Because the crank only swings back and force within limit, therefore, the dead center in circular motion is overcome, and the crank can make power in the most ideal angle range. 由于曲柄只作有限度的来回摆动,从而克服了圆周运动中的死点,并能在最理想的角度范围内作功。
Through analysis of simulation results, found the center mass of crank and linear eccentricity have big influence to piston side pressure and inertia force. 通过动力学仿真结果的分析,发现曲柄连杆机构偏心距及曲轴质心位置对机构中的动态力有较大影响。
Modifying mass parameters ( center of mass and mass) of crank have different effects on the cylinder block, especially on the arrangement of counter weighting. 改变曲轴的质量特性参数(质心的位置、质量的大小),对机体的干扰力有不同程度的影响,其中质心的位置对惯性力平衡有较大的影响。
