摘要:
利用MATLAB进行凸轮-活塞发动机的参数设计,建立数学模型,验证其结构可行性; 然后再利用SolidWorks建立三维模型,导入ADAMS进行机构的运动学及动力学仿真。通过对MATLAB的仿真数据分析,得出了活塞位移,速度,加速度等运动参数以及各设计参数对凸轮压力角的影响; 通过对ADAMS的仿真数据分析,得出了滚子接触面受力情况。凸轮作为动力输出机构能够满足发动机工作循环要求,其功率密度及运转稳定性较传统发动机有显著的改善,但是滚子和凸轮之间作用力较大以及磨损比较严重,需要进一步改善。
Abstract:
The parameters of the cam-piston engine were firstly designed by MATLAB to establish the mathematical model and verify the feasibility of the structure; Then, the 3D solid model was constructed by SolidWorks, and imported into ADAMS to conduct dynamics and kinematics simulation; Thirdly, ty analyzing the simulation data of MATLAB, the kinematic parameters such as piston displacement, velocity, and acceleration were obtained, and the influence of the design parameters on the cam pressure angle were analyzed as well; Finally, by analyzing the simulation data of ADAMS, the force of roller contact surface was obtained. It shows that cam, as a power output mechanism, can meet the requirements of the engine working cycle, and its power density and operation stability has been improved significantly compared to that of the traditional engines. However, there is serious wear on the cam due to the large force between the roller and cam, which needs to be further improved.
