摘　　要：针对定量式扇形静压油垫承载力计算未考虑离心力因素的影响,且传统计算方法缺乏试验验证的问题,首先推导得到考虑离心力的扇形静压支承油垫承载力模型,而后建立了转台的整体动力学模型,设计了液体静压转台试验方案,并进行了试验研究。通过理论计算值与试验值的对比分析表明,两者变化趋势基本一致,误差范围在比较合理的范围内,验证了考虑离心力的扇形油垫承载力计算模型和整体动力学方程的可行性。本文所建的模型及分析结论可以为实际生产及转台的服役性能提供理论支持。The quantitative sector fan-shaped oil pad bearing capacxty calculation aoes not take into account the effect of centrifugal force, and the traditional calculation method lacks experimental verification. To solve this problem, first, the bearing capacity model of the fan-shaped static bearing oil pad is derived, in which the centrifugal force is considered. Then the overall dynamic model of the turntable is established. The hydrostatic turntable experiment scheme is designed, and experiments are carried out. The experiment results are basically in agreement with theoretical calculation results that the error is within reasonable range, which verifies the feasibility of the model and the overall kinetic equation for the calculation of the bearing capacity of the fan-shaped oil pad considering of the centrifugal force. The model and the analysis conclusion of this work may provide theoretical support for practical production and the service performance of the turntable.
