通常螺旋压缩弹簧应具有尽可能小的体积,又能产生必要的工程行程以及载荷能力。一般通过试验和反复计算,才能确定弹簧的最省料尺寸。这里介绍一个简单的方法,不需要多次反复计算就能一次定出弹簧的最佳尺寸。这个办法是将弹簧的体积方程式对弹簧常数求导数,并使它等于零。然后通过移行,把方程变为弹簧参数和弹簧常数的关系式。推导过程略。结果是:为使弹簧体积最小,弹簧用料最少,必须满足下面公式: Usually helical compression spring should have the smallest possible volume, but also produce the necessary engineering stroke and load capacity. Generally through the test and repeated calculations, to determine the spring of the most material size. Here’s a simple way to determine the best size for a spring without having to go through multiple iterations. This approach derives the spring’s volume equation from the derivative of the spring constant and sets it equal to zero. Then by shifting, the equation becomes the relation between spring parameters and spring constants. Derivation process omitted. The result is: In order to minimize the spring volume, the spring material at least, you must satisfy the following formula:
