Abstract:
At the present time, the airtightness testing method of diving devices is comparatively backward, with complicated and inefficient operation of testing devices, which has failed to ensure the airtightness of each diving suit. Regarding the fundamental research and development of the diving suit airtightness testing device, this paper determined the control scheme with the clamping force servo control as the core, drew the 3D model of the clamping and sealing module of the airtightness testing device by means of Solidworks, while conducting ANSYS analysis for the primary force components. Secondly, the mathematical model of the pneumatic servo control system of the diving suit airtightness testing test device was established, while the servo control system of the diving suit airtightness testing test device was analyzed by means of Matlab. It was determined that the stability of the servo control system of this testing experiment device was excellent. Upon the pole configuration, the perfor- mance of the pneumatic servo system of the diving suit airtightness testing test device was significantly enhanced, in which the overshoot and stabilization time of the pneumatic servo control system of the diving suit airtightness testing test device were signif- icantly shortened following the introduction of PID control. Lastly, this paper completed the study of airtightness testing methods, determined the testing scheme of diving suit airtightness testing test device by applying the testing principle of direct pressure testing method, in addition to making the design of the control program of PLC in accordance with the whole testing process.
