美国海军陆战队车辆腐蚀/耐久性行驶试验方法综述

为保证美国海军陆战队轮式战术车辆实现20 a服役寿命的目标，美海军研究办公室海军材料科学与技术部资助海军水面作战中心、阿伯丁试验中心等部门，研发了评估轮式车辆系统的车辆腐蚀/耐久性行驶试验方法。该方法通过响应美国海军陆战队在军用车辆腐蚀和任务剖面的特殊要求，对美国陆军基于商业标准的车辆试验成果加以完善，利用全寿命周期费用降低计划项目的基础数据，制定了1～20 a各年度累计腐蚀质量损失控制目标，规定了评价车辆老化状况的0—4级腐蚀等级标准，并开展了长达15 a的验证试验。研究表明，车辆腐蚀控制目标可采用研发的腐蚀/耐久性行驶试验方法实现；试验场车辆的腐蚀状况与实际服役地域车辆的腐蚀状况具有等价性；车辆腐蚀/耐久性行驶试验方法可作为车辆采办的有力工具，可考核验证车辆寿命能否达到20 a的服役期指标。

Review on Vehicle Corrosion/Durability Driving Test Method of US Marine Corps

In order to ensure that the wheeled tactical vehicle of US Marine Corps (USMC) can achieve the 20 years of service life, the Naval Materials Science and Technology Department has funded the Naval Surface Operations Center, Aberdeen Testing Center and other departments to develop a vehicle corrosion/durability driving test method for assessing the wheeled vehicle system. The method in response to the special requirements of the US Marine Corps in military vehicle corrosion and mission profile improved the vehicle test results based on commercial standards, established the annual cumulative corrosion loss control target of 1~20 years based on the basic data of the whole life cycle cost reduction project, stipulated the 0~4 corrosion grade standard for evaluating vehicle aging, and conducted the verification test up to 15 years. The study shows that the vehicle corrosion control target can be achieved by the developed durability driving test method; the corrosion status of the vehicle is equivalent to that of the vehicle in the actual use area; the vehicle corrosion/durability driving test method can be used as a favorable tool for vehicle acquisition to prove whether the service life of vehicle can reach the service index of 20 years.
