压缩弹簧是一种开放式螺旋弹簧，用于抵抗轴向压缩力。
压缩弹簧是一种开放式螺旋弹簧，用于抵抗轴向施加的压缩力。它设计用于承受压缩载荷，因此随着载荷的施加，弹簧会变短。弹簧的主要功能是在压缩后恢复到原始长度，提供回弹力、吸收冲击、保持表面之间的力，或控制机械组件中的运动。 压缩弹簧基于胡克定律工作，即弹簧施加的力与其从平衡位置的位移成正比（F = -kx）。当压缩时，弹簧以材料弹性变形的形式储存势能。当载荷移除时，能量释放，使弹簧恢复到自由长度。

Compression springs are designed to operate with a compressive load and get shorter when loaded, while extension springs are designed to resist stretching and get longer when loaded. Compression springs typically have closed or ground ends, while extension springs have hooks or loops at the ends.
The spring rate (k) is calculated using the formula: k = (G × d⁴) / (8 × D³ × N), where G is the modulus of rigidity of the material, d is the wire diameter, D is the mean coil diameter, and N is the number of active coils.
Common failure modes include fatigue failure due to cyclic loading, corrosion (especially in harsh environments), over-compression beyond solid height, improper installation causing buckling, and material defects. Proper design considering working stress, fatigue life, and environmental factors can prevent most failures.
