Non-circular Planetary Gear Kinematics And Dynamics Simulation Based On ADAMS

Gear is the most widely used mechanical transmission of a transmission form, circular gear fixed gear ratio to achieve a result which is widely used, but required transmission with Variable Transmission is difficult to meet.Non-circular gear shaft can pass between the two non-uniform motion, and with the CAD/CAM technology continues to evolve and is widely used in automobile, engineering machinery, ships, machine tools and aerospace fields, including non-circular planetary gear mechanism, with its smooth low speed operation, start efficient and compact layout of the advantages of flexible concern. However, the existing non-circular planetary gear mechanism of multi-mode as the internal gear, the paper focused on the external non-circular planetary gear meshing manner of institutions, non-circular planetary gear to the development of a new direction.This paper and summarizes the basic theory of non-circular gear, and then established a non-circular planetary gear pitch model, are outside the non-circular planetary gear meshing kinematics characteristics; based on multi-body dynamics software ADAMS, through virtual simulation technology the establishment of a non-circular planetary gear mechanism of virtual experimental model, according to Hertz theory of elastic collision of the virtual model to determine reasonable parameters of kinematics and dynamics simulation, the actual movement and institutions were compared to verify the accuracy of virtual simulation, and access to the institutional dynamics; according to the dynamic results, based on ANSYS software to simplify the contact analysis of gear to assess whether the occurrence of gear gear tooth fracture and damage caused by such issues as institutional failure; vibration module based on ADAMS/Vibration on vibration analysis of flexible coupling bodies to assess whether the motor gear input will cause the system resonance frequency, while outside the set of points on the target vibration, the frequency response function by the target point.This non-circular planetary gear mechanism patent for utility model laid the foundation for research and extension, while the design and optimization of the organization also has important theoretical significance and practical value.
