Formalization of the analysis is accomplished by introduction of the concepts of the kinematic “influence coefficients” of velocity, acceleration, force, power inertia, etc., thereby making optimization through digital programming more feasible. It is possible to determine the response of mechanical systems to known energy, force, or power crossing the boundaries through the utilization of these influence coefficients. The effect of coulomb friction on the response is also shown to be predictable, a feature which enables the designer to better analyze or design mechanically constrained systems.</p></div>","PeriodicalId":100802,"journal":{"name":"Journal of Mechanisms","volume":"6 4","pages":"Pages 383-403"},"PeriodicalIF":0.0,"publicationDate":"1971-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0022-2569(71)90042-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91764628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
