On the impact of the jerk on structural dynamics

In mechanics, the term jerk, which is usually defined as time derivative of acceleration, often used incorrectly to interpret shock loads. Unfortunately, it very difficult convince technicians with less insight into basic laws mechanics that their views are invalid, since jerky motions undoubtedly have certain effects on dynamics mechatronic systems. The fact is, however, according Newton magnitude force acting a body determined exclusively by acceleration itself and not its derivative. From Newton's law follows only trivial statement change proportional acceleration. jerk become apparent in structural-dynamic applications, such robotics or biomechanics. this presentation, discussed for simple mechanical model make fundamental phenomena component vibrations, related understandable. Quantitative relations between amplitude vibrations derived analytically.
