近来,液压机制造业优先发展泵直接传动系统。而进一步完善这类传动主要在于寻求提高它的经济性的方法,在这方面泵—飞轮传动具有显著的作用。需要确定泵—飞轮传功的主要参数是电机的安装功率和飞轮质量惯性距。电机功率可以根据液压机工艺循环的平均功率进行选择。但这种方法,正如文献[2]中所指出的,只有当 Recently, the hydraulic machine manufacturing industry to give priority to the development of pump direct drive system. The further refinement of this type of drive lies primarily in the search for ways to increase its economy, in which pump-flywheel transmission has a significant role. Need to determine the main parameters of the pump - flywheel power transfer is the installation of the motor power and flywheel mass inertia. The motor power can be selected according to the average power of the hydraulic machine technology cycle. However, this method, as pointed out in [2], is only valid when
