| 摘 要： | 根据土工试验要求研制了"动静三轴试验仪",该仪器设备能够替代传统"静三轴试验仪"和"动三轴试验仪"完成给定的试验任务.伺服加载的实现方式是"动静三轴试验仪"研制的核心,在分析液压、气动和电气加载方式的优缺点后,采用液压伺服加载方式完成轴向力和位移的动态、静态加载.为解决液压伺服加载系统在动态加载时液压油压力波动和静态加载时效率低、发热量大的问题,提出采用蓄能器组和恒压变量泵的解决方案并设计了液压油源系统,借助数学建模和仿真的手段验证了所提方案的正确性.

| Abstract: | According to the soil test requirements,a new dynamic & static triaxial apparatus is developed. This apparatus can replace the traditional dynamic triaxial apparatus and static triaxial apparatus to accomplish the testing task perfectly. The implementation of the servo loading is the key of dynamic & static triaxial apparatus. The electro-hydraulic servo loading system is adopted to accomplish the dynamic & static loading of the force and displacement after comparing the advantages and the disadvantages of ... |
