Abstract

The relationship between the oil viscosity grade and mechanical vibration of a damping carriage for linear rolling guides was examined based on the sweep excitation method. A dynamic vibration model was proposed to analyze the correlation between the oil viscosity grade and the damping characteristics. Meanwhile, a sweep excitation experimental platform was constructed. The experimental tests were performed on the DS45EA damping carriage, lubricated with the mineral oil of four different viscosity grades (ISO 22, 46, 68 and 150). The response signals of the damping carriage, collected by the PROSIG P8020, were processed through spectrum analyses in three resonant frequency bands. It is proved that the vibration of damping carriage decreases as the oil viscosity increases. Furthermore, the rate of the vibration descent turns to be slow with the oil viscosity increasing, and the vibration magnitude of the damping carriage approaches a constant when the viscosity grade exceeds ISO 70. The results provide a guide to choose the proper oil viscosity for the damping carriage, which is significant for the better performance of linear rolling guides as well as CNC machine tools. The using of sweep excitation method provides a new idea for the study of the damping performance of the damping carriage for linear rolling guides.
