RATIONALE 基本原理Because of drawing reproduction and possible confusion and for clarity, Figure 1 SAE J577 Vibration Test Machine drawing has been removed. Only the vibration requirements are shown.由于复印图纸可能不够清楚而引起混淆同时为了确保清晰，图1-SAE J577震动测试仪图纸被移除。只显示震动测试要求Aiming adjustment tests were added to help insure amiability of the head lamp and insure the lamps are secure during operation of the machine.为了确保头灯的稳定性及其在机械操作过程中的安全性，增加了瞄准调整测试Visual service aiming was added to include beam definition. This will allow the beam to have adequate definition so that it can be visually aimed at the factory and in the field.增加了目测瞄准并赋予光束以定义，从而使得在工厂内部或实际场地中都可以对其进行目测瞄准Photometric intensities in Tables 1 and 2 were left as is after the Special Purpose Vehicle Committee reviewed the necessity to have them changed. It was decided that the intensities were sufficient for the present.特种车委员会经过商议之后决定保留表1和表2中的光度标准，留待日后加以更改。目前该标准是合适的FOREWORD 前言This SAE Recommended Practice is intended as a guide toward standard practice, but may be subject to frequent change to keep pace with experience and technical advances. Hence, its use where flexibility of revision is impractical is not recommended. SAE推荐操作方法旨在为标准化操作提供一个样本，但考虑到实际经验和技术革新是在不断发展的，因此有必要灵活采用1.
