摘　　要：讨论了曲柄连杆机构的理论惯性力曲线(力椭圆)和实验惯性力曲线(力8字)的关系,提出在摆架上逐点偏移汽缸进行惯性力实验的方法,得到的实验惯性力曲线完全反映了惯性力的主要参数。在发动机惯性力数学模型的基础上,研究了曲柄连杆机构的合成旋转质量的位置及与往复质量的比值与一次最大惯性力、主趋角、不平衡率的变化关系,讨论了单缸发动机惯性力参数的选择依据。提出了惯性力参数的实验校正算法。The paper studied relations between academic inertial force graph in ellipse and experi mental inertial force graph in “the 8 shape” , presented the inertial force experimental method through shifting cylinder in a testing bed on by a angle every time, the obtained graph and data represent inertial force principal parameters. The angle of rotating mass of a crankshaft-connecting rod and the ratio of rotating mass and to-and-fro mass are important parameters. Based on the inertial force math model in a single-cylinder engine, the paper studied their changing relation graph on maximal inertial force and angle, balance efficiency, discused inertial force parameter design, presented exprimental modifying algorithm for inertial force parameters.
