基于虚拟样机的斜柱塞泵仿真研究

摘要
柱塞泵是一种应用广泛、控制多样、结构复杂的液压动力元件。随着液压传动和控制技术的不断发展,柱塞泵将向着高压大排量的方向发展,其产品的开发速度及其可靠性日益成为最具挑战性的因素。为研究、设计和开发高性能的柱塞泵,单纯运用传统的设计方法需要进行样机的试制和各种性能试验,周期长、成本高、变更参数和条件比较困难。本文将虚拟样机技术运用到柱塞泵的设计开发过程中,可以对泵的液压系统和运动控制部分进行精确的仿真分析,提高柱塞泵的设计水平。
本文以A4VSG750型斜盘斜柱塞泵为研究对象,在UG三维设计软件建立的斜柱塞泵装配模型的基础上,联合液压系统仿真软件AMESim和多体系动力分析仿真软件ADAMS,通过两者之间的接口,建立了斜柱塞泵的机液一体化虚拟样机模型；在ANSYS中将泵的芯部运动部件柔性化,通过与ADAMS之间的数据交换,建立了泵的刚柔耦合动力学模型。
对泵的机液一体化虚拟样机模型进行仿真分析,研究了泵在不同工况时的出口流量脉动特性和柱塞腔的压力变化,找出其中的规律；同时分析了泵在不同工况时的柱塞运动情况和芯部零件的受力状况,为斜盘斜柱塞泵的设计提供参考。对泵的刚柔耦合模型进行仿真分析,得到泵轴和柱塞在不同工况时的应力和应变分布云图,既可分析柱塞和泵轴的强度可靠性,也为其结构改型和系统开发提供了理论基础。
Piston pump is a widely used, versatile, complex structure of the hydraulic power components. With the development of fluid power transmission and control techniques, the piston pump will be developed toward the direction of high pressure and large flow. It is increasingly becoming the most challenging factor of the product development speed and reliability. In order to research, design and develop high-performance piston pump, the way that only using traditional methods need processing of physical prototype and a variety of performance tests on the physical prototype. These take more time and cost. It is difficult to change parameters and conditions of the pump with the traditional design method. This paper will introduce virtual prototype technology into piston pump design and development area, it can get a precise simulation and analysis of hydraulic system and motion control part to improve the design level of piston pump.
The research object in this paper is A4VSG750 swash plate pump with oblique pistons. The oblique piston pump assembly model is established in the UG three-dimensional design software. Hydraulic system simulation software AMESim and multi-system dynamic analysis and simulation software ADAMS are combined together. The virtual prototype model of oblique piston pump with mechanical and fluid integration is established through the interface between the two softwares. The core moving parts of the pump are changed to be flexible ones, a rigid-flexible coupling dynamic model of the pump is established through a data exchange between ADAMS and ANSYS.
Having a simulation and analysis on the virtual prototype model of oblique piston pump with mechanical and fluid integration, export flow pulse characteristics of the pump and pressure changes in piston antrums can be studied, and its orderliness can be found out. The virtual prototype model can provide reference for the design of swash plate pump with oblique pistons by analyzing the movement and force on core parts at different operating conditions. Having a simulation and analysis on the rigid-flexible coupling dynamic model, the stress and strain of shaft and pistons at different operating conditions can be obtained. The results are used to analyze the strength of shaft and pistons, and can provide a theoretical basis for structure retrofit and system development of the pump.
