The microstructure micrograph of thin films were analyzed by an X-ray diffractometer (XRD), energy dispersive spectrometer (EDS), scanning electron microscope...
ZnO film is widely used in the field of health monitoring sensors, which has high requirements for piezoelectric coefficient and film-to-substrate adhesion film. In this study, thin films were grown on a GH4169 superalloy steel (GSS) substrate using magnetron sputtering, effects sputtering power, argon-oxygen ratio, pressure studied. The composition, microstructure, crystal orientation deposited under different process parameters analyzed X-ray diffraction (XRD), scanning electron microscope...
The error compensation of Micro Four Axis CNC milling machine is mainly about the basic principle and realization compensation. It also analyzes problems that should be paid attention to in compensation, so as improve effect method superposition additional instruction direct calculation for correcting NC expounded. According modeling four axis machine, theoretical practical relation between tool path instruction, theory actual are given by method, numerical control made using formula, which...
