Aiming at the problems of low replacement efficiency and high dependence on lifting during the use of hydraulic cylinder test support frame,a new open frame improvement scheme is proposed.The simulation analysis is carried out to accurately design the stiffness of the frame,and the universal wheel is designed at the bottom of the frame to facilitate the transition of the calibration process.At the same time,the strength of the frame is checked by simulation analysis,so that it has a high safety margin.Compared with the existing frame,the improved frame has better usability and reliability.
