The kinematic chains of parallel manipulators share the loads and make the stiffness higher than the stiffness of serial manipulators with equivalent limbs. This high stiffness ensures a minimal deformation of the limbs, allowing a high positioning accuracy of the endeffector. Thus, it is very important to be able to measure the stiffness in parallel manipulators. In this work, we present a novel 1T2R multi-axial shaking table (MAST) for automobile pieces testing purposes\u2014the 2PRU\u20131PRS parallel manipulator\u2014and focus on the analysis of its stiffness all over the useful workspace. Analysis methods based on matrix structural method need to be validated for every parallel manipulator, and we present these steps along with a comparison between experimental and analytical methods.<\/jats:p>","DOI":"10.1017\/s026357471900002x","type":"journal-article","created":{"date-parts":[[2019,1,31]],"date-time":"2019-01-31T07:31:42Z","timestamp":1548919902000},"page":"1401-1414","source":"Crossref","is-referenced-by-count":7,"title":["Analytical Procedure Based on the Matrix Structural Method for the Analysis of the Stiffness of the 2PRU\u20131PRS Parallel Manipulator"],"prefix":"10.1017","volume":"37","author":[{"given":"Saioa","family":"Herrero","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles","family":"Pinto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3364-5003","authenticated-orcid":false,"given":"Mikel","family":"Diez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javier","family":"Corral","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2019,1,31]]},"reference":[{"key":"S026357471900002X_ref9","first-page":"4213","volume-title":"Proceeding IEEE International of the Conference on Robotics and Automation","author":"Deblaise","year":"2006"},{"key":"S026357471900002X_ref13","doi-asserted-by":"publisher","DOI":"10.1109\/70.56657"},{"volume-title":"14th World Congress in Mechanism and Machine Science.
