<\/a>d algorithms to assist in parametric analysis.\u00a0 This month the two-year project, which began in July 2013, is approaching an important milestone.\u00a0 As the UConn researchers are putting together a system-level dynamic model, Stanley Black & Decker is developing a test bed that will enable the researchers to collect data from a prototype.<\/p>\nLehnert explains, \u201cThe prototype has been fabricated and the process has been documented. The next step is to physically test the prototype and to compare the actual performance against the model\u2019s prediction. A good analogy is the odometer in your car. You don\u2019t know how accurate it is until you calibrate it against a known distance. The predictive model will have to be calibrated and aligned with the real performance of the prototype impact wrench. After the model has been properly aligned at the system level, we will carry out detailed component analysis, which will allow us to predict wear and durability.\u201d<\/p>\n
When complete, this process will be repeated, step for step, for the air hammer.\u00a0 Air, or pneumatic, hammers exploit a compressed air and piston system to produce a rapid-fire movement of a piston much like that of a woodpecker drilling for insects on a tree. \u00a0Air hammers are commonly used to hammer nails, cut metal, engrave ornamental designs onto materials or drill holes.<\/p>\n
For Stanley Black & Decker, this industry-university collaboration promises to enable the company to develop more customized, durable tools on a dramatically reduced time-to-market cycle. As the nation redoubles its support for a revival in American manufacturing, academic-industry partnerships are likely to gain increasing momentum.<\/p>\n","protected":false},"excerpt":{"rendered":"
Drs. Jiong Tang and Chengyu Cao are collaborating with engineers at global tool giant Stanley Black & Decker to create a methodology to analyze the precise mechanism of tools in two of the company’s product lines, impact wrenches and air hammers, as the key step in developing software capable of shortening the company\u2019s new product development cycle and enhancing the product performance.<\/p>\n","protected":false},"author":122,"featured_media":224291,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_crdt_document":"","wds_primary_category":0,"wds_primary_series":0,"wds_primary_attribution":0,"footnotes":""},"categories":[1866],"tags":[],"magazine-issues":[],"coauthors":[56],"class_list":["post-17772","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-engr"],"pp_statuses_selecting_workflow":false,"pp_workflow_action":"current","pp_status_selection":"publish","acf":[],"publishpress_future_action":{"enabled":false,"date":"2026-04-15 14:42:31","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/17772","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/users\/122"}],"replies":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/comments?post=17772"}],"version-history":[{"count":1,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/17772\/revisions"}],"predecessor-version":[{"id":224292,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/17772\/revisions\/224292"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media\/224291"}],"wp:attachment":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media?parent=17772"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/categories?post=17772"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/tags?post=17772"},{"taxonomy":"magazine-issue","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/magazine-issues?post=17772"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/coauthors?post=17772"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

<\/a>ches are widely used in infrastructure construction, manufacturing assembly, machine repair and other industrial applications requiring a high torque output. According to Tang, a professor of Mechanical Engineering, the basic mechanism was invented over 80 years ago and exploits the impact momentum produced when an internal hammer is rotated by a motor at an accelerating rate before striking an anvil. The force of the strike results in an impact causing high torque that far exceeds what could be produced solely by the motor, and after striking the anvil, the hammer is quickly retracted and again spun by the motor. In response, the bolt or screw tightens.\u00a0<\/p>\n![\"bd2b\"](\"http:\/\/d45h139.public.uconn.edu\/sites\/news\/wp-content\/uploads\/bd2b.jpg\")
