Form and Function: Metal 3D Printing of Hybrid Lattice

Altair, Materialise and Renishaw have collaboratively created a prototype of lattice structured spider bracket; a lightweight, functional structure which echoes biological forms found in nature. The synthesis of computational design technology with performance based lattice optimization, automatic surface smoothing and re-design with metal additive layer manufacturing, resulted in the creation of this unconventional, structurally efficient, manufacturable bracket that unleashes designing potential and creativity, freeing creators of common manufacturing constraints across the entire project from conception, product performance to its realization. The printed part shows how true bio-mimicking of 3D patterns reduces stress concentrations and produces a custom tailored design that embeds organic beauty and freedom of design.

Mechatronic Systems Engineering: Altair’s Multibody Solutions

Altair’s MotionSolve is a powerful multi-body solution to help simulate mechatronic systems. Integration with solidThinking Activate allows a user to model control systems, actuators and sensors in a convenient block diagram environment while coupled with MotionSolve via co-simulation. Models in MotionSolve can be linearized for classic control system design, and its powerful non-linear capabilities helps you model critical effects, ranging from friction, to component flexibility, to contact between colliding bodies. Additional capabilities for integration with Fortran/C/Python, and support for Modelica and Functional Mock-up Interface standards allows different domains and third-party tools to be used as needed. Finally, integration with other HyperWorks tools allow you to drive your simulations with a model-based design approach.

High Performance Computing Speeds-up Optimization Processes for Tailor Rolled Blanks at Mubea

OEMs and suppliers include every possible technique to support lightweighting in the automotive industry. It is common to use optimization techniques in order to identify and tab existing lightweight potentials as well as design tailor rolled components in a vehicle, the design optimization of which is normally based on crash simulations. Due to the large size of these simulations, a single run can take 1 to 12 hours. To conduct all the simulation runs needed for assessment and evaluation of different design concepts, the use of HPC is necessary. HWUL- VA was able to reduce the turnaround time for a lightweight study significantly at Mubea.

Using Analytical Approach with Finite Element Analysis for Coupling Magnetic and Thermal Analysis for Motors

Thermal analysis is a key factor when designing motors. We propose to link the studies of
electromagnetic and thermal aspects in transient application with Finite Element Method (FEM) to
represent the thermal state of motor with higher accuracy. As electromagnetic response time is
different of thermal response time, an original method is used for extracting average values on one
magnetic period of losses (Joule and iron losses), and to use them as input for the transient thermal
analysis. So, the temperature in different parts of the motor is extracted, and brought back as input
for the next electromagnetic computation.

Numerical Modeling and Experimental Analysis of the Magnetic Noise of the Single-Phase Inverter-Fed Permanent Split-Capacitor Motor_Andrei NEGOITA_OPTIM

Abstract- The paper presents a FEM approach for studying the influence of the capacitor value on the magnetic noise of a network and inverter-fed permanent split-capacitor induction motor. A 4 pole, 24 stator slots and 30 rotor slots, induction motor is modeled under Flux2D Finite Element software in order to determine the amplitude and frequency spectrum of the magnetic forces acting on the stator. The effects of the inverter supply are taken into account by coupling Flux2D with Matlab/Simulink. The results are compared with those obtained from noise measurements performed on the studied motor.

This research work describes the permanent magnet linear machines, their characteristics, control and applications. It aims to develop a linear machine model in finite element based software, Flux2D. The Finte Element Method (FEM) model consists of 8 poles and 9 slots where periodicity of poles is used to simulate inifinite travel length. The no-load and nominal load conditions are also simulated to validate the performance of the model. At no-load, the cogging force is simulated and is found to be 1.1N
