Analysis on Influence Factors of Automobile Seat Headrest Mandatory Test
-
摘要: 详细分析了目前汽车座椅头枕的两项国家强制性法规试验项目：对于头枕吸能试验，找出影响试验结果的主要因素，并分析每种因素影响机理；对头枕静强度试验进行分析，将试验过程划分为3个典型阶段，详细阐述了每个阶段的形成过程以及影响试验结果的因素，在大量试验的基础上，列举了试验中出现的若干种典型曲线，并进行了原因分析。所得结论可以更有针对性的改进座椅头枕及座椅结构，也可为工程师在产品设计阶段和试验结果分析上提供有价值的参考。Abstract: Two national mandatory regulatory test items about seat headrest are investigated in detail. For the energy dissipation test, main factors which influent test results are listed, and the influence mechanism of each factor is analyzed. For the static strength test, test curves are obtained and analyzed; the test process is divided into three typical phases, the formation process of each phase and main factors which influent test results are demonstrated in detail. Several typical test curves are listed based on a great quantity of tests, the formation causes of the typical test curves are analyzed. The analysis conclusions above can improve structural desgin of seat and seat headrest, also can provide valuable reference for engineers in design phase of product and test result analysis.
