To address the vibration and noise issues in traditional swashplate engines, a collaborative shaft constraint drive structure design scheme was proposed. The major parameters of the swashplate engine were determined through the piston stroke equation, and a 3D model of the collaborative shaft swashplate engine was built in SolidWorks software. To compare the dynamic characteristics at the output end with the straight guide groove structure, rigid body simulation was conducted by Adams software. To investigate the real constraint situation of the collaborative shaft, a combined rigid-flexible coupling simulation was performed using Ansys-Adams. The results indicated that under the rated operating conditions with a speed of 1 200 r/min, the collaborative shaft swashplate engine exhibited a decrease by 4.16 r/min in the deviation of the output speed from the peak compared with the direct groove swinging plate engine. The peak values of positive and negative angular accelerations were also reduced by 4 375.11 rad/s2 and 3 032.46 rad/s2, respectively. The former can be considered as a substitute for the latter. After flexible modification of the coupling shaft, although the flexible deformation of the collaborative shaft caused vibrations and other unfavorable factors within the first 0 s to 0.035 4 s of the simulation, the collaborative shaft still effectively constrained the system.
