Engineering guide

Use the result with the right context.

Calculate shock absorber sizing calculator for a pneumatic application and compare the result with supplier data.

Calculation workflow

  1. Enter Effective moving mass, Impact velocity, Cylinder drive force and replace every default with application data.

  2. Run the calculation while keeping pressure, temperature, geometry, and reference states consistent.

  3. Interpret Required energy capacity, Load kinetic energy, Drive-force energy against the supplier datasheet, machine risk, and an appropriate design margin.

Assumptions and limits

  • The relationship is a first-pass rigid-body or elastic-member estimate; guides, joints, seals, and structural compliance can change the installed result.

  • Use pressure available at the actuator and verify mounting, cushioning, duty, speed, and catalog load limits.

FAQ

Common review questions.

01Tool noteWhat does the Shock Absorber Sizing Calculator calculate?

Estimate energy capacity per cycle and hourly heat dissipation for an external shock absorber stopping a pneumatically driven load. It returns Required energy capacity, Load kinetic energy, Drive-force energy, Average hourly dissipation so the primary answer and its supporting checks stay together.

02Tool noteCan I use the result as a final component selection?

Use it for preliminary engineering and RFQ comparison. Final selection must include supplier ratings, installation losses, transient conditions, applicable standards, machine risk, and validation testing.

03Tool noteWhy can a supplier calculation differ?

Supplier tools may use proprietary test curves, correction factors, rounding, leakage allowances, or reference conditions. Match those conditions and replace the defaults before comparing results.

04Tool noteWhat should I verify after using the Shock Absorber Sizing Calculator?

Check the entered units and reference conditions, then compare the calculated outputs with manufacturer ratings, application safety margins, transient loads, installation losses, and measured machine performance.
