چکش ضربه الکترونیکی دیجیتال

RD³ (دستگاه ردیابی سریع آسیب) یک ابزار بازرسی غیر مخرب کم هزینه و دستی است که می تواند برای شناسایی فضاهای خالی ، تخریب و لایه لایه سازی در ساختارهای مرکب استفاده شود. با ضربه چکش ، دیگر ضربه زدن با سکه در یک محیط پر سر و صدا برای نتایج مشکوک وجود ندارد. RD³ ، همچنین به عنوان چکش ضربه الکترونیکی دیجیتال شناخته می شود ، با یک قرائت عددی کمی و عینی که می تواند با لایه لایه شدن در ساختار ارتباط داشته باشد ، تبعیض زبانی ذهنی اپراتور را تکمیل می کند. این واحد متشکل از یک چکش سبک وزن حاوی شتاب سنج است که توسط کابل انعطاف پذیر به ماژول دستی متصل به اجزای منطق دیجیتال و نمایشگر کریستال مایع متصل می شود.

The RD³ (Rapid non destructive Device) is a hand held, low cost non destructive inspection instrument that can be used to detect voids, degradation, and delaminations in composite structures. With a Tap Hammer, no more tapping with a coin in a noisy environment for questionable results. The RD³, also known as the Electronic Digital Tap Hammer, supplements the subjective tonal discrimination of the operator with a quantitative, objective numeric readout that can be correlated to delaminations in the structure. The unit consists of a lightweight hammer containing an accelerometer, which is connected by flexible cable to a hand held module containing digital logic components and a liquid crystal display.

With its low cost, quantitative and recordable readout and ease of use, the RD³ will prove invaluable and indispensable to routine non destructive examinations.

In a controlled comparison against another bondtester now on the market, the RD³ produced similar results and actually showed slightly greater relative signal change (sensitivity) at 4, 6 and 7 plies. (Their bondtester uses a solenoid-driven impact head to produce a controlled amplitude impact.) The RD³ did not show as great a signal change as the solenoid tapper did at 2 plies, but sensitivity is not an issue at this level because the signal difference between bonded and disbonded plies is so large. In terms of actual data, the RD³ compares favorably with the other much more complex and costly device.
