汽车爆胎应急安全装置结构设计-机械毕业设计资料
摘 要
随着汽车与高速公路的普及，车辆爆胎导致的交通事故频发，严重威胁生命财产
安全。因此，汽车轮胎爆胎安全问题备受关注。爆胎应急安全装置当做一种新型汽车
安全产品，能有效处理由各种爆胎原因引起的安全变故既保障安全又带来经济效益。
本文应用仿真分析和试验证验相结合的方法，因而研究爆胎应急安全装置和其轮辋的
工作特性，并分析轮胎爆破后的零压行走的状态，确保该装置能够在爆胎后依旧能够
发挥其保护的作用。研究内容简洁明了，旨在提高汽车行驶安全。
(1)根据其爆胎的应急安全装置的工作原理和汽车轮辋轮廓特性分析，认定并完
成了该装置的总体方案设计，紧接着对其进行了结构设计。通过 ANSYS Workbench 执
行静态工作特征分析，验证了设计的合理性与可行性。
(2)对应该爆胎应急安全装置的动态工作特性，对其进行了准静态分析，并模拟
了轮胎在地面上运转一周的一个动态进程，结果显示，装置的整体应力主要分布在螺
栓连接端部。
(3)研究爆胎后轮胎零压行走时，爆胎应急安全装置的受力情况，通过仿真分析
发现，轮辋在零压状态下经受了轮胎的重要载荷。这意味着该装置在轮胎零压行走进
程中能够持续的稳定，难以断裂，高效防止轮胎掉落，进而确保爆胎车辆的安全驾驶。

ABSTRACT
With the popularization of cars and expressways, traffic accidents caused by vehicle tire blowout occur
frequently, seriously threatening life and property safety. Therefore, the safety problem of automobile tire
burst has attracted much attention. As a new type of automobile safety product, the emergency safety
device of burst tire can effectively solve the safety accidents caused by various reasons of burst tire, which
not only guarantees the safety but also brings economic benefits. This paper uses the method of simulation
analysis and test verification to study the working characteristics of the tire burst emergency safety device
and its rim, and analyzes the state of zero pressure walking after the tire burst, so as to ensure that the
device can still play its protective role after the tire burst. The research content is concise and clear,
aiming at improving the safety of automobile driving.
(1) According to the working principle of the emergency safety device of the tire burst and the analysis of
the profile characteristics of the automobile rim, the overall scheme design of the device is confirmed and
completed, and then the structural design is carried out. The rationality and feasibility of the design are
verified by the analysis of static working characteristics by ANSYS Workbench.
(2) According to the dynamic working characteristics of the tire burst emergency safety device, we carried
out a quasi-static analysis and simulated a dynamic process of tire running on the ground for a week. The
results showed that the overall stress of the device was mainly distributed in the bolted connection end.
(3) The stress situation of the emergency safety device of the tire burst when the tire is walking under zero
pressure after the tire burst is studied. Through simulation analysis, it is found that the rim bears the main
load of the tire under zero pressure. This means that the device can remain stable during the zero pressure
walking of the tire, is not easy to break, and effectively prevents the tire from falling off, thus ensuring the
safe driving of the vehicle with a burst tire.
