Design and Optimization of Spatial Cylindrical Cam of Synchronous Movement Mechanism of Opposed-piston Axial Cylinder Engine

The optimization design of space cylindrical cam synchronization mechanism of opposed piston in axial cylinder two-stroke engine is studied. In order to optimize the performance of engine, a model of space cylindrical cam is established, the pressure angle and space cylindrical cam profile are optimized and designed, and the movement law of engine piston is optimized. The performance parameters of the engine under different piston displacement curves are calculated by using GT-power simulation software. And the influence of piston displacement curve on the performance parameters of engine is analyzed. The calculated results show that the movement law of piston is optimized and the engine performance is improved by optimizing the space cylindrical cam profile. With the change in the direction of piston displacement curve, the performance of engine is first increased and then begins to decline. An optimal design method of space cylindrical cam of synchronous motion mechanism in the opposed piston engine is obtained.
