摘　　要：在气动系统中,气流回路既是驱动源,又是承载压力、流量等信息素的载体。针对气动系统闭环控制需要依赖电子传感器和控制器,提出利用气流反射原理,研究并设计一种具备接近感应的新型气流接近感应装置,实现了反馈口压力随物体靠近而增大的接近感知。通过正交试验和ANSYS流道仿真,对感应装置进行了内部流道优化,设计了一种应用该感应装置的自反馈抓取气动夹持器。实验结果显示,夹持器在靠近被抓取物体时能自动感应并执行抓取操作,摆脱了对电器元器件的依赖。In pneumatic systems,the airflow circuit was both the driving source and the carrier of pressure,flow,and other information elements.The issue of relying on electronic sensors and controllers for closed-loop control of pneumatic systems was addressed.It proposed to use the principle of airflow reflection to study and design a new type of airflow proximity sensing device with proximity sensing.This device achieved proximity sensing where the feedback port pressure increased as the object approaches.The internal flow channel optimization design of the induction device was carried out through orthogonal experiments and ANSYS simulation.A self-feedback pneumatic gripper using the sensing device has been designed.Experimental results showed that the gripper can automatically sense and perform grasping operations when approaching the grasped object,freeing itself from dependence on electrical components.
