Current Researches on Anti-noise Flow Distribution Systems Less Sensitive to Operational Conditions of Axial Piston Pump
摘要
降噪技术是轴向柱塞泵的研究重点，传统的基于配流盘过渡区阻尼槽和错配角等配流结构的降噪效果受轴向柱塞泵工作参数的影响非常大，因此对其结构参数的优化不能实现全工况范围的最佳降噪效果，新型低敏感度全工况降噪配流结构是新的研究方向。通过对国内外学者在该领域研究工作的整理归纳，分析各种被动式及主动式配流方案实现全工况范围内降噪的工作原理，把配流结构分为6种，并指出各自的优缺点。总结国内外减振降噪配流结构研究方法，包括全压力范围油液弹性模量模型、油液惯性项、多目标优化理论及减振降噪测试方法，分析全压力范围油液弹性模量模型，建立基于轴向柱塞泵噪声产生机理的轴向柱塞泵多目标优化函数。最后对基于轴向柱塞泵新型配流结构设计和优化的降噪技术发展趋势做出预测。
Abstract
Noise reduction is the key research content in axial piston pump. The noise reduction effect of the traditional flow distribution structures is highly sensitive to varying operational conditions, mainly including relief groove and valve plate timing during transition area of valve plate. So the optimization of these structures might lead to much high noise emission if the operational conditions change. The anti-noise flow distribution system less sensitive to operational conditions is the new research direction. By summarizing the researches in this field at home and aboard, the operating principles of all the flow distribution structures were classified into six types and analyzed, including both passive and active systems. The advantages and problems of each structure were also discussed. Comparing different mathematical models on flow distribution of axial piston pump, including the model of bulk modulus variation with pressure, the fluid inertia and multi-objective optimization theory. The model of bulk modulus variation with pressure was analyzed and the multi-objective optimization function based on noise emission theory of axial piston pump was built. Finally, the tendency of the researches on noise reduction methods based on design and optimization of new flow distribution structures was forecasted.关键词
