人造草坪牽引力系數(shù)測(cè)試儀

球員和場(chǎng)地的相互作用特點(diǎn)是人造草坪場(chǎng)地建生和維護(hù)所要考慮的重要因素，一種重要的相互作用我們叫做牽引力或者扭轉(zhuǎn)力，也叫做傳動(dòng)阻力。當(dāng)阻力對(duì)應(yīng)旋轉(zhuǎn)力太高時(shí)，對(duì)運(yùn)動(dòng)員來(lái)說(shuō)壓力就變大，當(dāng)阻力太小時(shí)，運(yùn)動(dòng)員可能會(huì)滑倒。因?yàn)檫@個(gè)原因，FIFA和IRB都制定了場(chǎng)地牽引力系數(shù)的測(cè)試流程，這也是Deltec牽引力系數(shù)測(cè)試儀所要測(cè)試的內(nèi)容。檢測(cè)的自由落體模塊重量是46公斤，在制定的高度墜落來(lái)檢測(cè)牽引里系數(shù)。獨(dú)特的人類(lèi)學(xué)設(shè)計(jì)使得檢測(cè)設(shè)備的測(cè)試方式簡(jiǎn)單。自由落體重量模塊包含幾個(gè)不同的重量塊。測(cè)試儀器還包含一個(gè)三腳架和一個(gè)軸承來(lái)保證自由降落和牽引力的測(cè)試包含最少的摩擦。檢測(cè)重量模塊自由降落后，扭矩待定值的結(jié)果由特制的扭矩扳鉗來(lái)旋轉(zhuǎn)測(cè)試表的角度來(lái)表現(xiàn)（最少45度）。

Rotational Resistance Tester

The interaction between player and field is an important factor in the assessment of an artficial turf surface.One of these interactions is the torsion or traction,also known as the rotational resistance.When the resistance against rotation is too high,too much stress may be placed on the joints of the sportsman.When the resistance is too low,the result can be insufficient grip with the effect of the sports-man slipping.For thisreasons the FIFA and IRB have made a testing procedure which can be performed with the Deltec Rotational Resistance Tester.The test foot must be loaded with weights till it reaches 46kg and must fall from a predetermined height before determining the resistance against rotation.The Deltec Rotational Resistance Tester performs the measurements in a simple manner.During the development,special attention was given to ergonomic characteristics of the device.The weight
