Test Bench Design Of The Micro-turbine Engine

In view of the existing micro turbine engine design a test bench, and then analysis of the measurement principle. Selection the sensor for measurement of exhaust temperature, engine vibration in the running, rotational speed, the exhaust dynamic and static parameters, and determine the installation method.According to characteristic of thrust measurement using CREO based on the piezoelectric force sensor design a six degrees of freedom thrust measuring platform, in the case of normal operation of the micro turbine engine can sense the condition of the thrust in all directions, and then according to the characteristics of the thrust measurement platform confirm the calibration principle. And then based on ANSYS make a modal analysis for the whole thrust measuring bench, get the inherent frequency.Analysis the whole ground test bench about the micro turbine engine and a start-up process are given, and then simulation analysis of the entire process. Finally, analysis of the problems of test bench in the trial may appear, formulate corresponding solutions.
