Design for Extrusion

Driving designs that are cognizant of the downstream manufacturing processes Increasing manufacturing costs and stiff competition coupled with low profit margins are posing tremendous challenges to extrusion companies, especially automotive and aerospace industries. One way the leading companies stay ahead of the competition is by reducing the product development time and production costs through virtual testing. Design engineers and analysts use CAE software to analyze and validate die designs and thereby reduce/eliminate costly die trials. This webinar explains how extrusion simulation framework provides an easy to use CAE environment to: - Validate extrusion die designs - Optimize process conditions - Identify potential defects and correct them before becoming critical problems

E-Motor Weight and Cost Reduction Webinar

Nowadays, it is more and more challenging to design an e-motor. Many constraints have to be fulfilled, including maximizing power using minimal size, considering thermal constraints, material and production costs, and of course reducing weight. In order to meet these constraints, a multifaceted solution is needed, leveraging physics tools in combination with optimization methods. This webinar will introduce Altair's e-motor design and optimization solutions in a step by step process. We will discuss pre-design, magnetic computation and thermal analysis and show how optimization methods can help to optimize weight and cost at each step of the process (especially the weight of magnets) . We’ll demonstrate how Design Of Experiments (DOEs) allows designers to run different types of optimization very quickly, which enables informed decisions at different stage of the design cycle.

OptiStruct - Equivalent Plastic Strain Response for Optimization

Equivalent plastic strain can be used as an internal response when a nonlinear response optimization is run using the equivalent static load method. This is made possible through the use of an approximated correlation between linear strain and plastic strain, which are calculated in the inner and outer loops respectively, of the ESL method.

OptiStruct - Neuber Optimization Response in Nonlinear Subcase

Neuber Stress and Neuber Strain sensitivities are supported for optimization in small displacement NLSTAT. It was already supported for optimization in FASTCONT analysis. It is supported only for small displacement analysis, it is not supported for large displacement. Once Neuber response is defined, the material will be treated as linear and MATS1 props are used only for Neuber correction. It is supported for solids as well as shells. It is supported for all optimization types except topology & freesize optimization.

Improving Electric Vehicle Range with Advanced Losses Computation Considering PWM Across a Full Duty Cycle

Introducing electric traction in automotive brings new challenges for the design of electric machines. Nowadays designers have to consider increasing constraints like efficiency, temperature, weight, compactness, cost but also stricter regulations, while reducing time to market. Fortunatly, Altair proposes disruptive methodologies to make relevant choices in the early stage of the design, based on numerical simulation and optimization techniques. Once the machine has been selected and designed in Altair FluxTM this webinar covers how an electric motor design's performance is evaluated and maximized considering its global efficiency along the whole driving cycle. The next design challenge is to get an accurate estimation of the losses, which becomes more and more strategic in the design process in order to accelerated speed to market with balanced design and confidence. This estimation is also a key issue of thermal design. Therefore, the study of losses (in particular non-conventional losses) is crucial. Two methods are proposed to take the current wave form into account: by using an equivalent circuit model in Altair ActivateTM system modelling software, or by representing the PWM in Flux circuit context.
