摘要

以某重型试验设备为例,对其承载运动副进行优化设计,目的是建立重型设备静压支承流体力学模型及结构设计算法。首先,建立总体设计方案,确定结构形式、初始油膜厚度及供油方式;其次,建立流体平衡方程,并解算相关参数;再次,计算性能参数,与实际需求比对;最后,反复迭代,直至达到最优解。结论:采用恒流量式供油的多腔静压支承盘支承力及油膜刚度满足实用需求,效率较高。
        Taking a heavy test equipment as an example,the optimum design of the bearing pair is carried to establish the hydrostatic model and structural design algorithm for hydrostatic support of heavy equipment。First of all,the overall design scheme is established,and the structure form,initial oil film thickness and oil supply way are determined.Secondly,the fluid balance equation is established and relevant parameters are calculated.Thirdly,the performance parameters are calculated and compared with the actual requirements.Finally,repeated iteration until reaching the optimal solution.It is concluded that the supporting force and oil film stiffness of the multi-cavity hydrostatic support plate with constant flow oil supply meet the practical demand,and the efficiency is higher.
