HALF-SINE AND HAVERSINE IMPACT SHOCK PULSE |
 |
|
Peak Acceleration
m.s-2 OR
g.
(values must not exceed: 200,000 m.s-2 (or 20,000g) )
|
Pulse Duration
millisecs.
(values must not exceed 5000 milliseconds) |
Coefficient of Restitution
1 = elastic collision (perfect rebound) 0 = inelastic collision (no rebound) |
For a free-fall half-sine or haversine drop test, the program computes:
- initial impact velocity - velocity change during impact
- free-fall drop height and - surface deformation (#)
(#) For zero rebound, surface deformation is computed.
For full rebound, effective spring deflection is computed.
For intermediate values a weighted average is taken.
Values are given to 2 decimal places for convenience only -
they do not signify accuracy of real world test values.
