In the present study, the unstable vibration occurring in a hydraulic servomechanism controlled by a throttle valve is treated. The observed vibrations are classified into three modes, the frequencies of which are different from each other, according to the disturbance added to the throttle valve. Two modes of vibration, having higher frequencies, are called mode I_A and mode I_B vibrations, the remaining of lower frequency is called a mode II vibration. The vibration properties of these modes are considered to be closely related to the dynamic characteristics of the thrust force acting on the throttle valve. The simulation of modes I_A and I_B is carried out considering the dynamic characteristics of the thrust force. The simulation result agrees well with the experimental result, in the wave form, frequency and the configuration of the limit cycle.
