摘要
文章在分析温度对于岩石的影响以及在温度场作用下岩石内应力分布情况的基础上,通过设计加热实验装置实现温度-应力耦合作用下盘形滚刀的破岩效果研究,其中加热装置设计、温度场对于岩石的影响为设计的重点。文章采用ABAQUS软件分析模拟了温度对于岩石的影响以及在温度场作用下岩石的内应力分布情况。结果表明,此实验装置的设计对于研究岩体力学属性的影响规律、提高破岩效率、增强地质适应性、延长滚刀使用寿命等方面具有重大意义。
Based on an analysis of impact of temperature on rocks and internal stress distribution of rock under temperature field, the rock breaking effect of disc cutters under temperature-stress coupling effect was studied by designing a heating test device. The heating device design and impact of temperature field on rock are the key points of design. The impact of temperature on rock and internal stress distribution of rock under temperature field were simulated by ABAQUS software. The design of experimental device is of great significance in study of influence on rock mechanical behavior, improvement of rock breaking efficiency, enhancement of geological adaptability and prolonging service life of cutter.
