全苏铁路运输科学研究院乌拉尔分院研制成功д—50、д—50M、2д100型柴油机曲轴转速调速器试验台。现有的试验台在模拟转速变化时,其转动质量的惯性力矩要比曲轴及与其相接的机械装置(发电机电枢、连杆—活塞组)的惯性力矩小得多,这是因为试验台的工作条件不可能与柴油机上的工作条件达到完全一致。所研制的试验台利用液力增力器来模拟所需的惯性力矩。当轴箱的转动工作频率为 All-Su-Ural Branch of the Academy of Railway Transport Research successfully developed д-50, д-50M, 2д100 diesel engine crankshaft speed governor test bed. Existing test rigs have a much lower moment of inertia when compared to a crankshaft and its associated machinery (generator armature, link-piston set) at simulated speed changes because the test bed The working conditions can not be exactly the same with the working conditions on the diesel engine. The test rig developed uses a hydrodynamic booster to simulate the required moment of inertia. When the rotation of the axle box frequency of work
