Hi, Gurus,
In EIRENE test, a standard of EU train on handheld, "The Operational radio shall be capable of withstanding the following shocks: - semi-sinusoidal shocks of up to 5g for up to 100ms under normal conditions."
Now since the test lab can NOT reach 100ms, only can reach to 30ms, so if can say, "17g/30ms shock force is greater than 5g/100ms?"
I just want to get the same force as 5g/100ms, not very much gretaer.
I think the force is relate to momentum, i.e. MV. Since M doesn't change, the force is relate to velocity(V). Then the shock force is proportinal to V, which is a*t, so for 5g*100ms, we need 17g*30ms. I don't know if it is right for such calculation.
Pls comment.
Best,
Tony Liu
