Shock compression target numbers
  • Shock compression target numbers - Woods thru SX                                 vdb / excel / shc_target_numbers.xls
  • shc target nu series is obsolete with c-zets, but we will leave up for now.      
    • Woods at lower end.  MX around aver.  SX at upper end.
    • Pressure testing breaks down the forces into: comp force, cadj force, drag force and gas force.
    • HOWEVER, for shc target nu series, we only list oall comp force.  The cadj force is based on keeping P.r about 10% above P.ca at 50ips (via Susanto excel).      
    • 10.2 range:        2.7    /     3.0      /   3.5
    • 50.10 range:      3.3   /      3.6     /    3.9
                     less prog   / mid prog /  more prog
                       more ls  /   mid ls   /  less ls                                              
    8-27-17, we revised the shc target nu series making it slightly stiffer at 20-40ips.
    4-20-18, this shc target nu series is dated compared to r-zeta and c-zeta.  The target numbers will actually change with
                   lev ratio and spring rate. AND we are finding a different curve than those shown below.
