基于Mathematica的塑料燃油箱试验数据非线性回归分析

Non-linear Regression Analysis on Experiment Data for Plastic Fuel Tank Based on Mathematica

介绍了运用Mathematica软件对乘用车塑料燃油箱的高度—容积试验数据进行非线性回归分析的方法,并用不同的误差评价方法比较了非线性回归分析结果的误差,找出了误差最小的方法。在某新型号乘用车塑料燃油箱的设计开发过程中,通过综合运用Mathematica软件的相关计算功能、图形功能,实现了试验数据的回归分析和对回归分析结果的误差评价。

The method of non-linear regression analysis for the passenger car fuel tank high-volume experiment data based on the Mathematica software was introduced, and the non-linear regression error was evaluated by different methods, and the minimum error method was indicated. In a fuel tank development process, the engineering calculation functions and the graphics functions of Mathematica software were applied to achieve the non-linear regression analysis and error evaluation.
