摘　　要：针对高速大功率工作机械的调速进行了液力方式和变频方式的对比分析,对于调速的经济性,不能只看调速范围的大小,还要考虑工作机械负荷工况的要求。调速方案的选择要综合考虑调速区间及其对应的负荷变化范围、运行维护的经济性以及长期工作的可靠性。齿轮式偶合器适用于高速范围的调节,液力行星齿轮装置则兼有调速范围宽、调速效率高的特点。在高速大功率应用场合,液力调速仍然是一类经济可靠的解决方案。The comparing analysis was done for high speed and big power working machines variable speed application with hy-drodynamic and variable frequency drive. For the economics of speed control,the variable speed range should be considered,as well as load conditions requirements of working machines. When selecting speed control program,the range of speed control and corre-sponding load conditions,the economics of operation and maintenance and the reliability of long-term work should be considered com-prehensively. Gear type couplings are suitable for high speed range adjustment. Hydrodynamic planetary gear unit has the characteris-tics of wide variable speed range and high efficiency of speed control. In the situations of high speed and big power,hydrodynamic vari-able speed control is still a class of economical and reliable solution.
