This paper mainly studies the clutch control problem in the refitting process of an old track vehicle.The Lagrange equation is used for mathematical modeling of the clutch combination process,and the optimal control algorithm is adopted to propose the optimal control strategy for the clutch.It carries out simulation calculation based on MATLAB software to verify the rationality of its strategy formulation.Through simulation comparison,it can be concluded that the clutch control strategy based on the optimal control algorithm can effectively reduce the slipping wear work generated when the clutch is combined on the premise of ensuring the proper gear shifting impact degree.
