(1) Set material properties
According to the actual material of each component, add the material of each gear, planetary carrier, shaft and seal.
(2) Add constraints
Combined with the theoretical model of the rotor system under the action of gear meshing and the actual working situation, the relevant constraint conditions are imposed on the related parts. Because the sun gear of the planetary gear transmission part is connected with the output shaft through the semicircle key, the rotor system part of the shaft and the sealing runway are also connected by the key, so this paper uses Boolean operation for the convenience of research The sun wheel and the output shaft are combined into one component, the rotating shaft and the sealed runway are combined into one component, and the following constraints are added on this basis:
a. A fixed pair is established between the inner gear ring and the frame;
b. Rotating pairs are added between planetary carrier and frame, and between planetary gear and planetary carrier respectively;
c. Parallel and point plane constraints are added between the output shaft of the sun gear and the frame;
d. A coupling pair is added between the output shaft of the planetary gear transmission part and the rotating shaft of the rotor system part;
e. The parallel and point plane constraints are added between the rotor shaft and the seal and the frame respectively.
(3) Add driver and load
Before the simulation analysis, we need to add a drive motor and load to the model, add the drive motor to the planetary carrier, and add the load torque to the shaft of the rotor system.
According to the actual operation requirements, and in order to prevent the impact of transient impact during the start-up process on the simulation analysis, the input speed and load torque are expressed in Adams by step function.
