These guide systems are made for high speed and low cost. The Speed Demon OSG type and Speed Demon SG type systems run up to 10m per second (32.8 ft/sec), accelerate at up to 50 m/sec squared, and take loads up to 5,600N, or 1,259 lb. The OSG systems have five rail and block sizes, while the SG systems have seven rail sizes and 19 block designs. The rails in both systems have pre-drilled mounting holes, dual RC60 steel shafting and come in lengths up to 4m (13 ft), but can be ordered cut to size. The OSG blocks have four dual-contact roller bearings with two bearing on eccentric mounts, while the SG blocks have one, two or three bearings. OSG running straightness is +/- 0.02 mm (+/- .0008 inches), and the SG's is +/-0.015 mm (+/-.0006 inches). Both systems use felt wipers, high-angular dual-contact bearings, and corrosion-resistant materials. LM76http://rbi.ims.ca/4928-627
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
