Design of Laboratory Cycle Accelerated Test Spectrum for Blade of Aero-engine Compressor
Natural environment test is to use real natural environmental conditions to study the performance degradation process of equipment under the comprehensive influence of natural environmental factors.In order to quickly obtain test results,environmental factors are equivalent acted on the study object in the form of accelerated test spectrum through certain methods in the laboratory by increasing the magnitude of one or more environmental factors,so that its corrosion/aging behavior can be evaluated in a short time,and this is a commonly used test and evaluation method in engineering at present.Based on the measured data of environmental factors in the humid and hot marine atmospheric environment,the design method of laboratory cycle accelerated test for engine compressor blades is elaborated,and it is proposed that the laboratory cycle accelerated test should be designed from four dimensions of environmental analysis,environmental test spectrum,test cycle mode and environmental test quantity value,which can improve the correlation between laboratory environment and actual service environment,and improve the effectiveness of laboratory environmental tests.
