geklemmter Stoss

English translation: impact on constrained body regions

German to English translations [PRO]
Tech/Engineering - Automation & Robotics / safety in human-robot collaboration
German term or phrase: geklemmter Stoss
The entire context is a method for preventing accidents in human-robot collaboration.

In vorteilhafter Auslegung können Stoßeffekte durch Einsatz geeigneter Prallelemente (Schaumstoffe, oder Ähnliches) nachgebildet und in der Folge kritische Bahnpunkte gepolstert und als Optimierungsempfehlung dokumentiert werden. Korrekturfunktionen für FREIER STOß auf GEKLEMMTER STOß (vgl. IFF-Studie, TS 15066) etc. können ebenfalls
berücksichtigt werden.

I am really clueless about the meaning of geklemmter Stoss.

Thanks in advance for any suggestions.

English translation:impact on constrained body regions
Explanation:
A NIST report quotes on page 3 an IFF study on robot impact forces, noting specifically "instantaneous impact of free and constrained body regions". The German report talks about "Stoßimpuls" and "Klemm-/Quetsch-Impuls" and variations of these terms. The concept is this: First, imagine you're standing face to face with a robot in a free area and get hit by the robot's fist onto your upper left arm. You just suffered a free impact as your arm and body can swing or fall backwards in response to the impact. Then imagine you're standing with your back against a wall and get hit the same way. Now you and your arm are held in place by the wall and your arm gets pinned against the wall by the fist - it is constrained and therefore gets clamped or "(ein)geklemmt", and it probably suffers some damage, a bruise or "Quetschung".
