Abstract

The present invention discloses a signal offset direct-current electric power dynamometer system on the basis of linear filtering processing. The signal offset direct-current electric power dynamometer system on the basis of linear filtering processing comprises a tested engine, a water temperature thermostatic control unit, an engine oil thermostatic control unit, a fuel oil thermostatic control unit, an intelligent oil consumption meter, a torque sensor, a direct-current electric power dynamometer, a DCS speed regulator, a control unit, a power supply processing unit, a power grid, a power analyzer, a signal offset unit, a linear filtering processing unit and a 15 portion of a computer system. Through adoption of the linear filtering processing unit, interference signals in the torque signals of the tested engine may be filtered, so that calculation of the real time power outputted by the tested engine may be more accurate and the testers' accuracy of determining performances of the engine may be improved.

Description

technical field [0001] The invention relates to the field of mechanical testing systems, in particular to a signal-biased DC electric dynamometer system based on linear filter processing. Background technique [0002] Engine bench performance test is a necessary means to measure engine power performance and economic performance. Engine bench test equipment is an indispensable equipment for performance testing, and its level directly affects whether it can faithfully reflect the performance of the engine and whether it can provide the basis for engine design and improvement. Therefore, it plays an important role in the improvement of engine performance and quality. occupies a very important position. As the core of the engine bench test equipment, the dynamometer plays a pivotal role in it. However, the traditionally used hydraulic dynamometer is mainly used to test high-power engines, and its measurement accuracy is low, and the measurement process is difficult to operate;...
