How to Calculate Impact Energy for an Industrial Shock Absorber
Use moving mass and impact velocity to estimate the kinetic energy that the absorber must handle per cycle.
直接回答
For a moving mass, the base impact energy is kinetic energy: E = 1/2 x m x v^2. If gravity or an external drive force continues acting during the stopping stroke, add or subtract that work before comparing the result with the absorber energy-per-cycle rating.

所需输入
公式逻辑
Kinetic energy
m is moving mass in kg and v is impact velocity in m/s. The result is the base energy to absorb per impact.
E = 1/2 x m x v^2单位: N m
External-force work
F is drive force in N and s is stopping stroke in m. Add this when the drive keeps pushing into the stop.
W = F x s单位: N m
计算步骤
- 1
Calculate base kinetic energy
Use moving mass and impact velocity to calculate the energy carried by the moving object.
- 2
Add drive or gravity work
Add pneumatic, motor, external-force or gravity work when those forces assist the impact.
- 3
Compare with catalog energy rating
Select a model whose energy-per-cycle capacity is above the calculated requirement with margin.
常见错误
- Treating weight and mass as the same unit.
- Using average speed instead of impact speed at the stop.
- Forgetting that velocity is squared, so a small speed increase can require a much larger absorber.
目录来源说明
- The full product catalog tables use energy per cycle (Nm/C) as a primary product rating across EK, EN, EI and ED families.
