The throttle device is an important apparatus for engine control on civil aircraft， and performing kinematics and dynamics analysis of it is the theoretical basis for throttle device design. Firstly， the mechanism is simplified and the kinematics and dynamics mathematical model of throttle device is established according to the motion principle. Secondly， kinematics and dynamics simulations are carried out according to the mathematical model established above to obtain the displacement， velocity and load characteristics of each component of the throttle device in manual and automatic operating modes. Taking the throttle device of specific type of aircraft as an example for simulation， the results show that the simulation error of the throttle angle resolver is no more than 2.3%， the force on the friction clutch and the forward/reverse lever driving torque change in a quadratic curve， and the driving torque of the throttle servo motors changes linearly， reaching a maximum value when the motor starts. Further simulation shows that the change in the length of the control rod of the throttle device has a significant effect on the relationship between the angular displacement of the resolver and the forward lever， as well as the friction clutch force and torque. The research methods and results of this paper can provide reference for large passenger jet throttle device’s kinematic and dynamic analysis， structural design， and selection of throttle servo motors.
