ABSTRACT
This paper mainly uses three factors and three levels orthogonal experiment method to analyze the static stress of the fixed standard nozzle. The standard nozzle is divided into three regions of the A?B?C, and two groups of large loads of 8000 N and 10000 N are used to make the standard nozzle core. According to the test results, the maximum stress and strain of the key parts of the nozzle Flowmeter with large load appear in the position R1 the arc of the standard nozzle core tangent to the plane entrance, and the minimum stress appears in the standard nozzle core arc The outlet plane of the quasi-nozzle forgings, the maximum displacement appears at the end of the standard nozzle core. From this we can see that the R1?R2 and tail end of the standard nozzle core need to pay more attention to the selection of casting materials and processing technology.
