内燃机驱动的各种工作机械及运输工具,普遍存在扭转振动问題。有时,这种振动负荷可达到像机械破坏的程度,因而早就引起人们广泛的重视,从理论上认识并在实践上为减小其危害提出了种种办法 以汽车、拖拉机为代表的陆地运输机械,传动系的刚度较大(与内燃机—螺旋桨驱动系相比),随着工作速度的提高,传动系统的扭振问题日益尖锐。普遍采用了曲轴扭振减震器和离合器减震器,在国外新机型所用的减震器也大多已是标准化的部件。随着电子计算机的普遍推广应用,进一步提高了传动系统扭振计算和减震器设计计算的工作效率和计算精度。 本文在参阅有关资料的基础上综述了设置减震器的必要性及其参数选择,并介绍了一些常用结构及其使用效果,可供有关同志参考。
Various internal combustion engine-driven machinery and transport tools, the prevalence of torsional vibration problems. Sometimes, this vibration load can reach the degree of mechanical destruction, which has aroused widespread attention, in theory, and in practice to reduce the harm put forward all the way to cars, tractors, represented by land transport machinery , The rigidity of the transmission system is larger (compared with the internal combustion engine-propeller drive system), and as the working speed increases, the torsional vibration problem of the transmission system becomes increasingly acute. Crankshaft torsional vibration absorbers and clutch shock absorbers are commonly used. Shock absorbers used in new foreign models are also mostly standardized components. With the general popularization and application of electronic computers, the work efficiency and calculation accuracy of torsional vibration calculation and shock absorber design and calculation of the transmission system are further improved. This paper reviews the information on the basis of the necessity of setting the shock absorber and its parameter selection, and introduces some common structures and their effects, for the comrades reference.
