| Abstract: | A high speed data sampling and processing system applied to investagation of engine valve train is introduced. The data sampler of the systemmakes use of engine crank angle signals as sampling pulse, it can control thesampling range accurately and make it possible to sample in designated range ofengine working cycle, thus meeting the requirement for high speed sampling andprocessing of dynamic data. Some distinguished data processing methods are alsointroduced in this paper, e. g. digital filtering, continued fraction integration etc.Several data sampling and processing examples are given combined with the measurement of engine valve train's dynamic parameters. |
