This platform runs on a rolling ring drive and reciprocates automatically without motor reversal. Linear speed can be adjusted on the fly with a control knob on the assembly, without changing speed or reducing gears. No electronics or programming is needed - speed and travel direction are controlled mechanically. The platform is low maintenance, with no hydraulics or pneumatics, and only a light shaft lubrication once every three months in the linear drive. Adjustable end stops can increase or decrease length of travel. Precision-machined components limit vertical and horizontal platform movement to within ± 0.001 inches, and rolling ring bearings compressed against the shaft inside the drive make for zero play and backlash-free motion. A modified reversal mechanism makes for smooth, jarring and jerking-free reversal.
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.
