螺旋压缩弹簧和牵簧的术语

[中文适用范围]： 开发了以下推荐的做法，以帮助工程师和设计师准备主要类型的螺旋压缩和拉伸弹簧的规格。它仅限于对项目的简洁介绍，以促进弹簧制造商和弹簧用户之间对成品弹簧的主要实际要求的充分理解。当需要更高的精度并且增加的成本合理时，可以获得更小的公差。有关弹簧设计的基本概念和许多细节@，请参阅《SAE 信息报告手册关于螺旋和螺旋弹簧的设计和应用@ SAE HS 795@》，该手册可从沃伦代尔的 SAE 总部@ PA 15096 获取。 统一方法用于指定设计信息的信息请参见螺旋弹簧@ SAE J1122 的典型设计检查表。考虑两种类型的螺旋弹簧：适用于一般汽车以及机动车辆悬架的热卷绕压缩弹簧。 b.一般汽车用途的冷缠绕压缩弹簧和拉伸弹簧。本推荐做法根据 SAE TSB 003 的规定使用 SI（公制）单位。基本原理：J1121 已经过审查和更新，以反映当前的行业标准。 [外文原描述]： The following recommended practice has been developed to assist engineers and designers in the preparation of specifications for the major types of helical compression and extension springs. It is restricted to a concise presentation of items which will promote an adequate understanding between spring manufacturer and spring user of the major practical requirements in the finished spring. Closer tolerances are obtainable where greater accuracy is required and the increased cost is justified.For the basic concepts underlying the spring design and for many of the details, see the SAE Information Report MANUAL ON DESIGN AND APPLICATION OF HELICAL AND SPIRAL SPRINGS, SAE HS 795, which is available from SAE Headquarters in Warrendale, PA 15096. A uniform method for specifying design information is shown in the TYPICAL DESIGN CHECK LISTS FOR HELICAL SPRINGS, SAE J1122.Two types of helical springs are considered:aHot coiled compression springs for general automotive use as well as for motor vehicle suspensions.bCold wound compression and extension springs for general automotive use.This recommended practice uses SI (metric) units in accordance with the provisions of SAE TSB 003.Cross Reference: ASTMA227/A227M,ASTMA228/A228M,ASTMA229/A229M,ASTMA230/A230M,ASTMA232/A232M,ASTMA401/A401M,ASTMA679/A679M,HS84,HSJ795,J1122_201608,J217_201604,J230_201604,J461_201801,TSB003
