摘要
介绍了测功法甩负荷试验中功率测量、数据处理及积分计算的要点，对试验的计时零点及功率变送器等可能造成误差的有关因素进行了全面分析，提出了对策措施，推导出了简捷的变送器惯性误差修正公式。
The essentials of power measurement,data processing and integration calculation during load rejection test using dynamometry are introduced,the relevant factors of error caused possibly by timing zero point and power transducer etc.during testing are analyzed in an all round way,and the corresponding countermeasures are raised.Finally,the simplified correction formula for inertia error of transducers is derived.
