ATPD-2354 Revision 10 Verification Test, Disc Brake Version Only (16 NOV 06) Article Test of High Mobility Multipurpose Wheeled Vehicle (HMMWV-ECV)
Abstract
CONTRACT REQUIRED OBJECTIVES: 1.1. To verify the adequacy and suitability-for-intended-use by the government of draft ATPD-2354 Rev. 10 (disk brake sections only). 1.2. To assess the ability to differentiate performance and other characteristics between the OEM supplier(s) and alternative sources without the need to do actual on-vehicle testing. 1.3. To propose updates, improvements, or corrections to draft ATPD-2354 Rev. 10 (disk brakes sections only). 2. SCOPE: 2.1. Conduct comparative testing for three test products: OE (a.k.a. baseline), Brand X , and Brand Y. The OE product and Brand X were furnished by TARDEC-TACOM, Brand Y was furnished by LINK. 2.2. Conduct three tests on each product for inertia-dynamometer test procedures and six or twelve tests or measurements for sample testing (no dynamic loading or braking events involved). 2.3. Perform engineering and statistical analysis to determine the adequacy of the different tests to differentiate between/within the three products. 2.4. Use vehicle or hub-end ratings and components to ensure consistent and repetitive test conditions. 2.5. Use OE-type of hardware and brake components for all testing. 2.6. In order to capture different characteristics critical to the proper field service of the brake pads and rotor combination, an assortment of tests was conducted to evaluate physical, performance, durability, and noise properties of the different products tested. The tests conducted were developed as part of the CRADA agreement 05-019 represented by Leo P. Miller for TARDEC-TACOM and Timothy Duncan and Carlos Agudelo for Link Testing Laboratories, Inc. 2.7. For the purposes of this subject report, the term "significantly" shall be interpreted to mean the assessment of significant difference between the three products is based on statistical evaluation using analysis of means or hypothesis testing to validate the conclusions with a confidence interval of 95% and an a sigma-value of 0.05.
