By measuring the strain on the pressure bar and the particle velocity on the rear-end face, the shock wave pressure applied on the front-end face of the pressure bar was calculated based on one-dimensional stress wave theory. On the other hand, a calibration method was designed to validate the reliability of the test system. Based on the split-Hopkinson pressure bar (SHPB) loading experiment, the transmission characteristics of stress wave in the bar and the accuracy of the system test results were verified. The results indicated that the stress wave measurement results were consistent with the one-dimensional elementary theoretical calculation results of stress wave propagation in different wave-impedance materials, and the peak deviation measured by PDV and strain measurement method was less than 1.5%, which proved the accuracy of the test method and the feasibility of the calibration method.<\/jats:p>","DOI":"10.3390\/s25154743","type":"journal-article","created":{"date-parts":[[2025,8,4]],"date-time":"2025-08-04T16:41:54Z","timestamp":1754325714000},"page":"4743","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Shock Wave Pressure Measurement and Calibration Method Based on Bar Pressure Sensor"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-1465-9887","authenticated-orcid":false,"given":"Yong-Xiang","family":"Shi","sequence":"first","affiliation":[{"name":"Northwest Institute of Nuclear Technology, Xi\u2019an 710024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4059-2091","authenticated-orcid":false,"given":"Ying-Cheng","family":"Peng","sequence":"additional","affiliation":[{"name":"Northwest Institute of Nuclear Technology, Xi\u2019an 710024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2803-8973","authenticated-orcid":false,"given":"Yuan-Ding","family":"Xing","sequence":"additional","affiliation":[{"name":"Northwest Institute of Nuclear Technology, Xi\u2019an 710024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2119-5519","authenticated-orcid":false,"given":"Xue-Jie","family":"Jiao","sequence":"additional","affiliation":[{"name":"Northwest Institute of Nuclear Technology, Xi\u2019an 710024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-5182-1661","authenticated-orcid":false,"given":"Xiao-Fei","family":"Huang","sequence":"additional","affiliation":[{"name":"Northwest Institute of Nuclear Technology, Xi\u2019an 710024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8153-3878","authenticated-orcid":false,"given":"Ze-Qun","family":"Ba","sequence":"additional","affiliation":[{"name":"Northwest Institute of Nuclear Technology, Xi\u2019an 710024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,1]]},"reference":[{"key":"ref_1","unstructured":"Zhang, Y.P., Chi, J.C., Gong, Y.Q., and Wang, G.J.
