impact hammer मीनिंग इन हिंदी

There are several ways to do modal testing but impact hammer testing and shaker ( vibration tester ) testing are commonplace.
Shakers can have an advantage over the impact hammer as they can supply more energy to a structure over a longer period of time.
Impact hammer testing is ideal for small light weight structures; however as the size of the structure increases issues can occur due to a poor signal to noise ratio.
The impact hammer test is designed to replicate this; however, in reality a hammer strike cannot last for an infinitely small duration, but has a known contact time.
