号摩擦试验机 6000 rpm 步进功率测试

[中文适用范围]： 本 SAE 推荐实践旨在作为标准测试@的定义，但可能会经常发生变化，以跟上经验和技术进步的步伐。在考虑其使用时应牢记这一点。 SAE 2 号摩擦试验机用于评估使用汽车变速箱油的自动变速箱板式离合器的摩擦特性。它还可用于对湿摩擦系统进行耐久性测试。本文件的具体目的是定义 6000 rpm 步进功率测试，用于评估湿摩擦系统性能随功率水平变化的变化。该程序使用 6000 rpm 的初始接合速度，旨在作为供应商和最终用户共同使用的标准程序。摩擦系统的供应商或用户选择的唯一变量是：摩擦材料 B．流体 C.反应板 在报告使用该测试的结果时，必须清楚地识别这三个变量。如果本文件中描述的任何测试参数或系统硬件发生变化，除了摩擦材料@测试流体@或反应板@之外，数据可能不会报告为使用本文件获得的数据。此程序并非旨在评估初始系数或磨合特性。有关此信息@请参阅 SAE J2490 SAE No. 2 摩擦试验机 VT 测试。 [外文原描述]： This SAE Recommended Practice is intended as the definition of a standard test, but it may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering its use.The SAE No. 2 Friction Test Machine is used to evaluate the friction characteristics of automatic transmission plate clutches with automotive transmission fluids. It can also be used to conduct durability tests on wet friction systems.The specific purpose of this document is to define a 6000 rpm stepped power test for the evaluation of wet friction system performance variation as a function of power level. This procedure uses an initial engagement speed of 6000 rpm and is intended as a standard procedure for common use by both suppliers and end users.The only variables selected by the supplier or user of the friction system are:aFriction materialbFluidcReaction platesThese three variables must be clearly identified when reporting the results of using this test. If any of the test parameters or system hardware as described in this document are changed, other than the friction material, test fluid, or reaction plates, the data may not be reported as having been obtained using this document.This procedure is not intended to evaluate the initial coefficient or break-in characteristics. For this information, refer to SAE J2490.
