补充资料：动力机械：内燃机动力学
研究内燃机运转中的力学现象的科学。其主要任务是研究分析内燃机运转时各主要零件的运动规律及其受力情况﹐用以作为内燃机零件设计﹑计算的依据。它还研究这些力对内燃机动力装置的影响及其消减方法。内燃机动力学的主要内容为曲柄连杆机构运动学﹑曲柄连杆机构动力学和内燃机平衡分析等。
曲柄连杆机构运动学 研究曲柄﹑连杆﹐尤其是活塞的运动规律。活塞作周期性往复运动时的位移
、速度
和加速度
可用下述各式近似求算
式中为曲轴转角﹔ 
为曲轴旋转角速度﹔
为曲柄半径﹔
为曲柄半径 与连杆长度
之比﹐即 ＝ /
曲柄作回转运动﹐连杆作复杂的平面运动。连杆的运动往往被简化分解为随活塞组的往复运动和随同曲柄的旋转运动。
曲柄连杆机构动力学 研究分析曲柄连杆机构(见曲柄滑块机构)在运动中力的生成﹑传递和输出。作用在曲柄连杆机构上的力有曲柄连杆机构运动时产生的往复惯性力和离心惯性力﹐以及内燃机气缸内的气体压力。
