摘要

摘要:
复合压电材料是学习压电理论的优秀载体，但是用于复合压电材料虚拟实验教学的仿真软件仍有待开发。基于此，开发一款基于多孔碳酸钡和聚偏二氟乙烯(BTO@PVDF)复合压电材料模型的虚拟仿真实验教学软件，帮助学生理解基础压电理论、探究复合材料的压电响应特点。该软件整合材料设计、制备、表征的完整流程，设计多项可调参数、多层次展示结果，使学生更灵活地去自主实现复合压电材料综合性虚拟仿真，完成基于复合压电材料的虚拟实验。该软件添加了视频讲解、互动问答、知识点提示等互动，提高教学趣味性的同时，可培养学生独立思考的能力。

Abstract:
Composite piezoelectric materials are excellent carriers for learning piezoelectric theory, but simulation software for virtual experimental teaching of composite piezoelectric materials still needs to be developed. A software based on barium titanium oxide@polyvinylidene difluoride (BTO@PVDF) virtual simulation experiment teaching software of composite piezoelectric materials is developed. Students can investigate the properties of composites' piezoelectric response and get an understanding of basic piezoelectric theory by using the software to simulate flexible piezoelectric materials using models of porous and composite materials. With the help of the software, which integrates the entire process of material design, preparation, and characterization, creates multiple adjustable parameters, and presents the results at different levels, students can more independently and with great flexibility realize a more realistic virtual simulation of composite piezoelectric materials. The software adds video explanations, interactive questions and answers, knowledge tips and other interactions to improve the liveliness of teaching and cultivate students’ ability to think independently.
