LMS EXPERIMENTAL MODAL ANALYSIS OF COMPRESSOR VIBRATION ISOLATION COMPONENT FOR FOOD REFRIGERATING UNIT

The experimental modal analysis was conducted on the vibration and isolation component of compressor in food refrigerating unit using LMS Test.Lab software.The natural frequency,natural mode of vibration and damping ratio of the first four orders were obtained by comparing LSCE with PolyMAX algorithm.The research results are important for the vibration and isolation design of compressors in food refrigerating unit,and also provide the significant basis for the research on vibration and noise reduction in large-scale food refrigerating unit.
