Title
(EN) LOAD MEASURING DEVICE AND LOAD MEASURING METHOD
(FR) DISPOSITIF DE MESURE DE CHARGE ET PROCÉDÉ DE MESURE DE CHARGE
(JA) 荷重測定装置及び方法
Abstract
(EN)
Provided are: a load measuring device which, when the load upon elongation of an elastic member is measured, can prevent a measurement error due to an initial load in a state in which a pair of clamping parts clamp the elastic member; and a load measuring method. According to the present invention, a tensile load is measured by: making an initial load measured at an initial location zero by allowing a pair of clamping parts 5, 7 to relatively approach or be spaced apart from an initial location at which an attachment spring S is clamped; and relatively spacing the pair of clamping parts 5, 7 apart from each other while taking a location at which the initial load is made zero as a start location.

L'invention concerne : un dispositif de mesure de charge qui, lorsque la charge à l'allongement d'un élément élastique est mesurée, peut empêcher une erreur de mesure due à une charge initiale dans un état dans lequel une paire de parties de serrage serrent l'élément élastique ; et un procédé de mesure de charge. Selon la présente invention, une charge de traction est mesurée en : créant une charge initiale mesurée à un emplacement initial zéro en faisant approcher ou s'éloigner relativement une paire de parties de serrage 5, 7 d'un emplacement initial auquel un ressort de fixation S est serré ; et éloigner relativement les parties de la paire de parties de serrage 5, 7 l'une de l'autre en prenant un emplacement auquel la charge initiale est rendue nulle en tant qu'emplacement de départ.

弾性部材の引張り時の荷重を測定する場合に、一対の把持部に弾性部材を把持し た状態での初期荷重による測定誤差を防止することが可能な荷重測定装置及び方法を提供する。 一対の把持部5,7に密着ばねSを把持した初期位置に対して相対的に近接又は離間させることで、初期位置で測定された初期荷重をゼロにし、初期荷重がゼロになった位置を開始位置として一対の把持部5,7に相対的な離間を行わせ引張り時の荷重を測定させる。
