A movable sunshade on the roof of the Milwaukee Art Museum consists of a pair of wing-like structures, each made up of 36 steel ribs ranging in length from 24 to 105 ft. The ribs are mounted on two rotating steel shafts, in turn connected to the pavilion's spine. To open and close the sunshade, 22 hydraulic cylinders (11 on each side) stroke simultaneously. The cranks swing a 90-degree. arc to open the wings in 3.5 minutes. Engineers equipped the building with two separate ultrasonic wind sensors to monitor velocity and direction. If wind speed exceeds 23 mph for three seconds or longer, the control system automatically closes the wings. Similarly, a lightning sensor is installed to predict imminent lightning strikes. The power unit consists of two identical pump sets. Each 30-hp motor drives a tandem axial-piston pump. One pump of each tandem set powers the north wing, the other powers the south wing. This circuit can move both wings even if one motor/pump group is out of service.
Our LinkedIn systems and product design engineering group discusses if they are happy with their decision of remaining a technical contributor instead of becoming a manager.
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.
