惯性测力计试验过程

[中文适用范围]： 本推荐实践源自联邦机动车辆安全标准 135 车辆测试协议，作为单端惯性测功机测试程序。它在受控和可重复的环境中测量制动输出、摩擦材料的有效性和拐角性能。测试程序还包括后制动器驻车制动器输出性能的可选部分。当使用适当的制动硬件和测试参数时，它适用于 FMVSS 135 涵盖的车辆的制动弯道。此程序适用于 GVWR 不超过 3500 公斤的所有乘用车和轻型卡车。此程序的目的是在与 FMVSS 135 车辆测试程序相对应的条件下了解制动角组件的性能。 [外文原描述]： This document derives from the Federal Motor Vehicle Safety StandardDetails (FMVSS) 105 and 135 vehicle test protocols as single-ended inertia-dynamometer test procedures. The test sequences enable brake output measurement, friction material effectiveness, and corner performance in a controlled and repeatable environment. This SAE Document also includes optional sections for parking brake output performance for rear brakes with hydraulic or Electric Park Brakes (EPB). It applies to brake corners from vehicles covered by the FMVSS 105 and 135 when using the appropriate brake hardware and test parameters. The FMVSS 135 applies to all passenger cars and light trucks up to 3500 kg of gross vehicle weight (GVWR). The FMVSS 105 applies to all passenger cars, multi-purpose vehicles, buses, and trucks above 3500 kg of GVWR. This document does not include testing for school bus applications or vehicles equipped with hydraulic brakes with a GVWR above 4540 kg. This document does not evaluate or quantify other brake system characteristics such as wear, noise, judder, ABS performance, or braking under extreme temperatures or speeds. This document does not include minimum performance requirements. Consistency and margin of pass/fail of the minimum requirements related to stopping distance or equivalent deceleration levels of the FMVSS 105 or FMVSS 135 vehicle test can be assessed as part of the project in coordination with the test requestor when using the appropriate vehicle information and vehicle dynamics modeling. Nevertheless, this procedure and its results do not replace the vehicle-level test to demonstrate compliance with FMVSS for hydraulic brake systems or other mandatory regulations (e.g., ECE R13H or ECE R13). Towing and trailering applications are not part of this document and require a separate assessment per SAE J2807.
