【Abstract】 A digital design method was applied to design vibration isolation spring of vibration fluidized bed using SolidWorks and ANSYS software. The vibration isolation spring geometry sizes were determined according to the calculation results of vibration isolation spring stiffness and static strength. It was shown from the comparison results between material mechanics theory, finite element method and experimental measurements:(1)the finite element analysis results were basically identical with the theoretical calculation results, the experimental measurement value>materials mechanics calculation value>finite element calculation value. The designed vibration isolation spring met the technical requirement;(2)Digital design was an accurate and quick method to understand the static characteristics of cylindrical helical spring, which could cut down R&D period greatly.更多还原
