1.1本试验方法涵盖使用加速计在轮廓测量车辆上建立惯性基准测量和记录车辆行驶表面的轮廓。 1.2本试验方法使用惯性基准面和行驶表面之间的距离测量以及惯性平台的加速度来检测表面高程沿仪表车辆行驶长度的变化。为了满足特定等级，传感器应满足精度要求，计算的轮廓应满足该等级的规范。 1.3测量值表示使用本文所述设备和程序从参考移动平面测量的过滤轮廓。 获得的剖面测量值应与经过相同过滤的实际高程测量值一致。选择适当的滤波允许用户获得用于预期数据处理的适当波长信息。 1.4以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 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。 第7节给出了具体的预防信息。 ====意义和用途====== 使用带有惯性基准面的仪器车辆测量车辆行驶表面，为获取行驶表面轮廓数据提供了一种令人满意的方法 (1) . 可以处理轮廓数据，通过模拟产生其他设备的输出。这可以在线实时完成，也可以作为后处理进行计算。一些可以模拟的设备包括路表 (2) ，各种直尺装置 (3) ，轮廓图， (4) ，以及摊铺机和研磨机。参考文献中给出了各种设备及其剖面计算机程序的比较 (5, 6) . 还可以记录原始数据或剖面数据，以便稍后进行数据处理，并通过更复杂的数据处理程序进行分析。

1.1 This test method covers the measurement and recording of the profile of vehicular-traveled surfaces with an accelerometer established inertial reference on a profile-measuring vehicle. 1.2 The test method uses measurement of the distance between an inertial plane of reference and the traveled surface along with the acceleration of the inertial platform to detect changes in elevation of the surface along the length being traversed by the instrumented vehicle. In order to meet a particular class, the transducers shall meet accuracy requirements and the calculated profile shall meet the specifications of that class. 1.3 The values measured represent a filtered profile measured from a moving plane of reference using the equipment and procedures stated herein. The profile measurements obtained should agree with actual elevation measurements that are subjected to the same filtering. Selection of proper filtering allows the user to obtain suitable wavelength information for the intended data processing. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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. Specific precautionary information is given in Section 7. ====== Significance And Use ====== The measurement of vehicular traveled surfaces using an instrumented vehicle with an inertial plane of reference provides a satisfactory method for acquiring traveled surface profile data (1) . The profile data can be processed to produce, by simulation, the outputs of other devices. This can be done on line in real time or can be computed as a post process. Some of the devices that can be simulated include road meters (2) , various straightedge devices (3) , profilographs, (4) , as well as pavers and grinders. Comparisons of various equipment and their profile computer programs are given in reference (5, 6) . The raw data or the profile data can also be recorded for data processing at a later time and for analysis by more complex data processing procedures.
