摘　　要：为研究非血管支架的疲劳性能,该文依据非血管腔体生理运动规律,将其所产生的周期性循环载荷等效为波动载荷。通过设计基于PLC控制的液压加载模块和移位模块,对支架施加波动载荷,模拟支架在人体内的物理环境。试验测试结果表明,该装置可以实现多种类型非血管支架的疲劳性能测试,具有较好的通用性和可操作性。In order to study the fatigue performance of the non-vascular stent,the periodic cyclic load generated by the non-vascular lumen is equivalent to the fluctuating load according to the physiological motion law of the non-vascular lumen.A hydraulic loading device module and the shifting device module controlled by PLC are designed to apply the fluctuating load to the stent and to simulate the real physical environment of the non-vascular stent in the human body.The test results show that the device has good versatility and operability,and can realize the fatigue performance test of various types of non-vascular stents.
