style="text-indent:25px">為了避免振蕩，必須選擇彈簧固有振動(dòng)頻率以避免與作用在彈簧上的所有起振源振動(dòng)形成共振。另外，彈簧的固有振動(dòng)頻率由下式得出。在彈簧的設(shè)計(jì)計(jì)算中，也必須考慮下述事項(xiàng)。（1）彈簧指數(shù) 彈簧指數(shù)減小會(huì)導(dǎo)致局部應(yīng)力過(guò)大。另外，彈簧指數(shù)較大或較小時(shí)，加工性也成問(wèn)題。因此，熱軋成形時(shí)，彈簧指數(shù)可在4～15的范圍內(nèi)選擇。冷軋成形時(shí)，彈簧指數(shù)可在4～22的范圍內(nèi)選擇。（2）縱橫比為了確保有效圈數(shù)，壓縮彈簧的縱橫比(自由高度與螺旋平均直徑之比)可設(shè)定為0.8以上，另外，在考慮到端部磨平圈的情況下，一般可在0.8～4的范圍內(nèi)選擇。（3）有效圈數(shù) 如果有效圈數(shù)為3以下，彈簧特性則會(huì)變得不穩(wěn)定，因此應(yīng)將彈簧指數(shù)設(shè)定為3以上。（4）節(jié)距節(jié)距超過(guò)0.5D時(shí)，由于螺旋直徑通常會(huì)隨著撓曲量(負(fù)載)的增加而發(fā)生變化，需要對(duì)利用基本公式求出的撓曲量與扭轉(zhuǎn)應(yīng)力進(jìn)行修正，因此應(yīng)將節(jié)距設(shè)定為0.5D以下。一般說(shuō)來(lái)，節(jié)距利用下述簡(jiǎn)算式進(jìn)行推算。</p><p
