Required energy absorption of a shock absorber — From operating conditions
Required energy absorption of a shock absorber struck by a workpiece carried on a belt conveyor. The belt keeps running as the workpiece slows, so friction acts in the direction of travel and the energy to be absorbed increases accordingly.
Input
Workpiece mass
Workpiece speed just before impact
Coefficient of friction
Acceleration due to gravity
Distance travelled from impact to stop
Result
Energy to absorb
