This study investigates non-linear dynamic scaling laws of the rotating thin-wall short cylindrical shell.The study is significant that it guides the design of non-linear scaled models.By introducing the geometric non-linear item,the method of governing equation analysis is employed to establish the non-linear scaling laws.Both natural frequencies and single-point excitation responses of rotating cylindrical shell are investigated.The applicability of scaling laws of the rotating thin-wall short cylindrical shell is verified numerically.In addition,the scaling laws of linear and non-linear vibration are compared.The analytical results indicate that the scaled model designed by non-linear scaling laws are more restrict than that of linear scaling laws,and can predict the characteristics of the prototype with a good accuracy.
