摘要
阐述了水力测功器使用中影响测试精度的几个问题：如转矩一致性检查，正确读数，防止零漂，制动力臂选取，校正臂刀口保护和阻尼油粘度等的影响；并给出了提高测试精度的方法。
This paper introduces several problems affecting test precision in waterpower dynamometer usage. e.g. the check of torque consistency. the correct reading, prevertion of zero-place drift. selection of brilke arm force. protection of correcting arm blade and the dam ping of oil viscosity. The methods to improve test precision are put forward here.
