ADAMS simulation analysis of the planetary transmission system of electric wrench used for equipment installation

摘要

The electric wrench is widely used in the screw connection of the equipment installation,their transmission system usually use the planet gears.In view of the problems existed in the dynamic simulation of planetary gear system trains,the virtual prototyping technology is used to simulate the dynamic of electric wrench.Firstly,the three-dimensional model of the planetary transmission trains is established by using SolidWorks software.Secondly,the model is introduced into the ADAMS software to carry out the dynamic simulation analysis,the dynamic force of the X axis and the Y axis direction are obtained.The dynamic force is synthesized by using the Matlab software and the dynamic circle force is obtained.Finally,using the model and formula of gear static calculation,the circle force in the static state is obtained.Comparison of the both,the result shows that the dynamic circle force fluctuates around the value of the static circle force according to the rotation period,which fits the characteristics of dynamic changes for acting force.The work lays a foundation for the analysis of the dynamic characteristics of planetary transmission train in the next step.
