Based on the fundamental cause, a unified expression of the solution for the magnitudes of the constraint wrenches of both the limb stiffness decoupled and limb stiffness coupled overconstrained PMs is derived. When the weight of each link is considered, depending on whether additional component forces are generated along the axes of the overconstrained wrenches, two different situations should be considered. One situation is that no additional component force is generated along the axes of the overconstrained wrenches under the weight of the links in the corresponding limb. In this case, the added constraint wrenches at the limb\u2019s end can be calculated directly, and used as a part of the generalized external wrench. The other situation is that additional component forces are generated. In this case, the elastic deformations in the axes of the overconstrained wrenches generated by those component forces should be considered, and the deformation compatibility equations between the overconstrained wrenches are reformulated.<\/jats:p>","DOI":"10.1017\/s0263574719000109","type":"journal-article","created":{"date-parts":[[2019,2,18]],"date-time":"2019-02-18T01:26:07Z","timestamp":1550453167000},"page":"1533-1544","source":"Crossref","is-referenced-by-count":1,"title":["Principle of Force Analysis of Overconstrained Parallel Mechanisms Considering Link Weight"],"prefix":"10.1017","volume":"37","author":[{"given":"Yundou","family":"Xu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ling","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenlan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinwei","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiantao","family":"Yao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongsheng","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2019,2,18]]},"reference":[{"key":"S0263574719000109_ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s11071-014-1739-9"},{"key":"S0263574719000109_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.rcim.2012.05.003"},{"key":"S0263574719000109_ref15","doi-asserted-by":"publisher","DOI":"10.1002\/rob.4620090707"},{"key":"S0263574719000109_ref4","doi-asserted-by":"publisher","DOI":"10.1115\/1.1901708"},{"key":"S0263574719000109_ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.sna.2008.11.030"},{"key":"S0263574719000109_ref31","doi-asserted-by":"publisher","DOI":"10.1007\/s10033-017-0199-9"},{"key":"S0263574719000109_ref5","first-page":"1","article-title":"Variable motion\/force transmissibility of a metamorphic parallel mechanism with reconfigurable 3T and 3R motion","volume":"8","author":"Gan","year":"2016","journal-title":"J.
