vehicle wheel brake of the spread of the estimated by mathematical modelling.

摘要

this invention is a vehicle wheel brake, the temperature rise of the magnetic lock (lock vapor) phenomenon of the vehicle driving conditions and the device lock the brake oil pressure, and the effective volume rate (effective bulk modulus) and other parameters of automobile braking system, and the as the development of the lock of the occurrence of system. at the same time, in order to ensure the performance of the braking system in order to ensure the progress of the vehicle wheel brake to predict the spread of mathematical modeling of the structure.;in order to this invention.brake fluid, the absolute viscosity and hydraulic pipe of the hydraulic pipe and the length of the internal diameter of the wheel brake unit to supply oil into the calculation of the hydraulic pipe to the hydraulic pipe to the model; the model of uc758ud574 planned unit flow, through the wheel. lake of the brake chamber to flow into the brake line pressure and the brake and the opponents to the calculation of the static model of the wheel brake wheel brake; the static model in the planned to the static brake rubber and the time constants and the standard rate of lake volume ratio the calculation of the brake rubber is the rubber to the dynamic model of the government; the oak to model the government planned to brake the wheel acceleration and the rotation angle, and the fixed part of the mechanical energy of the rotor and the wheel brake disk. method and drum lining and friction heat occurs in the calculation of the thermal response type government;the wheel brake when the temperature of the friction, and relative speed of friction coefficient. the model can calculate the pressure of the brake liquid and the effective height of the gas in accordance with the calculation of the effective volume of the ubaa8ub378ubd80), including, in the. .
