Vibration Reduction Analysis and Experimental Validation of Speed Control Mechanism of Certain Engine
To address the issue of premature disengagement of rotational speed control mechanism in a certain type of engine starter,a vibration reduction calculation method for the rotational speed control mechanism based on rubber damping material is proposed.This calculation method is applied to optimize the design of the rota-tional speed control mechanism,which is then experimentally validated on an experimental test bench.The re-sults show that the issue of premature disengagement in the optimized rotational speed control mechanism has been resolved,meeting the operational requirements of the aircraft.The analysis of vibration reduction method for the rotational speed control mechanism not only effectively addresses outfield starting issues of the engine,but also reduces maintenance costs of the starter and enhances economic efficiency.Furthermore,the vibration reduction analysis method and experimental validation results offer valuable guidance for the design of similar ro-tational speed control mechanisms.
