    Abstract: In a mechanical test system, a method of compensating for acceleration induced load error in a load sensor in a mechanical communication with a component comprises measuring an acceleration of the component to obtain an acceleration measurement. A load sensor measures a force applied by the mechanical test system to a test sample in substantially a same direction of the acceleration to obtain a force measurement. The force measurement is modified with a transfer function that includes at least one of a gain correction and a phase correction to compensate for an error value in the force measurement attributed to movement of at least the load sensor when the force is applied to the test sample.

    Abstract translation: 在机械测试系统中，在与部件的机械通信中补偿负载传感器中的加速度感应负载误差的方法包括测量部件的加速度以获得加速度测量。 负载传感器测量机械测试系统对加速度基本相同方向的测试样品施加的力，以获得力测量。 力测量用传递函数进行修改，该传递函数包括增益校正和相位校正中的至少一个，以补偿当力施加到测试样本时归因于至少负载传感器的移动的力测量中的误差值 。
