摘要
论述了某型号柴油机扫气泵系统中的弹性轴，在转速２７７５～５５５０ｒ／ｍｉｎ（即主机２５０～５００ｒ／ｍｉｎ）范围内负载运行情况下，扭转时应变波时域谱及频率域谱的测试。文中还得到扭转剪切应力。测试结果比较满意，达到了预期目的。
This paper deals with the measuring about time zone spectrum and frequency spectrum of strain for the elastic shaft of scavenging pupm in the diesel engine. The measured results when the elastic shaft is running at 2775~5550 rpm (the major engine is 250~500 rpm) were given, and the torsional stress was given too. The results are satisfied for fault diagnosis.
