The invention relates to the technical field of luffing mechanism design, and provides an optimization method of a luffing mechanism, and the optimization method comprises the steps: determining a preset rotation angle of a first included angle and a preset rotation frequency of rotating to the preset rotation angle; starting a variable-amplitude oil cylinder, acquiring an angle difference value between a first included angle after the current rotation and a first included angle after the previous rotation in two adjacent rotations in preset rotation times, and defining the angle difference value as a first change value, the flow difference value between the input flow of the variable-amplitude oil cylinder after current rotation and the input flow of the variable-amplitude oil cylinder after last rotation in two adjacent rotation is obtained, and the flow difference value is defined as a second change value; and when the difference value of the two adjacent first change values is a first preset value, determining that the difference value of the two adjacent second change values is a second preset value. According to the optimization method of the luffing mechanism provided by the invention, the smoothness of the working arm can be improved.
