Abstract Atmospheric ping suit (Atmospheric Diving Suits, referred to as ADS) is a kind ofmanned underwater equipment of human form. The standard atmospheric pressure can beheld in the harness.An operator can work without underwater regard to decompressionproblems,improving the ability to ping repeatedly and extending the time of operatingunderwater.With the depletion of land resources, development of marine resources hasincreasingly received great attach of various countries.As a convenient and flexibleunderwater operation equipment,Atmospheric Diving Suits has become the importantequipment for human exploration and exploitation of ocean.Domestic technology ofAtmospheric Diving Suits compared to other countries, is not mature enough. There is abig gap in the pe depth of operation and flexible degree. In order to improve theperformance of Atmospheric Diving Suits,its elbow as an important component, thestructure of the elbow directly determines the working capacity, efficiency and safety.This paper focuses on the current the problems faced by the Atmospheric DivingSuits,optimizing the structure and properties of the original elbow,and completing thestructure design of a new type of elbow joint. The first step is to analyze the defect of theoriginal elbow joint.The rotation torque in the test is too large,and the elbow do not rotateflexibly and tightly enough. The next step is to analyze its shortcomings in structure, suchas the single row arrangement of the balls in the bearing,and the structure of edge. Thenanalyze the causes of the defects, because the original bearing moves and the body tiltsand offsets which makes the edge withstand uneven stress, creating a gap.Next,start thestructure design and optimization of the elbow joint.In order to achieve normal underwateroperation of pers,ensure the safety of pers and improve work efficiency,elbow shouldhave good flexibility and tightness.After the design,the three-dimensional modeling shouldbe made on the basis of design. Finally, stress intensity of the elbow should be calculatedand checked to ensure the system rationality.It should be realizing a reduction in a rotatingtorque of elbow joint, and ensure the stability of the bearing and the edge sealing.
