EQUIVALENT STATIC LOADS FOR RANDOM VIBRATION …

this case, the equivalent static load may be as much as one order of magnitude more conservative than the true dynamic load in terms of the resulting stress levels. Load Specification Ideally, the dynamics engineer and the static stress engineer would mutually understand, agree upon, and document the following parameters for the given component. 1.

What Is the Difference Between Static and Dynamic Loads?

Mar 31, 2020· Static Load vs. Dynamic Load The main difference between a static and dynamic load lies in the forces produced by the weight of an object. When static, the load remains constant and doesn''t change over time. With a dynamic load, some outside factor causes the forces of the weight of the load to change. Some of the factors that can affect a load ...
