Research on Air Filters’ Low-Order Mode Characteristics Based on Hyper Works

The air filter in the course of their work will produce large vibration by the excitation source from the engine and other incentives will cause severe vibration response when the excitation frequency and its natural frequency close to shorten the life of the filter. Therefore, during the structural design must be modal analysis, its natural frequency to avoid the excitation frequency. This paper describes the application the HyperWorks right air filter of a particular model the steps of the modal analysis, its natural frequency, and the analysis and evaluation.
