乳化液泵机液耦合建模与仿真
|
摘要
随着液压传动与控制技术的不断发展,对乳化液泵的性能提出了更高的要求。为研究、设计和开发高性能的乳化液泵,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,变更参数或条件困难,有时甚至无法实现。近年来出现的虚拟样机技术,可对泵的传动系统、液力系统的运动特性和动力学特性进行较为精确的仿真研究。
本课题以RBW315/31.5型乳化液泵为研究对象,在CATIA三维设计软件建立的虚拟样机的基础上,主要应用多体系动力分析仿真软件ADAMS和液压系统仿真软件AMEsim,建立了乳化液泵传动系统和液力系统的虚拟仿真模型,并研究了两种软件和模型在进行联合仿真时的耦合接口问题。
通过建立虚拟仿真环境下的乳化液泵机液耦合模型,对该型乳化液泵的液力系统进行了仿真研究,研究了曲轴在不同转速情况下,液力系统中柱塞缸内压力、输出流量以及吸排液阀的运动特性。研究得出,曲轴转速直接影响吸、排液阀的启闭特性,进而会影响泵的容积效率;在提高曲轴转速减小泵结构尺寸的前提下,以吸、排液阀的滞后角最小,泵容积效率达到最大为目标,合理地选择了乳化液泵的曲轴速度。仿真研究方法和结果对于研究分析乳化液泵性能、提高新产品开发的质量具有一定的实际意义。
With the developing of fluid power transmission and control technology, an increasing demanding for capability of Emulsion pump is even higher. To research, design and empolder more high-powered Emulsion Pump, only through traditional design ways need more cycle and cost to trial-produce and test prototype, and can not change parameter of Emulsion pump freely, even some can not be realized. In recent years, The virtual prototyping technology appears, which can make accurate simulation research on the movement and the dynamics of the transmission system and hydraulic systems of pumps.
This paper has taken RBW315/31.5 emulsion pump as the study object. Based on the Virtual Prototyping Technology established by three dimensional design software CATIA, it has mainly applied multi-body system simulation software ADAMS and hydraulic system simulation software AMEsim for establishing emulsion pump drive system and hydraulic system of virtual simulation model, and studied the issue of coupling interface produced by two types of software and models when conducting joint simulation.
Through the establishment of virtual simulation environment, it has researched the simulation of this type of emulsion pump the hydraulic system, as well as the plunger-cylinder pressure, output flow and the movement features of suction and discharge liquid valve in the hydraulic system in different circumstances. According to the research, crank speed directly affects the hoist characteristics of suction and discharge liquid valve, and then impact on pump volumetric efficiency; Under the premise of improving the speed of crankshaft and reducing the size of pump, choose logically the emulsion pump speed of the crankshaft, with the purpose of the minimum angle lag of suction and discharge liquid valve and the maximum of pump volumetric efficiency. Simulation research methods and results have certain practical significance in researching performance of emulsion pump, and improving the quality of new products.
