本文叙述了单轴多列多缸主、副连杆活塞机构的运动学、动力学、平衡及曲轴疲劳强度计算。运动学、动力学按未经近似简化的精确公式计算,并考虑了副连杆销的运动惯性力对动力强度的影响。平衡重可以任意布置,以研究其对主轴承负荷的影响。轴承负荷及曲轴疲劳强度的计算均按简支梁进行。所编制的程序亦适用于并列、叉型连杆活塞机构内燃机的计算。 This paper describes the kinematics, dynamics, balance and crankshaft fatigue strength calculation of single-shaft and multi-cylinder multi-cylinder master and slave piston. Kinematics and dynamics are calculated according to exact formulas without approximate simplification, and the influences of the kinematic inertia force of the secondary connecting rod pin on the dynamic strength are considered. Balance weight can be arbitrarily arranged to study its impact on the main bearing load. Bearing load and crankshaft fatigue strength are calculated according to simply supported beams. The procedures compiled are also applicable to the calculation of internal combustion engines with parallel and fork linkage piston mechanisms.
