摘要
动力舱空气流场是坦克动力-传动与辅助系统匹配的重要研究内容,目前主要靠传统的经验设计方法.目前的测试手段有限,很难详细了解动力舱内空气流动的真实情况,给动力舱方案的优化设计带来一定困难.借助流体分析软件是解决该问题的重要途径,如何使仿真结果有较高的置信度是流体仿真分析中的一项关键技术.作者在研究中采用台架试验与虚拟仿真相结合的方法,为流体分析提供了一种有效手段.
The air flow in engine compartment is a major research project on matching the power-driven and auxiliary system in tank. At present the research of air flow mainly depends on traditional empirical design method. As the test condition is limited, it is very difficult to make a detailed acquaintance of the air flow in engine compartment, which results in a certain degree of difficulty to the engine compartment＇ s plan optimization design. Using fluid analysis software is an important way to solve forementioned problem, but how to make the simulation result with a high degree of confidence is a key technology. A meth- od is adopted in this paper by using bench test and virtual simulation, which provides an effective means for the fluid simulation analysis.
