Abstract

A generator bag for impact power measurement converts the impulse to an increase in hydraulic pressure which is measured electronically. A leather cover has a rubber lining which is filled with water. Under the influence of an external force (for example a punch from a boxer) the pressure in the bag increases and actuates a piezo transducer. The transducer converts the pressure increase to an electrical potential which is recorded, by means of a measuring amplifier and recording device. The electrical potential generated by the generator bag is directly proportional to the impact strength.

Description

B E S C H R E I B U N G DESCRIPTION

Dynamosack für Schlakraftmessung Mit Hilfe eines dynamographischen Sackes wird die Schlagkraft (Schlagimpuls) elektronisch gemessen.Dynamo bag for sleep strength measurement With the help of a dynamographic Sack, the impact force (impact pulse) is measured electronically.

In einer Lederhülle befindet sich eine Gummiblase, die mit Wasser gfüllt ist. Beim Auftreten einer äußeren Kraft (z.B.In a leather case there is a rubber bladder that is filled with water is filled. When an external force occurs (e.g.

Schlagkraft eines Boxaportler) erhöht sich der Wasserdruck im Sack, der mit einem piezoelektrischen (bzw. Druckaufnehmer mit Dehnungsmeßstreifen) Druckaufnehmer versehen ist.Punching power of a Boxaportler) the water pressure in the sack increases, the one with a piezoelectric (or pressure transducer with strain gauge) pressure transducer is provided.

Dieser Aufnehmer wandelt den Druckanstieg in eine elektrische Spannung um, die über einen entsprechenden Meßverstärker am Registriergerät aufgezeichnet werden kann.This transducer converts the pressure increase into an electrical voltage to that recorded via a corresponding measuring amplifier on the recorder can be.

Die beim Schlag gegen den Dynamo-Sack auftretenden elektrischen Spannungen sind dann direkt proportional zur Schlagkraft.The electrical voltages that occur when the dynamo sack is hit are then directly proportional to the impact force.
