Part Positioners

Yaskawa Motoman (Dayton, OH) expanded its line of RM2 ferris wheel-style robotic part positioners. The positioners have two servo-driven trunnion/station axes on opposite sides of a central “sweep” axis. One station is positioned in front of one to four welding robots, while the other station is outside the robot envelope where the operator loads/unloads parts. The 180° sweep axis rotates the stations over/under the central axis between the robot(s) and the operator. Slim-Line positioner models have a 17% smaller width than standard positioners, and are available with 755-kg and 1,255-kg payload capacities. Extra-large-capacity positioners were designed to provide higher payloads and turning diameters in a reduced profile, and feature 1,555-kg and 2,355-kg payload capacities.

Optical Encoders

MICROMO (Clearwater, FL) announced the FAULHABER high-precision IER3 and IERS3 optical encoders. Both encoders deliver two-channel quadrature signals and an additional index signal. They can position a FAULHABER micro DC motor or brushless DC servomotor with a typical accuracy of 0.1° to 0.3°. The encoders combine the LED, photodetectors, analysis unit, and interpolation levels on one chip. They lengthen motors by 15.5 to 18.5 mm. Both encoders are also available with line drivers that generate complementary output signals and make data transmission resistant to electrical interference, especially in encoders with long connecting cables. The IER3 encoder has a resolution of up to 10,000 lines per revolution, and achieves an angular resolution of 0.009° with the evaluation of 40,000 edges per revolution. The IERS3-500 provides resolutions of 250 and 500 lines per revolution.

Product of the Month: December 2016

ANSYS AIM 17.2 simulation software from ANSYS, Pittsburgh, PA, features combined fluid thermal and solid thermal-stress capabilities. Momentum and heat sources are available for fluid and conjugate heat transfer analysis, enabling simulations to include such features as electronic package power sources, fans, and filters. New options for optimizing bolted connections allow engineers to model loading and bolt tightening sequences for structural assemblies. Integrated geometry modeling enables users to open data from any CAD system for simulation. Automated meshing tools allow rapid generation of meshes for complex geometries. A flow solution evaluates parameters such as reducing pressure drop, calculating lift and drag coefficients, and evaluating fluid loads. Other features are stress, vibration, and durability analysis; electromagnetic simulation; and simulation of polymer extrusion manufacturing.

NASA's Software Answers Big Questions About Space and Earth

NASA-developed software tools provide modeling and simulation methods that tackle some of the toughest science and engineering challenges in aerospace, space exploration, and our knowledge of Earth. Simulating the SLS Sound Suppression Water SystemNASA’s next-generation Space Launch System (SLS) for deep space exploration consists of four RS-25 liquid rocket engines and two five-segment solid rocket boosters (SRBs). At ignition, the SRBs create a significant over-pressure event, known as the Ignition Over-Pressure (IOP) event. The IOP event experienced in the first space shuttle flight (STS-1) in 1981 damaged the space shuttle orbiter and motivated significant design changes to the launch pad at NASA’s Kennedy Space Center. The RS-25 liquid rocket engines aboard the SLS, along with the SRBs, also create a very significant acoustic environment that, if not mitigated, can harm the SLS launch vehicle. An Ignition Over-Pressure/Sound Suppression (IOP/SS) water system was developed to reduce the amplitude of both the IOP event and the acoustic environment caused by the firing of the RS-25 engines and the SRBs.

Temperature Sensors Cement the Integrity of Bridges

Thermal profilers, developed with NASA, ensure structural integrity of cement as it cures.The Obama administration wanted to foster partnerships with small- to medium-sized manufacturers through its Strong Cities, Strong Communities Initiative, wherein Federal agencies around the country are asked to mentor local businesses. One of the communities selected was the Cleveland-Youngstown region of Ohio, resulting in a call to Glenn Research Center. The Adopt a City program was launched, in which eight companies were identified to receive 40 hours each of assistance from experts at Glenn.
