我正在为SolidWorks 2020设计一个新的扬声器的角。喇叭几何是由其横断面区域的横断面区域，在我的案例中的嘴上延伸到它的嘴扬声器驱动器安装在前面的矩形开口的圆形部分。
目前我发现维护指数扩张区域的唯一方法（对于大部分 - 确切的形状有一些调整，并且版本2将分成几个有关横截面积扩展的等式的部分部分是c最初和以后每隔10毫米的速度每隔10毫米，并通过这些曲线铺设一次。从圆形到矩形的过渡通过椭圆形拐角在型材上，其尺寸通过眼球的比例和宽度的比例限定并将这些比例送回宽度的等式。使用尺寸直接给了我循环参考问题。曲线的高度由等式驱动的曲线控制，并且允许宽度是所需的横截面积所需的宽度。
我当前的等式集的示例（高度部分由草图中的某些指南曲线定义）：
Example of my sketch with elliptical corners:
And this approach leads to both a wiggly edge on the edge that is not controlled by the equation driven guide curve, and also means that I have to input the values for the elliptical corners by manual guesswork and adjustment (above, the 2.9 in the equation shown).
The wiggly edge of the horn, with the wiggly line of elliptical corners (highlighted with red corresponding to that "cornerwidth" dimension in the sketch above):
You can imagine that when we want to tweak this design a little here or there, to adjust the expansion rate, length of the horn and so on, the whole model falls apart and is very time consuming to reconnect all these cross sections where guide curves no longer connect with profiles and go through each equation to alter the ellipse dimensions and to feed those new denominators back into the equation for the width of the profiles. Generally making any change to this inner surface also causes all of the subsequent modelling operations to fail because they connect to this first surface.
In the ideal world, I would like to find a way in which I can make this process a little less messy, make it so that I can make adjustments without having to rebuild most of the model, maintain control over the cross sectional area expansion of the horn, and generally make my modelling method a bit more elegant, preferably avoiding so many cross sectional almost-copies-but-not-quite sketches if it were possible.
Any tips for other strategies to try? How would you go about this?
Many thanks!
提前谢谢！:)
