1、特性線與剛度：彈簧剛度為常量時，其特性線為直線。對于彈簧特性線為直線的彈簧，其剛度也常稱為彈簧常量或彈性系數(shù)。彈簧剛度為變量時，其特性為曲線。彈簧的特性線可能是直線、凸（凹）曲線，或前述幾種特性線的組合（稱為組合型特性線），在設計非線性線彈簧時，有時需要考慮其靜變形。2、變形能：彈簧變形后儲存的能稱為彈簧的變形能。在設計緩沖或隔振彈簧時，變形能是彈簧在受載后所吸收和積蓄的能量。3、固有頻率：當彈簧承受振動載荷時，為了檢驗載荷對彈簧系統(tǒng)的影響，需計算彈簧系統(tǒng)的固有頻率。環(huán)形的發(fā)條彈簧是市場上減振緩沖能力非常的發(fā)條彈簧。西安高彈性彈簧生產(chǎn)廠商</p><p
