Circular Coil Spring Fatigue Test Method Research

Spring fatigue testing machine for spring loading of equipment, Itpassed in a laboratory environment to test pieces were imposed to cyclicalstress testing to test the fatigue life of purpose Experimental resultsshow that the reliability of the experimental data, for its successfuluse of guarantee Targeting the papers to the high-speed large displacementspring tension and compression testing machine fatigue as the main study.mainly for the following several aspects:1. The basic theory and the spring mechanism of fatigueExtensive collection of information, reading literature, summarizedthe spring fatigue mechanism, Spring fatigue affecting factors, thefatigue curve, spring fatigue estimates, Spring fatigue life reliabilitymodel.2. Spring fatigue test methods and fatigue curvesBased on national standards on the spring fatigue test method and theactual code, and experimental data processing to map out the fatiguecurve.3. Spring fatigue test machines from domestic demand analysisFatigue from the current domestic ownership of a testing machine totest the ability to expand coverage and the need for the project, theanalysis of fatigue test.4. Spring fatigue test of the general structuralCollation and analysis of comprehensive consideration of the existingexperimental spring of structure, type, parameters, etc. and it is concluded that the topic for both user-friendly and scientific structure,It was also found that other types of products deficiencies Departmentto be improved.5. Experimental control system software developmentSoftware development, we should draw on the test machine currentlyavailable on the advanced experiences and learning from each other,developing some new functions, Computer use as much as possible to achievethe simple man-machine communication, and through the acquisition sensoroutput, more intuitive to see the dynamics of spring.
