What is shock vibration
-->Impact vibration is an integral part of the object's interference, which refers to the mechanical vibration generated by an object when it is subjected to sudden external force. This vibration is widely present in industrial equipment, transportation tools, building structures and other fields, and has an important impact on equipment life and safety. This article will structure the definition, classification, impact and response measures of impact vibration based on popular topics across the network in the past 10 days.
---1. Definition and characteristics of impact vibration
Impact vibration is a transient vibration phenomenon, and its core features include:
| feature | describe | |
|---|---|---|
| Short time | Usually set at the millisecond level, much smaller than ordinary vibration | |
| High intensity | Acceleration can reach 10-possibilities 100 times that of ordinary vibration | |
| Bandwidth | Covering a wide range of low to high frequencies | |
