Welcome to this installment of MC² on vibration damping and shocks!
Vibration is mechanical oscillation (regular or otherwise) about some equilibrium — prone to becoming problematic in motor-driven motion designs where there’s looseness, backlash, windup, uneven effects from friction, machine-assembly imbalances, or shock loading. Noise is a manifestation of vibration that degrades the perceived quality of machines … and in many cases is an unacceptable byproduct of motion.
So as we explore in several MC² features, the ultimate goal for design engineers is to build and tune designs for minimal vibration (free or forced) and render unavoidable system vibration damped (dissipated) or isolated. That way, the machine can quickly settle back to equilibrium. We also explore a phenomenon related to that of vibration — that of shock. Check out the below for more.
