Analyzing The Braking Vibration Of Inertia Brake And Developing The Inertia Brake Test Platform

The inertia brake is a new kind of braking device, which is designed according to the inertia-brake principle, and it integrates brake, shaft coupling and can interconvert between them. As a result of its unique dynamic windproof function, it is applied in the harbor machinery more and more widely.This article takes the Lagrange equation as the principle, establishes mathematics modeling to the inertia brake vibration when it brakes, then simulates it with MATLAB. This paper educed the relation equations between, which are the inertia brake's friction coefficient of the brake ring and the friction disk, the mean radius, the braking force, rotation inertia of the driving top and the spline shaft, spiral climbing angle of the brake's concave-convex helicoid, the mean effort radius of the concave-convex helicoid, elasticity coefficient of the spring, quality of the driving top and the spline shaft, rotations inertia of the brake's rotation part besides the driving top and the spline shaft, suppresses sleeve. Provides the theory basis for the inertia brake structure optimization.Through establishing three mathematics models including the movement equation of the mechanical and electrical transmission system, the control of the load and the sliding in stable status, direct-current-brake of AC motor, this paper ascertained the range of the frequency value of drive motor and the efficiency of transmission system, calculated the efficiency of load motor in stable status and the moment of load motor in braking. This paper completed the design of the mechanical part of inertia brake test platform and provides a tool for the measurement of the inertia brake parameters.
