Abstract

The present day economic scenario and market conditions has necessitated the importance of Science, Technology, Engineering and Mathematics (STEM) education to be industry oriented and interdisciplinary. This requires a rigorous curriculum coupled with pro active engagement of student learners. The engineering industry has adopted modelling and simulation technique for many of the apparent benefits including less time to market and reduced product development costs. In such a state of affairs, STEM courses pertaining to modelling and simulation are quintessential. The presented paper explains about the pedagogical exercise carried over in the Vehicle Dynamics course conducted for the final year Automobile Engineering students. The students were introduced to Acausal modelling approach for two fundamental exercises—single degree of freedom system, quarter car model—conducted for the laboratory sessions of the Vehicle dynamics course. The acausal modelling approach was compared with causal modelling approach which had been the widely deployed modelling technique. Matlab Simulink software was utilized for causal modelling and the open source platform OpenModelica was utilized for acausal modelling. Simulink/Simscape library was also utilized for comparison. The modelling time has reduced by 20%–37.5% for single degree of freedom system and by 10%–60% for quarter car model in acausal modelling approach. Most of the students agreed in a survey about the ease and simplicity when using acausal modelling technique when compared with causal modelling technique.

在车辆动力学教学中应用开源因果建模软件

当今的经济形势和市场条件已经需要科学，技术，工程和数学（STEM）教育的重要性，以行业为导向和跨学科。这需要一个严格的课程加上学生学习者的积极参与。工程行业已经采用了建模和仿真技术，以获得许多明显的好处，包括缩短上市时间和降低产品开发成本。在这种情况下，与建模和仿真相关的STEM课程是必不可少的。本文介绍了在汽车工程专业最后一年的车辆动力学课程中所进行的教学练习。在车辆动力学实验课中，向学生介绍了单自由度系统和四分之一汽车模型两个基本练习的因果建模方法。将因果建模方法与因果建模方法进行了比较。利用Matlab Simulink软件进行因果建模，利用开源平台OpenModelica进行因果建模。还使用了Simulink/Simscape库进行比较。在随机建模方法中，单自由度系统的建模时间缩短了20% ~ 37.5%，四分之一汽车模型的建模时间缩短了10% ~ 60%。在一项调查中，大多数学生认为因果建模技术与因果建模技术相比更容易和简单。
