Problems solved by technology

[0002] Existing bulging test equipment for the performance of specimens is characterized by the displacement generated by the bulging, but the displacement is only caused by the bulging of a small area of ​​the specimen, not the entire surface of the specimen, so the use of displacement to characterize the performance of the specimen is too one-sided. And there will be deviation due to the action of friction force in the process of displacement transmission

Abstract

The invention discloses a hydraulic bulging testing device, which comprises: a base, a liquid filling tank is arranged on the top, a liquid filling port is provided on the bottom to communicate with the liquid filling tank through a channel; the liquid filling tank is provided with a platform for installing a test sample, The test sample cover is set on the notch of the liquid filling tank to form a liquid filling chamber; the flexible curved surface sensor is attached to the upper surface of the test sample to sense the shape of the curved surface of the test sample after swelling and deformation; the pressure ring is installed on the flexible around the curved surface sensor, and cooperate with the platform to fix the tested piece and the flexible curved surface sensor; the upper cover, the cover is arranged above the liquid filling tank, and is offset against the upper surface of the pressure ring, and the upper cover is provided with a through hole communicating with the pressure ring, and The upper cover is provided with a threading hole; the controller is connected with the flexible curved surface sensor and is used to receive the signal collected by the flexible curved surface sensor to form a sample deformation surface map. Performance measurement accuracy.

Description

technical field [0001] The invention relates to the technical field of bulging experiments, in particular to hydraulic bulging testing equipment. Background technique [0002] Existing bulging test equipment for the performance of specimens is characterized by the displacement generated by the bulging, but the displacement is only caused by the bulging of a small area of ​​the specimen, not the entire surface of the specimen, so the use of displacement to characterize the performance of the specimen is too one-sided. And it will produce deviation due to the action of friction force in the process of displacement transmission. Therefore, how to provide a testing device capable of comprehensively characterizing the deformation of the specimen surface has become an urgent problem to be solved in this field. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic bulging test equipment to realize the comprehensive characterization of ...
