ABSTRACT
摘要
The increase in truck or full frame vehicles in the market has led to unfavorable collision loss experience trends, due in part to the lack of adequate frame repair options. Prior to the incorporation of passive restraints in light duty trucks and sport utility vehicles, frame repair was considered by the vehicle manufacturers and theinsurance industry to be a generally accepted practice.
卡车或全帧车辆的增加在市场趋势导致了不利的碰撞损失经验,部分是由于缺乏足够的帧修复选项。之前的被动约束在轻型卡车和suv,肋骨修复被认为是由汽车制造商和保险行业是一个公认的做法。
With the advent of air bags, forward portions of front frame were redesigned to act as part of the energy management for passive restraint deployment. Several manufacturers weresufficiently concerned with the difficulties of restoring the impact performance of this area of the frame, that they recommended that this area should not be repaired, and furthermore if damaged, the entire frame should be replaced. However, after manufacturers began to adopt Hydro-forming for frame side rails, frame horn and rear frame side rail sectioning sanctioned by some manufacturers has become an accepted repair industry procedure.
与安全气囊的出现,提出部分前面框架被设计作为能源管理被动约束部署的一部分。一些制造商weresufficiently关心困难的恢复这一地区影响性能的框架,他们建议这方面不应该被修复,而且如果损坏,整个框架应该被取代。然而,在制造商开始采用Hydro-forming rails框架方面,框架角和后车架纵梁切片批准一些制造商已经成为一种公认的修复工业过程。
If frame damage is such that sectioning is neither practical nor recommended, either due to the economic value of the vehicle or structural integrity concerns by the manufacturer, respectively, full frame replacement is usually pursued. However, this solution is not always practical. Currently in several states titling regulations make frame replacement impractical resulting in the disposition of these trucks as total losses.
如果框架损坏,切片既不实际,也不推荐,因为车辆的经济价值或结构完整性问题的制造商,全帧分别替代通常追求。然而,这种解决方案并不总是实用。目前在几个州标题规定使帧替代不切实际导致这些卡车的性格总损失。
This problem could be partially solved if truck frames were more repairable than they are currently. If frame sectioning in other areas besides the horns, such as in the middle of the vehicle, or if some frame materials were less sensitive to heat from stress relief, there might be fewer trucks in the total loss salvage pool, which could result in fewer non-recommended frame repairs performed.
可以部分解决这个问题如果卡车框架比他们正在修复。如果帧分割在其他领域除了角,如中间的车,或者一些框架材料对热量减压不太敏感,可能会有更少的卡车全损打捞池中,这可能导致更少的non-recommended框架执行维修。
This paper would encourage vehicle manufacturers to design and produce frames that are more repairable and/or can more easily be partially or fully replaced. Repair statistics and research examples are provided in support of this position.
本文将鼓励汽车制造商设计和生产框架更修复和/或更容易可以部分或全部替代。提供了维修统计和研究例子支持这一立场。
INTRODUCTION
介绍
The purpose of this paper is two-fold, 1. Create awareness in the OEM and supplier communities of the problems in the field related to the current situation regarding truck frame repair and replacement options and 2. Provide recommendations for future designs for potential improvement in repair opportunities:
本文的目的是双重的,1。创造意识的OEM和供应商社区相关的问题在这一领域有关车架修复和替代选择的现状和2。为未来潜在的改进设计提供建议修复机会:
The current situation, (i.e. since the mid 1990's), has had several outcomes:
当前形势下,(即从1990年代中期起),有几个结果:
1. Frame repair information in the collision repair industry has resulted in adoption of the prevailing attitude that frames from trucks containing crush zones for passive restraint deployment can only be repaired for minor damage in strictly limited areas and conditions or, in some cases, not at all.
1。帧碰撞修复行业维修信息导致采用普遍的态度,从卡车框架包含粉碎区为被动约束部署只能修复轻微损坏或在严格限制地区和条件,在某些情况下,根本没有。
2. Some partial replacement procedures are available.
2。部分替代程序是可用的。
