Sizing Industrial Shock Absorbers for
Upward Propelled Mass
When a mass is rapidly propelled upward by an external force—such as pneumatic or hydraulic cylinders—it creates significant kinetic energy that must be carefully absorbed to protect equipment. At Shockbuffer, we specialize in industrial shock absorber selection and precise sizing of shock absorbers for upward-moving applications to ensure smooth deceleration and avoid damage at the end of travel. Our medium industrial shock absorbers are designed to manage these dynamic loads safely, reducing vibration, improving machine reliability, and extending the life of critical components. Choosing the right shock absorber for machinery is essential for efficient and safe operation.
Formulae
E1 = W · v · 0.5
F = 2 ( 0.78 · D · P )
E2 = (F - (W · g )) · S
E3 = E1 + E2
E4 = (E3 · c)
vD = v
We = (2 · E3) / vD

Example: Sizing Industrial Shock Absorbers for Upward Propelled Mass
W= 430 Kg
V = 1.2 m/s
D =0.10 m
p = 551000 Pa
s = 0.10 m
C = 100/hr.
E1 = 430 · (1.2) · 0.5 = 309 Nm
F = 2(.78 · 0.10 · 551000) = 8580 N
E2 = (8580 - 4218) · 0.1 = 436 Nm
E3 = 309 + 436 = 745 Nm
E4 = 745 · 100 = 74500 Nm/hr
vD = 1.2 m/s
We = (2 · 745) / 1.2 = 1241 kg

Applications of Industrial Shock Absorbers
Typical shock absorber applications in this category include:
-
Pneumatically propelled lifting tables that raise parts to the next workstation
-
Fast-acting vertical actuators in packaging or assembly machines
-
Upward moving pushers that elevate products onto conveyors
-
Indexing lifts that propel pallets or containers to higher levels
-
Test rigs where parts are moved upward quickly and must stop gently
-
Automated material handling systems with upward thrust movements
In all these cases, a medium industrial shock absorber must be carefully sized to absorb the kinetic energy from the upward motion, providing controlled stopping and protecting machinery from excessive force and wear.
