Shenyang auto sping factory is a large enterprise specialized in auto leaf spring , torsion bar and axle for light duty vehicle 沈阳汽车弹簧厂是专业生产汽车钢板弹簧、扭杆弹簧的大型企业。
It can simulate the complete stress cycle including the initial stress in the assembly process , by composing stresses of two stages 同时通过使用各阶段应力合成的方法，能较好的模拟考虑钢板弹簧装配阶段预应力在内的完整应力循环。
The enterprise uses the 60sizmn material produced by state - owned large - scale enterprises and other premium grade material , which is even superior to the national standard 该企业自创建以来，一直使用国家大型企业生产的60i2mn材料和高于国家标准的高等级材料生产各种钢板弹簧。
The fea assembly model was built according to the distortion of the leaf spring in the former phase in ansys apdl . the load case was simulated with contact of loading head and leaf spring 根据装配阶段各簧片的变形情况，并利用装配阶段所建模型的参数化语言程序建立钢板弹簧总成的有限元模型。
Leaf spring is an elastic component often used in dependent - type suspension on modern vehicles , and its stress and fatigue strength characteristics are vital to the reliability and security in the vehicle riding 钢板弹簧是汽车非独立悬挂装置中的一种常用的弹性元件，其强度特性和疲劳特性对车辆行驶的可靠性和安全性有重要意义。
Compared with the present calculating methods , the software which consists of developing environment , implementing technology and basic functions proves to be both more feasible and practical 此运行软件包括：开发环境，实现技术及基本功能，并利用该软件与现行钢板弹簧计算方法相比较，充分证明了该软件在计算上的可行性与实用性。
Our main products include redirector dowel , armor plate spring dowel , armor plate spring stationary rings series . there about hundred products of three series which occupancy 100 % at faw market 现我公司主导产品为中重型卡车配套生产转向节主销、钢板弹簧销系列及钢板弹簧吊环系列。现有三大系列百余种产品，在一汽集团内市场占有率达到100 % 。
It is feasible to predict the fatigue life of the structure in the critical location when the s - n curve of the fatigue life applied . the meanings and conclusions can effectively instruct the design of leaf spring system 最后对模型采用疲劳寿命的s - n曲线法计算能较准确的预测出疲劳破坏发生的区域及结构的疲劳寿命，在实际应用中对钢板弹簧的设计有重要的指导意义。
The meanings and conclusions can effectively instruct the design of leaf spring system . the results of the test and simulation reveal that based on the fe analysis , the fine friction between leaves is no obvious influence upon the structure stress distribution 本文通过使用有限元法的结构应力分析计算和疲劳试验研究表明，钢板弹簧簧片间良好的摩擦状况对结构的应力分布无明显影响。
In this paper , first the present various methods to calculate vehicle leaf - sprig are discussed and analyzed , on the basis of which a vehicle leaf - spring calculation and design software is developed by making use of c + + 6 . 0 system under the windows 2000 在此基础上，开发了一种汽车钢板弹簧计算与设计软件。即在微机windows2000中文系统环境下运用visualc + + 6 . 0编译工具所开发出来的汽车钢板弹簧计算与设计软件。
