简介:冰壶螺旋运动雕塑

这本书的灵感来源于数学家和艺术家约翰·埃德马克(John Edmark)在动态雕塑、可变形物体以及隐藏在自然几何中的令人惊讶的结构方面的迷人作品。我一看到他curling spirals, I knew I had to figure out how to make one for myself. The way the sculpture curls so naturally when you fold the sides open is so mesmerizing and lifelike. In the future, I think it would be really cool to make this interactive object into more than just a wooden frame-- a geometric octopus tentacle maybe?

Step 1: Materials

1/8" plywood

胶水(我用热胶水和白工艺胶水)

Scissors

Non-stretchy fabric (for joining the wooden pieces together)

Step 2: Download Files

I've included an Adobe Illustrator AI vector file and a PDF file that you can use with your laser cutter.

这种设计有两个对称的侧面,每一面由18个木块组成,这些木块连接在一起形成一个几何螺旋。每件18件都是相同的不规则四边形,但大小不同。这些碎片完美地排列在一起,以便在任何两个连续的碎片之间,较大碎片的较短边与较短碎片的较长边长度相同。

第三步:激光切割

I used a Universal Systems laser cutter to laser cut the design out of 1/8" plywood.

Since there's so many pieces, and the order in which you glue them together is very important, I suggest stacking them together in order of size so that you can keep track of them easily. I made 2 stacks: 1 stack for each side of the spiral, and 18 pieces in each stack. The included design file is organized so that you can easily see the order of the pieces.

Step 4: Assemble the Two Sides of the Spiral

Now it's time to join the pieces together using glue and strips of fabric.

用织物剪刀将织物剪成1/2英寸厚的条状。你需要一条足够长的带子来夹在每一件衣服之间。每件衣服的三个边上都有一个织物接头,但在螺旋的最末端的四件衣服除外。

我试过两种胶水:白色工艺胶和热胶。我用的白色工艺胶是粘性胶。在尝试了这两种方法后,我发现热胶比白工艺胶更容易,也更省时。不过,我只会使用热胶,如果你有一个高热胶枪,使胶水保持融化足够长的时间,让你有时间建立织物接头。用低温胶枪,胶水会冷却,硬化得太快。如果你没有高热胶枪,就用白色工艺胶。

这些碎片完美地排列在一起,以便在任何两个连续的碎片之间,较大碎片的较短边与较短碎片的较长边长度相同。在两个木片之间的布条上均匀地涂上一层胶水,然后用力按压直至干燥。全部18件都这样。当你完成螺旋的一边,然后以同样的方式组装另一边,除了这次螺旋应该在相反的方向卷曲。注意,在第六张图片中,有两个螺旋线彼此朝向相反的方向。我们想把两个螺旋夹在一起,并把它们连接在外面的脊椎上,这样织物的接缝就在里面互相面对。

Step 5: Glue the Two Sides Together

Now comes the tricky part: joining the two spirals together along the outer spine. Cut more 1/2 inch thick fabric strips. Take one spiral and glue the fabric strips along the outer spine, so that half of the strip is connected to the spiral, and the other half is hanging off, as in the first picture. Take the other spiral and place it on top of the first spiral, with fabric joints facing each other inside, so that they both line up nicely and form the two sides of the sculpture. Then fold in half of the fabric strip that you glued along the outer spine, add some glue on top of the flap of fabric, and press the other spiral on top so that they are hinged together. Repeat this for each of the 18 pairs of wooden pieces, until the whole spiral is joined.

第6步: Viola! You're Done!

要卷曲和展开螺旋,只需将一只手放在螺旋底部的螺旋两侧(螺旋末端最大的一块),然后将手向彼此移动或远离彼此(就像打开和关闭一本书一样)。当你的手靠得更近以闭合螺旋两侧之间的间隙时,螺旋将展开。把你的手移开一点会使螺旋卷曲成一个球。

问题9个月前的第6步

This is amazing! Very very cool! we're doing a project in uni that's supposed to be some type of kinematic structure. I stumbled upon this "tail" like structure somewhere on Pinterest and after some research, i found this post and i gotta say, this is just wow, very good explanation and not as hard as i thought it was to build it. How do you think the model would react if it were to be 5 times bigger? material and weight wise, will it still work?

Good question. I think it would be really awesome to make this structure but GIANT. Please send me pictures if you make it!

如果它再大5倍,它会更重。我认为,如果你仍然使用薄木板,比如我用的1/8英寸的木头,那么用织物做接头就可以了。现在回想起来,我想我应该用一种更强力的胶水,比如木胶水,而不是粘性的胶水。但是如果你用更厚的木材,它会更重——不确定织物如何经久耐用。你可以试着用重型帆布,然后用钉书机或钉子之类的东西加固。

建立每个单元,另一个问题是如何the angles decided? what would happen if there was a 90 degree angle somewhere there? let's say between the bottom part of each unit and the left (the bigger slanted side), or between the top part and the left/right side?

这个不均匀的正方形有什么方程式吗?我该如何向一个人解释为什么这个结构/单元是这样建造的?

太棒了!:)你能解释一下你是怎么设计的吗?你所选软件中的工作流程(illustrator?融合?)。

Going down to the uni's fablab and lasercutting it the next few days! :)

如果你仔细观察构成这个结构的各个部分,你会发现所有的部分都是完全不规则的四边形,只是大小不同。

So, using Adobe Illustrator, I started out by experimenting with different irregular quadrilaterals with varying side lengths and angles. I knew that the right side of Quadrilateral 1 has to be the same length as the left side of Quad 2, and that the right side of Quad 2 has to be the same length as the left side of Quad 3, ... and so on. Because each quad is irregular, if we line them up side by side according to increasing size, then naturally they will form a spiral shape. I just kind of eyeballed it, then once I was satisfied with my quad, then I copied and pasted the shape over and over again, scaling it down each time so that the left side matched up with the previous quad's right side, until I decided that my 18 pieces made a large enough 2D spiral. Then I copied and pasted the whole thing again to get a total of 36 pieces, or 18 pairs of identical shapes, so that I can attach together 2 identical sides of the spiral for the curling motion interaction.

Looking back, I wish I made my quad with angles that are closer to 90 degrees so that the curling is less apparent when both sides of the spiral are closed together.

如果你真的做了这个冰壶雕塑,我很想看看你完成的作品的照片!:')

Dang! So cool! What a wonderful construction technique and use of canvas too!

太酷了。可惜我没有激光切割机

我想你也可以不用激光切割机来做这个,只是不能用木头做。你可以把模板打印在纸上,粘贴在纸板或泡沫芯上,然后用x-acto刀把它剪下来。
