Ansys Software Helps Ferrari Improve Comfort

Italian car manufacturer Ferrari is using software from Ansys to optimise automobile design and performance. Ferrari is using software from Ansys to predict thermal comfort in a vehicle's interior. In order to assess comfort qualitatively and quantitatively, the car manufacturer worked with Pisa University in Italy to define thermal comfort indices and to evaluate the general aspects of thermal comfort. Since an experimental approach was not practical, the investigating engineering team used fluid dynamics software from Ansys to perform the calculations. According to Giovanni Lombardi, professor of aeroplane aerodynamics and vehicle aerodynamics at Pisa University, the Ansys engineering simulation software rendered accurate and reliable results. The research team based its resulting 'global thermal comfort index' on several local indices: the thermal equilibrium of the human body, discomfort caused by drafts and horizontal and vertical temperature gradients. Various factors were studied, including the car's velocity and materials (leather, glass and aluminium) as well as sensitivity to warming or cooling on various body sites (leg, arm and face, covered with clothing or not), solar irradiance, vehicle interior size and air flow. 'The advantage of simulation-driven product development is that no complex physical models or testing configurations are required and the design can be tested, optimised and, if necessary, modified virtually at an early stage in the development process,' said Jim Cashman, president and chief executive of Ansys.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
