可将连杆作为实验应力分析法的一种有价值的应用方面。连杆是发动机活塞和曲轴之间的传动零件,因此在设计时不仅要正确考虑应力问题,而且为了保证两个零件轴承处的润滑性,轴承部分必须有一定的刚度。此外,在设计连杆时还必须考虑制造问题。作为发动机的运动件,连杆影响轴承、曲轴和曲轴箱壁所承受的惯性力负荷,因此,最好在发动机初步设计阶段就考虑合适的连杆形状,以便能够正确设计承受惯性力的零件。
Connecting rod can be used as a valuable experimental aspect of stress analysis. The connecting rod is a transmission part between the engine piston and the crankshaft. Therefore, not only the stress problem should be properly considered in the design, but also the bearing part must have a certain rigidity in order to ensure the lubricity of the bearing of the two parts. In addition, manufacturing problems must also be considered when designing the connecting rod. As a moving part of the engine, the connecting rod affects the load on the bearing, the crankshaft and the wall of the crankcase subjected to inertial forces. Therefore, it is advisable to consider the shape of the connecting rod at the preliminary design stage of the engine so that inertia-bearing parts can be correctly designed.
