摘　　要：随着计算科学的发展,数字模拟技术被广泛运用于教育领域。在大学物理实验教学中,通过软件模拟可以更加直观显示实验现象和模拟规律,得到实验上无法测量的物理量,从而拓展实验教学的广度和深度。本文利用COMSOL Multiphysics软件对落球法测定黏度实验进行模拟分析,研究了落球法测定黏度实验中的速度场、压力梯度、速度变化和受力图等实验现象。研究发现COMSOL软件对实验建模具有很高的精度,可以有效辅助实验教学和开发,让学生加深对于物理实验规律的认识,培养学生数字化运用能力,从而提升实验教学效果。With the development of computing science,digital simulation technology has been widely applied in the field of education.In university physics experiment teaching,software simulations can more intuitively display experimental phenomena and simulate laws,obtaining physical quantities that cannot be measured experimentally,thereby expanding the breadth and depth of experimental teaching.This paper uses COMSOL Multiphysics software to simulate and analyze the viscosity measurement experiment using the falling ball method.It studies phenomena such as the velocity field,pressure gradient,velocity changes,and force diagrams in the viscosity measurement experiment.The research found that COMSOL software provides high accuracy in experimental modeling,effectively assisting experimental teaching and development.This helps students deepen their understanding of the laws of physics experiments,cultivate their digital application skills,and ultimately enhance the effectiveness of experimental teaching.
