 note = {This paper investigates the nonlinear modeling of the liquid hydrogen turbopump for rocket engine. The degree of freedom of ball is introduced and its contact/separation from the inner or outer race is considered. The dynamic response of the turbopump shaft in the unsteady condition with fast acceleration which reaches more than third critical speed is numerically investigated, and the occurrence of the asynchronous vibration component is observed, and the characteristic of the asynchronous vibration component is discussed. This result is compared with the experimental result, and it shows the capability of the explanation of occurrence of the specific asynchronous vibration component observed in the experimental data., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: PA1610052000},
