Hydraulic Force

The force produced on the rod side (1) of a double acting hydraulic piston - can be expressed as. F 1 = P 1 (π (d 2 2 - d 1 2) / 4) (1). where . F 1 = rod force (lb, N). d 1 = rod diameter (in, mm). d 2 = piston diameter (in, mm). P 1 = pressure in the cylinder on the rod side (psi, N/mm 2). 1 bar = 105 N/m 2 = 0.1 Nm/mm 2; The force produced on the opposite of rod side (2) - can be expressed as

INTRODUCTION TO IMPACT LOADING

parentheses is the dynamic amplification–the factor by which a load is amplified when suddenly imposed. Since the displacement and load are proportional the effective force carried by the beam during impact is the product of the dynamic amplification and the weight, W. Note that the dynamic amplification for V = 0 (Ek = 0 ) = 2: a load suddenly
