Abstract: This paper introduces a direct-acting centrifugal speed limiter (DCSL) to address large braking errors and low sensitivity in ratchet-claw centrifugal speed limiters. A triggering model for the DCSL is established through dynamic analysis and simulated in MATLAB, revealing relationships between release speed, centrifugal block mass, speed regulating spring (SRS) stiffness, and SRS pre-compression. The DCSL mathematical model is derived and validated via ADAMS dynamic simulation. An experimental platform is built, and MATLAB models experimental data, confirming the mathematical model's reliability with errors between 0.11% and 8.89%. The DCSL exhibits fast response and a wide speed limitation range, offering a new design approach for high-sensitivity, low-error centrifugal speed limiters.

Keywords: Direct-acting centrifugal speed limiter, Dynamic analysis, Simulation analysis, Data processing, Experimental verification.
