摘　　要：为实现对空间环境等离子体参数的测量,依据某航天任务要求,设计并制作了一种朗缪尔探针及其可展机构。该朗缪尔探针主要由传感器、电路盒和可展机构组成,具有锁紧模式和展开模式2种工作状态;可展机构由旋转部分和伸展部分组成,利用扭转弹簧和压缩弹簧进行驱动。为提高机构的尺寸稳定性,制作过程对各个筒体进行了时效和高低温定型处理,球形传感器表面采用金镀层以保证耐蚀性和导电性。通过在地面环境下的测试,验证了朗缪尔探针的可行性和正确性,对可展机构的研究具有实际意义。In order to achieve the measurement of plasma parameters in the space environment,this paper designs and manufactures a Langmuir probe and its deployable mechanism based on the requirements of a certain aerospace mission.The Langmuir probe is mainly composed of sensors,circuit boxes,and deployable mechanisms,and has two working states:locking mode and unfolding mode;the deployable mechanism consists of a rotating part and an extending part,driven by torsion springs and compression springs.To improve the dimensional stability of the mechanism,the manufacturing process has carried out aging and high/low temperature shaping treatment on each cylinder.The surface of the spherical sensor is coated with gold to ensure corrosion resistance and conductivity.The feasibility and accuracy of the designed Langmuir probe have been verified through testing in ground environments,which has important practical significance for the study of deployable mechanisms.
