使用滑裙活塞的原因是：短行程发动机需除去部分活塞裙部，从而为曲轴的平衡重让出空间。
One reason for the slipper piston is that, on the short-stroke, over square engine, the piston skirt had to be cut away to make room for the counterweights on the crankshaft.
以连续梁模型作为曲轴受力分析的基础，分析了平衡重对曲轴所受弯矩的影响。
On the basis of continuous beam model the effect of fitting counterweights on the bending moment of crankshaft was analysed.
当曲轴配置平衡重后，可以通过调整飞轮惯量，使系统的自振频率不但不下降，还能略有提高。
In a certain inertia of the system, the natural frequency can be increased a little by adjusting the inertia of the flywheel when the crankshaft is fitted with a balancer.
曲轴上平衡重的安装减小了曲轴所受的弯矩，但也影响了主轴承载荷的大小和分布。
The counterweight is installed on the crankshaft for reducing the bending moment on it, but it will influence the magnitude and distribution of the main bearing load.
