钛合金耳片快速设计方法初探

为较快捷地得到以钛合金Ti-6Al-4V锻件为材料的耳片尺寸参数,同时获得合适的承载效率系数,依据相关文献中关于耳片的3种承载效率系数,并结合常规校核公式,将与耳片尺寸参数相关的关联参数由3种统一为1种、即统一为耳片最小径向截面宽度b与耳片内径D的比值,并拟合了对应的承载效率系数曲线。使用本文的3种拟合曲线,可快速、有效地得到耳片参数b/D与承载效率系数的对应关系,达到快速设计接头耳片的目的。

A Simple Approach for Fast Designing the Titanium Alloy Lug

For obtaining size parameter of Ti-6Al-4V forging lug quickly and obtaining suitable load efficiency factor, based on 3 load efficiency factors about the lug with related literature and general calculated formula ,3 associated parameters are united into 1 associated parameter ,that is a ratio of b (the minimum radial section width of lug)to D( the lug inner diameter). And 3 new curves are drew up. By using 3 curves of this paper ,The relationship between the size parameter of b/ D of lug and load efficiency factor can be obtained quickly and effectively. So we can achieve our purpose of fast designing a fitting lug.
