Impulse excitation technique
Impulse excitation technique is a way to figure out how stiff or how elastic an object is. It's like trying to learn how bouncy a ball is. When you throw a ball, it bounces back to your hand. The way it bounces tells you something about how much energy it can handle or how much it can move.
For impulse excitation technique, we use something like a small hammer, which is used to give a swift knock on the object. A soundwave is created and travels through the object, bouncing back and forth. A special instrument then measures how long it takes for the sound to travel through the object and how strong it is.
This tells us about how much energy the object can handle and how it moves. If it takes a long time for the sound wave to travel through the object, it means that the object is stiff, like a rock. If the sound wave goes through fast, the object is elastic, like a rubber ball.
Impulse excitation technique helps us to find out about the properties of materials like metal or concrete, which could be used for building structures like bridges, buildings, and airplanes. It helps us make sure that these objects will be strong and stable enough to last a long time without breaking down.
