HYDRAULIC-PRESSURE PULSES WITH STRUCTURAL FLEXIBILITY: TEST AND ANALYSIS (LWBR Development Program)

摘要

Pressure pulse tests were conducted with both solid and flexible test sections in a test vessel filled with room temperature water. Pressure pulses of magnitude up to 1150 psid and durations from 6 to 47 msec were generated with a drop hammer and piston pulse generator.nFLASH-34 calculations show good agreement with the test data. In particular, FLASH-34 adequately predicts the decrease in peak pressure and the increase in pulse duration due to the presence of a flexible test section. Both test data and FLASH-34 calculations snowed the structural response to be approximately quasi-static, except for slight departures from quasi-static response for the most rapid pressure pulses. All of the structural responses were in the elastic range.
