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.
Motion is present in almost all industrial automation systems. Stopping or changing the direction of that motion releases kinetic energy, which can cause shock and vibration to occur.
Vibration damping: What’s the difference between passive and active methods?
Unlike typical static or dynamic loads, forces due to vibrations are difficult to predict, model, and account for when designing motion control systems.
What are negative-stiffness vibration isolators?
Protecting sensitive equipment from harmful vibrations can be done with either passive or active isolation systems, with the choice often being made on price, simplicity, and the level of protection required.
Gas springs, also called gas dampers, tension springs, or gas-pressure springs depending on the setup and context, are compressed-air or oil cylinders that install in motion designs to damp forces and return kinematic linkages and more complicated assemblies to default positions.
