本研究系以扭摆法量测电动轮椅之转动惯量。轮椅的惯性是控制的重要因素，是轮椅驾驶的关键问题。实验测试平台由底部圆形木板、上部金属板和四根绳索组成。使用具有已知惯性矩的材料，例如金属盘和圆柱体，来测试系统的准确性。实验中使用的EPW是Invacare G3 Torque SP Storm Series。该系统对轮椅的转动惯量进行了测量，测量结果为5. 2280 kg-m2，即使在物体为251 bs的情况下，系统误差也小于10%。与其它近似方法比较，结果一致。此外，该实验方法还可用于手动轮椅等不规则物体转动惯量的测量。
This study describe an experiment measuring the moment of inertia of an electric powered wheelchair (EPW) using a torsional pendulum method. Inertia of the wheelchair is an important factor for control, which is a key issue in wheelchair driving. The experimental test platform consisted of a bottom circular wood plate, an upper metal plate, and four ropes. Materials with known moments of inertia such as the metal disk and cylinder were used to test the accuracy of the system. The EPW used in the experiment was Invacare G3 Torque SP Storm Series. The measured result of the moment inertia of the wheelchair was 5.2280 kg-m2and the errors of the system are less than 10% even when the object is only 251bs. The results are consistent when compared with other approximate methods. In addition, the experimental method could be used to measure the moment of inertia of manual wheelchairs and other irregular objects.
