How to Check Energy per Hour for Shock Absorber Selection
Why the same absorber can pass single-impact energy but fail under high cycle frequency.
Direkte Antwort
Energy per hour is the calculated energy per cycle multiplied by the number of impacts per hour. The selected model must satisfy both energy per cycle and energy per hour ratings, because repeated impacts create heat and duty-cycle limits.

Energy per hour
E is absorbed energy per cycle. ETC is the hourly energy load that must stay within the catalog rating.
ETC = E x cyclesPerHourEinheit: N m/h
Berechnungsschritte
- 1
Calculate energy per cycle
Start with the total stopping energy required for one impact.
- 2
Multiply by cycle rate
Multiply by the expected number of impacts per hour under normal operation.
- 3
Check heat-duty capacity
Compare the result with the catalog energy-per-hour rating, then review high-frequency families when needed.
Typische Fehler
- Selecting only by maximum energy per impact.
- Using ideal cycle rate instead of maximum production cycle rate.
- Ignoring hot environments that reduce thermal margin.
Kataloghinweise
- The full product catalog tables list both maximum energy per cycle (ET) and energy per hour (ETC), which makes this an answerable calculation topic.
