【摘要】 《爆破工程》课程是高校城市地下工程、矿山建设工程专业的核心课程，爆破实验教学是实践教学中必不可少的环节。由于爆破工程具有高危险性的特点，传统的爆破工程实验建设难度大，难以在室内进行，给教学带来了不便，因此越来越多的学校依托虚拟仿真平台进行爆破工程实验教学。本文根据爆破工程虚拟仿真的教学思路及需求搭建了爆破实验教学虚拟仿真教学平台：利用Unity3D作为虚拟仿真系统的开发工具，保证虚拟仿真系统具有可在不同平台运行的高兼容性；使用3DS Max建立模型，并用Maya进行细节渲染，提高了模型的真实感；通过云渲染技术解决了加载速度慢、动画不逼真等问题；并且为了更好地体现实际工程中爆破振动波的传播机理，利用ANSYS模拟爆破振动波在不同岩层中的传播，波场云图以快照的形式保存在虚拟仿真系统，开展爆破振动虚拟仿真实验。实践和应用效果显示，虚拟仿真实验平台可实现学生独立地、深度地参与到爆破工程的教学实验中，提高了学生的实验体验和实践创新能力。更多还原

【Abstract】 Blasting Engineering is a core course in urban underground engineering and mining engineering in universities, and teaching blasting experiments is an indispensable link in practical teaching.As explosive engineering has a characteristic of great danger, the traditional explosive engineering experiment construction is rugged enough to be carried out indoors, which inconveniences teaching.Therefore, more and more schools rely on virtual simulation platforms.According to the teaching idea and demand of explosive engineering virtual simulation, this paper builds a virtual simulation teaching platform for blasting experiment teaching.Unity3D,a development tool for virtual simulation systems, was utilized to ensure high compatibility when running on different platforms.Meanwhile, the 3DS Max and Maya were applied to build and improve a realistic model.Furthermore, problems like slow loading speed and non-realistic animation through the cloud rendering technology were solved.The software ANSYS was used to simulate the propagation mechanism of blasting vibration waves in different rock layers better to reflect the blasting vibration waves in practical engineering.Finally, the wave field cloud map was saved as a snapshot in the virtual simulation system, and virtual simulation experiments of blasting vibration were carried out.The practice and application results show that the virtual simulation experiment platform can enable students to participate in the experiments of explosive engineering independently and deeply and improve students′ experimental experience and practical innovation ability.更多还原
