Hello, I've an assembly of a few components, all of them except one (the snap fit one) being rigidly fastened together. The snap fit component is inserted into the assembly and held in place by virtue of its design intent. I've calculations that shows the pull out force required(static) to pull the snap fit component out of the assembly. Now this assembly is being exposed to two physical phenomenon, one is a harmonic vibaration at a particular "g" and the other one a shock load, a sine pulse of defined "g" value and time. Now is there any way of relating the pull out force to the "g" values in the two cases as above. The intent is to predict the "g" force that is required such that the component makes its way out of the assembly. Any help/leads will be appreciated, Many thanks

Thanks Jboggs, F=ma would make sense with the shock load. But I'm not really sure if the same could be applied to the sine sweep scenario. The components to which it is attached is also moving with the same acceleration and displacment(assuming there is no dynamic amplification at the snap). So there is no relative movement between the parts to slide the snap fit component out Maybe I'm missing something in here, please share your thoughts, Job |

"g" equals acceleration, right? How about the old:
F = ma Is that just too simple? |
