Abaqus质量缩放及其结果准确性的评估
Abaqus Mass Scaling and Evaluation of the Accuracy of Its Results

Abaqus质量缩放的目的是为了减少或者节约计算时间。主要表现在，在显式动力学的求解过程中，实际中的一秒或者零点几秒就需要花费计算机更长的时间进行运算，无法满足实际工程或研究的需要。有时可以适当扩大研究对象的质量，来达到减少计算机运行计算的时间。通过简单例子来揭示质量缩放意义和对结果正确性进行评估。最后对质量缩放的范围和相关设置进行介绍。
The purpose of Abaqus mass scaling is to reduce or save calculation time. The main performance is that in the process of solving the explicit dynamics, it takes longer time for the computer to operate in one second or a few seconds in practice, which cannot meet the needs of actual engineering or research. Sometimes the quality of the research object can be appropriately expanded to reduce the time of computer operation and calculation. This paper presents the significance of quality scaling and evaluates the correctness of the results through simple examples. The range of mass scaling and related settings is also introduced.
