Method, system and engineering machinery for improving arm frame movement stability

The invention discloses a method, a system and engineering machinery for improving arm frame movement stability. The method for improving the arm frame movement stability comprises a step of receiving elastic deformation of an arm frame, and a step of reducing the speed of movement of the arm frame when the elastic deformation exceeds a preset range, in the process of controlling the arm frame to move along a track. The faster the arm frame moves, the larger dynamic load the arm frame bears. Therefore, according to the technical scheme, reducing the speed of movement of the arm frame is beneficial for reducing the elastic deformation of the arm frame and improving the stability of the arm frame.
