Abstract

Abstract

In order to provide experimental basis for anti-impact design of the supporting structure of large nuclear power equipment and ensure that its impact resistance meets the requirements of relevant specifications, it is necessary to select the scaling model of the large equipment and its supporting structure as the research object of impact resistance technology and carry out impact test on standard medium-sized impact machine. According to the π theorem, the impact resistance test of the scaling model of the supporting structure of the large equipment is theoretically analyzed, and three optional test conditions are obtained; By changing the acceleration value of the scaling model, the maximum stress strength at the root of the supporting structure of the model is consistent with that of the prototype, and the difficult problem of test conditions in the derivation of π theorem is solved. The analysis method established in this study can provide a reference for the scaling test of the impact machine of the supporting structure of large equipment.
