The aim of the project is the systematic study of the impact of tribological stresses on function and durability of helical compression springs and the possibilities for their consideration in the design of the spring and spring usage in the future, to prevent damage as far as possible. The basic results of the pre-project of the mechanism of the damage of the spring due to tribological stress (Impact of tribological stresses on function and durability of helical compression springs, reference number: SCHO 589/6-1 to 6-3, processing time: 01.04.2003 March 31, 2007) and the ongoing Project: Studies on tribological stresses of helical compression springs with the aim of improving friction and wear (reference number: KL 1044/2-1) already indicate a number of important parameters. Also some reference points for a specific engineering design to influence the tribological behaviour of springs are known and applied. However, there are still a number of open questions requiring further systematic research. Focus of the research project is in continuation of the ongoing project the systematic study of the influence of the design of end and transition coils and galvanized and Crapal treated wires on friction and wear, as well as lubricants, the quality of the grinded area of the end coils and the load parameters on friction and wear. By using the additional test results and the FEA Simulation results, the tribological models developed in the ongoing project should be further developed and validated on a wider basis of experimental results.

该项目的目的是系统地研究摩擦应力对螺旋压缩弹簧功能和耐用性的影响，以及在弹簧设计和未来弹簧使用中考虑这些因素的可能性，以尽可能防止损坏。弹簧摩擦应力损伤机理预设计的基本结果（摩擦应力对螺旋压缩弹簧功能和耐久性的影响，参考编号：SCHO 589/6-1至6-3，处理时间：2003年4月1日，2007年3月31日）和正在进行的项目：旨在改善摩擦和磨损的螺旋压缩弹簧的摩擦学应力研究（参考编号：KL 1044/2-1）已经指出了一些重要的参数。此外，一些参考点，为一个特定的工程设计，以影响摩擦学行为的弹簧是已知的和应用。然而，仍有一些悬而未决的问题需要进一步的系统研究。该研究项目的重点是继续正在进行的项目，系统研究末端和过渡线圈以及镀锌和Crapal处理的电线对摩擦和磨损的影响，以及润滑剂，末端线圈研磨区域的质量和负载参数对摩擦和磨损的影响。通过使用额外的测试结果和有限元模拟结果，正在进行的项目中开发的摩擦学模型应进一步开发和验证更广泛的实验结果的基础上。
