球员和场地的相互作用特点是人造草坪场地建生和维护所要考虑的重要因素，一种重要的相互作用我们叫做牵引力或者扭转力，也叫做传动阻力。当阻力对应旋转力太高时，对运动员来说压力就变大，当阻力太小时，运动员可能会滑倒。因为这个原因，FIFA和IRB都制定了场地牵引力系数的测试流程，这也是Deltec牵引力系数测试仪所要测试的内容。检测的自由落体模块重量是46公斤，在制定的高度坠落来检测牵引里系数。独特的人类学设计使得检测设备的测试方式简单。自由落体重量模块包含几个不同的重量块。测试仪器还包含一个三脚架和一个轴承来保证自由降落和牵引力的测试包含***少的摩擦。检测重量模块自由降落后，扭矩待定值的结果由***的扭矩扳钳来旋转测试表的角度来表现（***少45度）。
特点
坚固耐用；
自由落体模块可以分解成几块；
仪器可以分解，组装；
航空箱包装；
可选搬运组件可以在测试场地上灵活搬运测试仪
应用场地：足球，橄榄球
应用标准：EN15301，EN15330，FIFA06
Rotational Resistance Tester
The interaction between player and field is an important factor in the asses***ent of an artficial turf surface.One of these interacti*** 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 sport***an.When the resistance is too low,the result can be insufficient grip with the effect of the sports-man slipping.For thisreas*** the FIFA and IRB h***e 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 for example c***ists of several plates.The testing device c***ists of a tripod with bearings to ensure that the free fall and subsequent rotation are executed with as little friction as ter the fall the required torque is determined by using the supplied torque wrench to rotate the test foot over an angle of a minimum of 45 degrees.
