摘要

本研究分析了四分之一汽车制动模型，以确定车轮滑移率(λ)对汽车制动过程中摩擦系数(µ)的影响。当滑移比λ ~ 1时，摩擦系数最小;最佳滑移比值为0.18 ~ 0.2时的最大摩擦系数。车辆动力学模型在ABS制动研究中应详细考虑制动的动力学方面以及轮胎与路面轮廓的相互作用。本研究采用CarSim软件对某工业厂房车辆制动系统进行仿真;对ABS和非ABS两种制动系统进行了仿真。考虑和分析了制动距离、减速度和制动压力的结果，以选择适合所设计卡车工况的制动系统。

Simulation of Electric Truck Brake System Operating in Industrial Plants

This study analyzes the quarter car braking model to determine the effect of the wheel slip ratio (λ) on the friction coefficient (µ) during the braking of the car. The friction coefficient reaches a minimum when the slip ratio λ ∼ 1; maximum friction coefficient at the optimal slip ratio value from 0.18 to 0.2. Dynamic Model of the vehicle in the ABS brake study should consider in detail the dynamic aspects of braking and the interaction between the tire and the road profile. CarSim software is used in this study to simulate the braking system of a vehicle operating in industrial plant; Simulation is performed on both cases of ABS and non-ABS braking systems. The results of braking distance, deceleration, and brake pressure are considered and analyzed to select a suitable braking system for the operating conditions of the designed truck.
