摘要

除材料的强度比外，螺纹啮合长度和导孔直径的大小决定了成形母螺纹螺栓连接的准静态强度。针对不同的螺纹类型和螺纹尺寸，进行了不同螺纹啮合长度和螺纹重叠的拉出试验，以验证所需最小啮合长度的新评估方法。在设计过程中，通过计算完美成形螺纹与待测螺纹的应力比，考虑了螺纹重叠问题。

Experimentelle und rechnerisch validierte Methode zur Bestimmung der Mindesteinschraubtiefe von Schraubenverbindungen mit gefurchtem Mutterngewinde Experimental and computationally validated approach for determining the minimum length of thread engagement for bolted joints with formed female threads

Beside the strength ratio of the material the length of thread engagement and the size of the pilot hole diameter determine the quasi-static strength of bolted joints with formed female threads. Pull-out tests with varied lengths of thread engagement and thread overlapping are carried out for different thread types and thread sizes to validate a new evaluation approach for the required minimum length of engagement. By means of a stress ratio of a perfectly formed thread and that of a thread to be evaluated the thread overlapping is taken into account in the design process.

期刊介绍： Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing. Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline. Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
