In addition, in some existing vibration simulation test tables, the design structure is complex, the volume is overlarge, the processing and manufacturing cost is overlarge, and the parameters which can be reacted by the vibration test are incomplete and the adjustability is poor. Vibration detection inspection platforms related to agricultural electromechanical equipment are not yet available in the market. Based on the vibration experiment table, the invention tries to design the multifunctional vibration experiment table for the agricultural machinery equipment, so that the vibration experiment table provides needed parameters such as excitation frequency, vibration amplitude and the like for the optimal design of the agricultural machinery part products, and simultaneously provides a universal multifunctional vibration experiment table for teaching and scientific research.
