Standard Guide for Determining Friction Energy Dissipation in Reciprocating Tribosystems 确定往复式系统中摩擦能量耗散的标准指南
发布日期: 2010-04-01
1.1本指南涵盖并旨在解释往复摩擦系统中记录的摩擦力。本指南适用于任何往复摩擦系统,无论是磨损或微动试验,还是实际的机器或设备。 1.2在分析试验方法中的摩擦结果时,制定了能量耗散指南 G133 平面往复球试验,但它适用于其他ASTM或ISO往复试验。该技术经常用于记录微动摩擦系统中的摩擦响应。 1.3如果受试材料表现出粘弹性,则试样材料可能会在结果中发挥一定作用。本指南适用于不显示粘弹性行为的金属、塑料和陶瓷。 它也适用于润滑和非润滑触点。 1.4以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全和健康实践,并确定监管限制的适用性。 ====意义和用途====== 与竞争摩擦系统相比,许多滑动系统表现出间歇性高摩擦力偏移。然而,当摩擦力或摩擦系数取平均值时,试验数据可能表明两个系统具有相同的摩擦特性,而实际上它们并不相同; 有摩擦 “ 问题 ” 在一个周期性畸变。FED考虑了测试增量中出现的所有摩擦力。这是在指定的测试持续时间内,电偶耗散的所有摩擦能量。它以单个数字捕捉系统的摩擦曲线,可用于筛选摩擦特性的候选偶。 如果往复摩擦系统中使用的摩擦能量值得关注,则该指标以及摩擦记录、平均摩擦系数和力读数的标准偏差会产生最有意义的数据。它是摩擦系统中能量损失的度量。
1.1 This guide covers and is intended for use in interpreting the friction forces recorded in reciprocating tribosystems. The guide applies to any reciprocating tribosystem, whether it is a wear or fretting test or an actual machine or device. 1.2    The energy dissipation guide was developed in analyzing friction results in the Test Method G133 reciprocating ball-on-flat test, but it applies to other ASTM or ISO reciprocating tests. This technique is frequently used to record the friction response in fretting tribosystems. 1.3 Specimen material may play some role in the results if the materials under test display viscoelastic behavior. This guide as written is for metals, plastics, and ceramics that do not display viscoelastic behavior. It also applies to lubricated and non-lubricated contacts. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== Many sliding systems exhibit intermittent high friction force excursions compared to competing tribosystems. However, where friction forces or friction coefficients are averaged, the test data may show that the two systems have the same friction characteristics, when in fact they were not the same; there was a friction “ problem ” in the one with the periodic aberrations. The FED takes into account all friction forces that occur in the test increment. It is all of the friction energy that the couple dissipated in the designated test duration. It captures the friction profile of a system in a single number that can be used to screen candidate couples for friction characteristics. If the friction energy used in a reciprocating tribosystem is of concern this metric along with the friction recording, average coefficient of friction, and standard deviation of the force readings, produces the most meaningful data. It is a metric of the energy loss in a tribosystem.
