  • Simulations of a Truck Crashing Into a Reinforced Concrete Wall

    Kiewit Corporation, a diverse company specializing in construction, mining, oil, gas, power, transportation, and water projects, was contracted to design a boundary wall around a large electrical switching station. One of the requirements of the design was to prevent a medium duty truck from penetrating through the wall, as detailed in the crash test specifications of ASTM F2656-07. Kiewit contacted CAE Associates to request dynamic structural analyses to simulate the wall impact events for two different wall designs at different impact angles and locations.

  • Optimization of a Test Rig Platform

    Mechanical Solutions Incorporated designed a platform for testing axial fans at different speeds. The platform was designed to avoid any natural frequencies within the test speed range of the fans. A number of design iterations were required until a design was proposed that could satisfy the frequency criteria (safety margin from major excitation sources) without creating an excessively large and heavy structure.

  • Solving Coupled Power and Signal Integrity Problems

    LSI Corporation uses ANSYS tools to model the behavior of a system on a chip (SOC) under load; engineers also diagnose and solve both power integrity and signal integrity issues in a single environment. LSI designs semiconductors and software that accelerate storage and networking in datacenters, mobile networks and client computing. The company developed a methodology to address power and signal integrity issues in a holistic manner by leveraging ANSYS chip–package–system solutions.

  • Optimizing Body-Worn Wireless Devices

    Using a wireless device in close proximity to the human body creates a number of major design challenges. The radiated power of the device must be kept below levels that can create a health hazard. The device’s power consumption, size, aspect ratio and weight must be minimized to make it suitable for wearing. Yet the device must be designed to deliver a signal of sufficient power to the right location, with good reception by the target device — despite the fact that the human body may absorb a significant portion of the signal.

  • ANSYS Saves Time & Money When Designing PCBs

    Interconnect Engineering Inc. has long used and supported ANSYS electronic design tools, this project provided the opportunity to put the new ANSYS Electronics Desktop to the test. This tool provided a major advantage in this application by reducing the amount of time required to analyze the design in both the time and the frequency domains. The Electronics Desktop integrates EM tools, circuit/system simulation, ECAD links and compliance reporting. This new technology delivers a single desktop for system simulation  design.

  • Static Mixer Fatigue Life Assessment with ANSYS Mechanical

    The Norsea Gas Terminal in Northern Germany plays a vital role in the connection of pipeline systems coming from the North Sea to the natural gas distribution network throughout Germany. Built in 1977, the terminal was set to be replaced in 2015 by the GASSCO Emden terminal being built by Linde Engineering to ensure the continued safe and reliable delivery of natural gas to the region.

  • Multiphysics Analysis of Electromagnetic Actuators (Solenoids)

    Electromagnetic actuators, or solenoids, are devices that operate by producing magnetic fields to move an armature a desired distance at a desired force. They are used in applications such as fuel injectors, power distribution (interrupters, breakers, etc.), and various automotive, hydraulic and industrial applications.

  • Temperature-Dependent Permanent Magnets

    The demagnetization characteristic of permanent magnets is temperature dependent. Therefore, the performance of any device working with permanents magnets varies with temperature. In situations in which these devices are subject to large temperature variations, analysis must ve carried out at different temperatures to predict possible performance deterioration.Temperature-dependent permanent magnet models in ANSYS Maxwell can be applied to simulate the electromechanical performance of various devices.
