The Structural Of Antenna Special PTZ’s Design And Analysis

With the development of information age, information has become the mostimportant resources in the modern society. The information transmission channel has beenthe past simple change cable for radio transmission. Antenna as the radiation and receivingelectromagnetic wave device,Occupies an important position in the radio communicationsystem. Yagi antenna is better measured anisotropy with the effect of long-distancecommunications antenna types, if Matched with control elevation and PTZ device, can bemore arbitrary packet of electromagnetic wave information received in all directions. Withthe military as well as civilian demand stimulation Yagi antenna, Ancillary PTZ deviceneeds become more urgent. PTZ is the product in such context.The study of the subject YTA-02PTZ is one of the control antenna. This design ismainly a novel platform for Yagi-U antenna, Because the Yagi antenna size. PTZ structuraldesign, mechanical properties, dynamic performance requirement,more stringent.Thesis research purposes：This article will analyzes YTA-02PTZ type overallstructure design and characteristics of research as the main line,to seek PTZ best structuralparameters，make The structure and properties of pan in the design stage to reach the best.The research contents and methods:(1)The development status of the head researchat home and abroad. Learn the basic types of PTZ. According to the PTZ performance andparameter design requirements, determine the head of design and layout, completed choicePTZ key components calculation. parts modeling and overall head in3D software UG7.0completed the virtual assembly.(2)Using finite element analysis software ANSYS-workbench PTZ mathematicalmodel analysis and mechanical model, Completion of the corresponding dynamic analysisof wind load conditions statics analysis and free vibration. Get the maximum stress anddeformation of the head as well as head of the natural frequencies and modes, IdentifyPTZ design weaknesses, Improved structural design and stiffness greater increase.(3) PTZ prototype successfully developed a performance test of environmentalexperiments as well as shock and vibration test.Through the performance test to detecthead in the load performance case. Through Environment experiment to tests the functionproperly in the different work environment.Shock and vibration tests to identify low-levelfrequency of the vibration of the head, the design should try to avoid these low frequency,description PTZ the mechanical institutions can adapt to the severe vibration and shock.The results and conclusions of the research paper: The new head of research and design, the mechanical transmission system to meet the requirements in the field ofmodern mechanical. Its dynamic and static characteristics to achieve the conditionsrequired to design. Various structural design have reached the intended target. Thesisstrongly support the development of a prototype of the new PTZ,.
