The electric discharge was initiated using a PIV-100M standard capacitor-based blasting device. Based on the analysis of oscillograms of the electric current and voltage drop across the bridge, the resistance of the bridge and the power of Joule losses therein depending on time have been determined. In the model approximation, the mass of the exploding part of the bridge and the specific energy coefficient of the resistance of the bridge material before the onset of melting have been obtained. This approach can be used to find the optimal dimensions of the bridge, to determine its thermophysical parameters in the course of an electric explosion, and to study the electrical properties of other low-melting materials that are promising for making a safe industrial detonator.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"53 7","pages":"845 - 851"},"PeriodicalIF":0.4,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142761953","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}

Using the example of the simplest zero-mobility groups — planar dyads (two-bar groups) and screw monads (one-bar groups) — we demonstrated a synthesis algorithm, which consists of setting these groups between two links, combining them into a closed kinematic chain. When we fix any of the links in such a chain, we obtain a workable mechanism. This algorithm considers two possible options for the relative arrangement of planar- and screw-type kinematic chains. Based on the developed algorithm, we synthesized a family of five-bar planar-screw one-DOF mechanisms. We confirmed the competence of the presented algorithm by performing a mobility analysis of one of the synthesized mechanisms.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"53 7","pages":"686 - 692"},"PeriodicalIF":0.4,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142761829","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}
