Based On ANSYS PCB Vibration Analysis System Development

With the development of electronic device manufacturing technology, andextremely rapid replacement of electronic products faster and faster frequency in recentyears, there is no doubt of the importance of the printed circuit board electronicequipment, and the core of the new situation, means that the new design of the PCB(printed circuit board) frequency is more rapid, more and more of the compression ofthe design cycle, and PCB circuit design complexity is increasing, more and morefactors to be considered. A successful and complete PCB design often requires designersto do the following in a short period of time, designed to achieve a predeterminedcalculation function circuit structure, the PCB reliability testing, such as vibrationanalysis, thermal analysis, and analysis of electromagnetic shielding To complete allwork in a short period of time, designers need to team with various related fields ofprofessional and technical personnel to co-general team are often unable to do so. Tosolve this practical problem, for of PCB vibration analysis and its analytical proceduresdeveloped in-depth study, the main research results are as follows.(1) Extensive and in-depth study of the various types of commonly used ANSYSsecondary development environment, secondary development method to select the mostappropriate for the subject content.(2) Summary mature finite element vibration analysis experience, do in-depthresearch and a number of key technologies, summed up the most basic set of general-purpose finite element PCB vibration analysis process, and its developed secondaryfunctional development of the development of software programs.(3) Successfully developed after the equivalent of the solid model calculation ofthe parameters of the template can be automatically calculated, and the calculatedequivalent data is stored centrally, and the establishment of a database to facilitate theusers to directly call and use it to build mode.(4) The ultimate success of developed PCB vibration analysis system, a view to thefinal results from the modeling vibration analysis of simulation steps.Premise of this thesis summarizes existing mature PCB vibration simulation experience further vibration simulation analysis on the finite element method, especiallythe analysis of analytical methods in software to achieve certain exploratory study, thereare certain learn and continue to study the significance of.
