Multidisciplinary Workflow to Assess Modal Fatigue Results of a 4-Cylinder Crankshaft with EXCITE-OPTISTRUCT-FEMFAT
The crankshaft of an engine is a highly dynamically loaded component that is continuously optimized and optimized in terms of design and production technology. In order to be able to reproduce this in the simulation, the essential influences must be considered. This includes the dynamically behaviour in combination with the engine, the material properties and the application of the loads and their transfer to other parts (bearings).
The modal approach has established itself as a proven method here, whereby a modal basis is determined in the FEM so that the crankshaft is integrated as a flexible body in the MKS model of the engine, and so that an entire engine run-up can be simulated. The modal participation factors are obtained from the MBS simulation, which are used together with the modal stresses for the safety factor calculation.
This workflow requires the combination of different simulation tools. The challenge is to organize the data transfer between the tools efficient and correct. In this example, the workflow is realized using Optistruct from ALTAIR for FEM calculation, EXCITE from AVL as MKS tool and FEMFAT from ECS as Fatigue solver.
This makes it possible to simulate a complex engine run-up with consideration of the ignition bearing forces and to calculate the fatigue life of the crankshaft in FEMFAT.
This live webinar, details of the simulation workflow of the 4 cylinder crankshaft will be presented and the effects of several influencing variables on the fatigue life will be studied.

Simulation of Cavitating Flows and Gas Bubble Transport with DSHplus
The occurrence of cavitation negatively affects the performance of hydraulic systems. The impairments range from increased noise levels to severe and life-limiting wear of machine parts. Cavitation in hydraulic systems can be prevented by early integration of one-dimensional fluid power simulation software into the design process.
In this webinar, FLUIDON’s piping expert “RohrLEx” explains how cavitating flows can be simulated with the updated component models of DSHplus. The improved models enable the user to analyze all relevant types of cavitation – vapor cavitation, gas cavitation and pseudo-cavitation – as well as the associated phenomenon of gas bubble transport.
To illustrate the workflow when simulating a cavitation-endangered and/or gas conveying system with DSHplus, two exemplary cases are presented and discussed.

Concept Design for Plastic Parts - Better and Earlier Decisions with CAE Driven Design
Traditionally, products are created with a draft, which is then specified by taking into account external factors. The next step is to validate, test them as prototypes and adapt the design. If simulation is used as a virtual test, this cycle can be accelerated.
The foundation for a successful design is set in the concept phase.
This raises the question of how simulation can be used as a motor for creative solutions and how it can be used as a groundbreaking basis for decision-making in the early phase of product development.
With the simulation-driven design approach, you can achieve early design maturity, efficient material utilization and shorter development times in the development of complex plastic components. Using the example of a front-end module, Code Product Solutions and Altair will demonstrate efficient product development in the recording "Concept Design for Plastic Parts".

Battery & Motor Thermal Management for Electric Vehicles
The key element of an electric vehicle (EV) is the battery and batteries are known to produce heat during their charge-discharge cycle. An efficient thermal management system (TMS) is of paramount importance. The battery TMS affects the cost, life, and range of the EV. A battery TMS study or an EV TMS study involves the use of thermal and fluid physics and Altair’s AcuSolve (Computational Fluid Dynamics based Simulation Technology), was used to carry out this study. The importance of finding new methods for effectively and accurately designing TMS that control temperature and optimize the performance of Li-ion batteries. This can be used to study and optimize the Battery Thermal Management System and other Thermal Management requirements arising in an electric vehicle which involves both active and passive cooling. A similar issue of heat (unwanted) exists in Motors as well, in this, we shall cover the Multiphysics simulation of Motors which shall include both electromagnetics and CFD Thermal studies of both air and liquid coolant motors.

NVH Refinement for Electric Vehicles
Replacement of traditional combustion engines with an electric powertrain, bring electro-mechanical induced tonal and high-frequency whine noise. In addition, tire and aerodynamic turbulent noise become more prominent in the absence of a standard Internal Combustion Engine. Also, the perceived sound quality imposes a new set of challenges. This leads to completely new methods of NVH refinement, keeping the decades of research aside. As it is important to address these issues at the design and development stage, adopting the new simulation techniques to manage future NVH challenges in e-Mobility is of the prime challenge to the traditional NVH engineers. In this webinar, we shall discuss some of those key NVH challenges specific to electric vehicles and appropriate simulation processes to develop countermeasures.
