ISO 10846-5:2008规定了一种驱动点法，用于在规定的预载下确定弹性支架平移的低频传递刚度。该方法涉及实验室测量输入侧的振动和力，输出侧被阻断，称为“驱动点法”。测量输入位移（速度、加速度）和输入力产生的刚度即为动态驱动点刚度。只有在驱动点刚度和传递刚度相等的低频情况下，该方法才能用于确定动态传递刚度。该方法适用于带有平行法兰的测试元件。

ISO 10846-5:2008 specifies a driving point method for determining the low-frequency transfer stiffness for translations of resilient supports, under a specified preload. The method concerns the laboratory measurement of vibrations and forces on the input side with the output side blocked, and is called the “driving point method”.The stiffness resulting from measuring the input displacement (velocity, acceleration) and input force is the dynamic driving point stiffness. Only at low frequencies, where the driving point stiffness and the transfer stiffness are equal, can this method be used for determination of the dynamic transfer stiffness.The method is applicable to test elements with parallel flanges.
