Series A 42(3), pp.179-190The concept of the vibration reduction via position change of the vibration absorbers was introduced in this study. A rigid body plate was taken as the main body. Each of the four corners of the main body was supported by a cubic spring to simulate the transverse-rotate-rotate nonlinear vibrations. Two point-mass shock absorbers were suspended under the body. The positions of these two absorbers could be adjusted to achieve the best vibration reduction effect. The method of multiple scales was used to obtain analytic solutions to this vibration system. Both analytic and numerical results were compared to verify the impacts on system vibrat
