Dynamic Analysis and Test of 2-DOF Vibration Isolation System of a Refrigerator Compressor
摘要
Abstract
A refrigerator compressor is simplified to a 2-DOF vibration isolation model. Considering vertical and rolling movement patterns, the dynamic equation of the model is established based on Lagrange method. The amplitude-frequency response curves with parameter variation are plotted. The effects of spring stiffness, support spacing, eccentricity and system damping on the force transmissibility are analyzed. By means of the modal experiment method, the natural frequencies of the first two orders are measured and compared with the theoretical calculation results, and the reliability of the theoretical analysis is proved. This work provides a reference for structure optimization and vibration and noise reduction design of refrigerator compressors.关键词
