摘要： The present disclosure relates to a method of beat tuning in a slightly asymmetric ring-type structure, and can be effectively used to control the beat property of a structure such as a bell, which can be modeled to a slightly asymmetric ring.A method of beat tuning in a slightly asymmetric ring structure includes the steps of establishing an original ring model which simplifies said ring structure, establishing an equivalent imperfection mass model which is equivalent to said original ring model and has at least one or more point masses on an asymmetric ring, determining magnitudes and positions of the point masses in said equivalent imperfection mass model based on mode data of said original ring model, and determining magnitudes and positions of masses which should be added to or removed from said equivalent imperfection mass model in order to obtain desired beat properties.
