Dynamic Characteristic Analysis and Experimental Study of a Direct-Acting Centrifugal Speed Limiter Based on Adams–Ansys

For the newly designed direct-acting centrifugal speed limiter, this paper employs a joint simulation method using ADAMS 2019 and ANSYS 2024, and combines the experimental data to analyze the dynamic characteristics and structural strength reliability of the speed limiter. The results show that the error between the simulated trigger angular velocity and the set value is only 1.31%, and the error with the mathematical model is 3.23%. The maximum structural stress is only 2.62% of the material yield strength, and the first six natural frequencies ranging from 201 to 377 Hz are much higher than the elevator operating frequency band, eliminating the risk of resonance. The relative errors between the experimental test data, theoretical models, and simulation results are all less than 6%, verifying the accuracy and reliability of the design. The speed limiter exhibits sensitive triggering and excellent dynamic stability, providing a methodological reference for the design and verification of elevator safety components.
