摘要/Abstract

摘要：

为了揭示主要几何参数对水压马达止推环功率损失的影响规律,按照L16(45)正交表,选取了腰形槽个数、腰形槽宽度、阻尼管长度等5个因素,每个因素取4个水平，设计出16种方案。采用数值模拟的方法对所设计的方案进行正交试验,得到了16种设计方案的功率损失值,并通过极差分析找到了各几何参数对止推环功率损失影响的主次顺序,提出了止推环参数的最优设计方案。根据优选结果并结合数值模拟对水压马达止推环的止推特性进行了分析,得到了适合于水压传动的剩余压紧力系数。

Abstract:

In order to find out the effects of geometrical parameters on power loss of thrust collar in water hydraulic motor, an L16(45) orthogonal experiment was designed with five factors and four levels including kidney form groove numbers, kidney form groove width, damper length, etc. 16 schemes were designed totally. Numerical simulation was adopted to do orthogonal test, 16 groups of the design scheme for power loss were obtained. The primary and secondary sequence of the geometric parameters affect power loss of thrust collar was acquired by the method of range analysis. A best design scheme for thrust collar was proposed. According to the optimal results and numerical simulation,thrust characteristics of thrust collar in water hydraulic motor were analyzed. And a suitable residual pressing force coefficient for water hydraulic transmission was acquired.

Key words: water hydraulic motor, thrust collar, numerical simulation, orthogonal test, parameter optimization
