Passenger vehicles in Manual for Assessing Safety Hardware (MASH) crash testing are required to be representative of the modern vehicle fleet and practical worst-case impact scenarios. The objective of this paper was to identify potential updates for standard test vehicle selection criteria for MASH as well as develop a preferred strategy for performing future standard test vehicle reviews. Representative vehicles were documented using sales data, and registration and crash data were observed to validate the primary use of sales data. Curb weights were plotted against cumulative market share of new vehicle sales to identify the 5th and 95th percentile “practical worst-case” weights of 2,800 lb and 5,850 lb, respectively, consistent with MASH philosophy. Suitable test vehicle options were found at the 5th percentile weight; however, a pickup near the 92.5 percentile weight (5,400 lb) was recommended to ensure vehicles are both representative of the fleet and obtainable for crash sites. MASH test vehicle specifications were recommended based on a review of geometrical and inertial properties of candidate vehicles near these target weights. Potential mid-size test vehicles were also explored, and four vehicle classes (two mid-size car and two crossover utility vehicle [CUV] classes) were identified as test vehicle candidates. Research on vehicle impact behavior of mid-size cars and CUVs are desired to determine impact behavior of each vehicle with different roadside hardware. Future revisions to MASH test vehicle selection criteria were outlined and should use analysis and attributes of new vehicle sales.

推荐的测试车更新,用于评估安全硬件手册

评估安全硬件手册中的乘用车(MASH)碰撞测试必须代表现代车辆和实际的最坏情况下的冲击情况。本文的目的是为MASH的标准测试车辆选择标准确定潜在的更新,并为执行未来的标准测试车辆审查制定一种首选策略。使用销售数据记录了代表车辆,并观察了注册和崩溃数据以验证销售数据的主要用途。将路缘重量与新车销售的累积市场份额作图,以确定第5个和第95个百分位数的“实际最坏情况”重量分别为2,800 lb和5,850 lb,这与MASH的理念一致。在第5个百分位数的重量中找到了合适的测试工具选项;但是,皮卡的重量接近92.5%(5,建议使用400磅)的汽车,以确保车辆既能代表车队,又能在坠机现场获得。根据对这些目标重量附近的候选车辆的几何和惯性特性的审查,建议使用MASH试验车辆规格。还研究了潜在的中型测试车辆,并确定了四个车辆类别(两个中型车辆和两个交叉多功能车[CUV]类)作为候选测试车辆。需要研究中型汽车和CUV的车辆碰撞行为,以确定每辆具有不同路边硬件的车辆的碰撞行为。概述了对MASH测试车辆选择标准的未来修订,并应使用新车辆销售的分析和属性。根据对这些目标重量附近的候选车辆的几何和惯性特性的审查,建议使用MASH试验车辆规格。还研究了潜在的中型测试车辆,并确定了四个车辆类别(两个中型车辆和两个交叉多功能车[CUV]类)作为候选测试车辆。需要研究中型汽车和CUV的车辆碰撞行为,以确定每辆具有不同路边硬件的车辆的碰撞行为。概述了对MASH测试车辆选择标准的未来修订,并应使用新车辆销售的分析和属性。根据对这些目标重量附近的候选车辆的几何和惯性特性的审查,建议使用MASH试验车辆规格。还研究了潜在的中型测试车辆,并确定了四个车辆类别(两个中型车辆和两个交叉多功能车[CUV]类)作为候选测试车辆。需要研究中型汽车和CUV的车辆碰撞行为,以确定每辆具有不同路边硬件的车辆的碰撞行为。概述了对MASH测试车辆选择标准的未来修订,并应使用新车辆销售的分析和属性。四个车辆类别(两个中型车和两个交叉多功能车[CUV]类别)被确定为测试车辆候选对象。需要研究中型汽车和CUV的车辆碰撞行为,以确定每辆具有不同路边硬件的车辆的碰撞行为。概述了对MASH测试车辆选择标准的未来修订,并应使用新车辆销售的分析和属性。四个车辆类别(两个中型车和两个跨界多功能车[CUV]类别)被确定为测试车辆候选对象。需要研究中型汽车和CUV的车辆碰撞行为,以确定每辆具有不同路边硬件的车辆的碰撞行为。概述了对MASH测试车辆选择标准的未来修订,并应使用新车辆销售的分析和属性。
