【Abstract】 Aim The spacer of engines is redesigned as a force transducer while acting as a spacer too on purpose of the test of engines. Methods Strain gauges are used to convert the force into an electric signal. Results The calibration curve of the force transducer is given. Conclusion This kind of force transducer can measure both the static preload on the engine assembling bolts and the dynamic load of engines under working condition.更多还原
