根据关节式曲柄连杆机构独特的运动学、动力学规律,利用UG软件所提供的表达式、规律曲线和优化等模块,给出使主、副气缸的摩擦学特性尽量保持一致的最佳结构参数,并以仿真曲线的方式再现了运动学和动力学特性的变化规律。结果表明:优化结果跟现行许多发动机采用的参数比较吻合,特性曲线的形状也非常一致,主、副气缸的运动学和动力学性能在5%的差异下保持一致;具有主、副气缸运动学上最大相似性的结构参数,可使得主、副气缸的摩擦力和扭矩尽量一致及平稳性更好。
According to the unique kinematics and dynamics laws of the articulated crank mechanism, the optimal structure for keeping the tribological characteristics of the main cylinder and the secondary cylinder as uniform as possible is provided by using the expressions, regular curves and optimization modules provided by the UG software Parameters, and to simulate the way the reproduction of the kinematic and dynamic characteristics of the law of change. The results show that the optimization results are in good agreement with those adopted by many existing engines and the shapes of the characteristic curves are very consistent. The kinematic and dynamic performances of the main cylinder and the secondary cylinder are consistent under the 5% difference. The main cylinder and the secondary cylinder kinematics The structural parameters of the maximum similarity can make the friction and torque of the primary and secondary cylinders as uniform as possible and the stability is better.
