This cell uses a collaborative robot to bring each part to an NVH test station, capturing sound and vibration under standard conditions; the system auto-compares and judges pass-fail — objective, quantified, not by ear. The payoff is direct: subjective sampling becomes objective full inspection, throughput rises about thirty percent, every test logged automatically, so complaints and recalls are backed by data.

At a glance

The problem

Three pits of manual listening. It is subjective — different people and states judge differently. It is fatiguing — attention drops over a shift and defects slip through. And it leaves no data — a gut call gives nothing to show or trace when complaints arrive.

The solution

This cell uses a collaborative robot to bring each part to an NVH test station, capturing sound and vibration under standard conditions; the system auto-compares and judges pass-fail — objective, quantified, not by ear.

In detail

The robot keeps clamping position and test cycle identical for every part — the precondition for objective judgment: only identical conditions yield comparable data.

Sound-print and spectrum are analyzed in real time; abnormal noise, bearing defects and loose assembly — hard for the human ear — are cut cleanly by threshold, stable and reproducible.

The results

The payoff is direct: subjective sampling becomes objective full inspection, throughput rises about thirty percent, every test logged automatically, so complaints and recalls are backed by data.

Flexibility & changeover

Changeover is fast too: drag-to-teach plus test templates mean a new model is just a program and threshold change — no rebuilt rig.

8. From noise to vibration, a collaborative robot with NVH testing turns end-of-line inspection into an objective, full, traceable standard process. This is EVST — we make line automation real.

FAQ

What makes this different from manual operation? Three pits of manual listening. It is subjective — different people and states judge differently. It is fatiguing — attention drops over a shift and defects slip through. And it leaves no data — a gut call gives nothing to show or trace when complaints arrive.

What are the measurable results? The payoff is direct: subjective sampling becomes objective full inspection, throughput rises about thirty percent, every test logged automatically, so complaints and recalls are backed by data.

How hard is changeover to a new part or model? Changeover is fast too: drag-to-teach plus test templates mean a new model is just a program and threshold change — no rebuilt rig.
