How to Size a Shock Absorber for Horizontal Linear Motion
Calculate a horizontal moving mass by kinetic energy, then add drive force if the actuator continues pushing.
直接回答
For horizontal free motion, start with kinetic energy from mass and impact velocity. If a cylinder, motor or external force continues pushing during the stopping stroke, add F x s to the energy requirement and check energy per cycle, energy per hour, stroke and force ratings.

所需输入
公式逻辑
Horizontal kinetic energy
Base energy for a horizontal load approaching the stop.
E = 1/2 x m x v^2单位: N m
Drive work during stop
Add when the actuator continues pushing while the absorber compresses.
W = F x s单位: N m
计算步骤
- 1
Start with free-motion energy
Calculate energy from mass and impact velocity.
- 2
Add actuator contribution
For cylinder, motor or force-driven axes, add drive work across the stroke.
- 3
Filter suitable models
Use stroke, energy per cycle, energy per hour and maximum impact force to shortlist models.
常见错误
- Ignoring drive force on powered axes.
- Using conveyor speed before acceleration instead of actual speed at impact.
- Ignoring side load when the stop is not aligned with the motion axis.
目录来源说明
- The full product catalog application data asks for horizontal or vertical motion, weight, impact velocity, thrust force if needed and cycles per hour.
