摘　　要：发动机核心机单元体在进行动平衡测试时,为保证测量精度,需要考虑驱动端的不对中对测量精度造成的影响。本文对不对中进行受力分析,再结合ANSYS有限元分析软件建立核心机单元体及平衡机摆架的动力学模型,通过计算及仿真发现,不对中有可能会影响到动平衡的测量精度。对本试验研究的核心机单元体的动平衡测试而言,在现有的驱动端不对中要求下对动平衡测量精度的影响可以忽略。In order to ensure the measurement accuracy of the core engine during the dynamic balance test,it is necessary to consider the effect of drive side misalignment on the measurement accuracy.In this paper,the force analysis of misalignment is carried out,and the dynamic model of the core engine unit and the balancing machine pendulum frame is established by ANSYS.Through calculation and simulation,it is found that the drive side misalignment may affect the accuracy of dynamic balance test.For the dynamic balance test of the core engine unit studied in the paper,the effect of the drive side misalignment on the measurement accuracy of dynamic balance test can be ignored.
