The WLAN Dual-band antennas are integrated onto the printed circuit board (PCB). The impedance matching bandwidth must be wide enough for the antenna to perform well in various locations.
By using ANSYS HFSS and ANSYS optiSLang, the influence of various geometric parameters on antenna performance can be evaluated. This helps optimize resonance frequencies, bandwidths, antenna gain, and understand the impact of manufacturing tolerances and different mounting locations. New layout concepts are studied with ANSYS SIwave, particularly optimizing the layout of power and ground planes and the positioning of decoupling capacitors.

In this way, capacitors are saved, and new design rules are established. Signal integrity analysis using ANSYS SIwave shows the potential savings for termination resistances and helps optimize high-speed critical signal lines.

Under load, plastic components in washing machines exhibit time-dependent effects such as creep and stress relaxation, in addition to plasticity.
In collaboration with CADFEM, Miele conducted a study to determine the material behavior and subsequently adjust its parameters.
ANSYS Workbench and ANSYS DesignExplorer were used to solve this problem, with which a general workflow was developed. Minimizing the force difference between test and simulation values was the methodological basis.

Thermoforming is widely used for mass production of refrigerator liners. The variation in the thickness distribution of the liner is an important quality parameter that has traditionally been controlled by trial and error. This typically involves choosing different sheet thicknesses and process parameters (temperature, pressure, etc.), resulting in material waste and production time loss.
A thermoforming simulation could quickly and efficiently predict the thickness and distribution of the liner, eliminating material waste and production time.

Engineering Solution:

– ANSYS Polyflow provides different equations to model deformation velocity and viscosity temperature dependence.
– ANSYS Polyflow offers various material models and contact algorithms to effectively reproduce the thermoforming process and predict accurate results.
– Polyflow’s adaptive meshing helps refine the mesh of the sheet as it comes into contact with the mold to closely follow the mold’s geometry.

After thorough research on simulation software to better meet evolving needs, V-ZuG found that ANSYS structural mechanics software, supported by CADFEM, its local ANSYS partner, best met its requirements.

Problem 1:
V-ZuG was using ANSYS software to simulate an oven door made of steel, incorporating a glass window glued to the frame. Originally, when the oven operated at high temperatures, the glass would break under thermal loads. To simulate the problem, the engineer imported the door geometry from CATIA into the ANSYS Workbench platform and simulated the thermal load using the ANSYS DesignSpace tool. The simulation results matched those of the prototype, with the highest stresses occurring at the corner where cracking began. The V-ZuG engineer then simulated the performance of various glass materials in ANSYS DesignSpace to identify a material capable of withstanding thermal loads.

Problem 2:
Washing machine developers increased the capacity of the machine from 5 to 8 kg of dry laundry. This change necessitated the development of a vibration absorption system; otherwise, the 8 kg spin cycle would take up too much space in the casing. The engineer simulated the new design using ANSYS Mechanical software.
