The goal of the fluidity test is to evaluate the ability of the melt to fill the cavity of the mold, which is one of the factors affecting the final quality of the castings. It is a technological test that is basically not standardized, therefore it is realized in different forms, for example using “horizontal” and “vertical” molds. The “horizontal” mold makes it easier to fulfill the condition of repeatability, therefore it was used to calculate the capability of the test by the Measurement Systems Analysis (MSA) method. The results of the tests in both molds were used to calculate regression equations that allow the fluidity to be determined with strong reliability based on variables such as melt temperature, casting speed, and mold temperature. In addition, the effects of input data variability (uncertainty) on the resulting fluidity value were analyzed using regression equations and the Monte Carlo simulation. The contribution of the article is the analysis of the capability of the measurement process of the fluidity and a prediction of the results of its tests using the Monte Carlo simulation method.

铝硅合金流动性试验仿真模型

流动性测试的目的是评价熔体填充模具型腔的能力，这是影响铸件最终质量的因素之一。它是一种基本上不标准化的技术测试，因此它以不同的形式实现，例如使用“水平”和“垂直”模具。 “水平”模具更容易满足重复性条件，因此采用测量系统分析（MSA）方法来计算测试能力。两个模具中的测试结果用于计算回归方程，从而可以根据熔体温度、铸造速度和模具温度等变量可靠地确定流动性。此外，使用回归方程和蒙特卡罗模拟分析了输入数据变异性（不确定性）对所得流动性值的影响。本文的贡献是使用蒙特卡罗模拟方法分析了流动性测量过程的能力并预测了其测试结果。
