Abstract: An element harmonic balance method based on finite element method is proposedin this paper and is used to solve nonlinear dynamic response problems. Different from generalharmonic balance method, such harmonic balance equations airs established in finite element level,making the method advantageous in both finite element method and general harmonic balancemethod. The applications of finite element method can extend the solving range to complex engi-neering structures, and the application of harmonic balance...
