基于斯特林热机模型，提出了一种测量其系统转动惯量的新方法.该方法无需拆卸实验装置，只需在热机驱动飞轮系统正常运转过程中接入负载发电机，通过测量负载发电机的输出功率及接入负载后热机驱动飞轮系统进入匀速转动阶段的角速度与撤去热机驱动后飞轮系统匀减速转动阶段的角加速度，即可间接测量出该系统的转动惯量.将此方法的测量结果与另外一种传统转动惯量测量方法进行对比，实验结果的对比分析表明，该方法具有较高的有效性和准确性.这一测量方法为结构复杂或难以拆卸的实验装置的转动惯量测量提供了一种新的理论研究途径，为不同驱动力驱动的飞轮系统的转动惯量测量提供了新的思路和应用价值.

Based on the Stirling heat engine model, a new method for measuring the system moment of inertia is proposed. This method eliminates the need to disassemble experimental setups. By simply connecting a load generator to the running Stirling heat engine system, the moment of inertia can be indirectly determined through measurements of the load generators output power, along with angular acceleration and angular velocity during the deceleration phase after loading. Comparative experiments with the traditional moment of inertia measurement methods demonstrate that this approach exhibits high validity and accuracy. The proposed method provides new perspectives and research pathways for measuring the moment of inertia in structurally complex experimental systems or those difficult to disassemble. It provides new ideas and application value for measuring the moment of inertia of flywheel systems driven by different types of driving forces.
