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.

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.

5 ways to optimize your design

Gauge optimization, size and shape, and shell optimization, can be used to improve an existing design without altering its overall architecture. 3D topology optimization can be used when a significant re-design is desired because it identifies the optimal load paths of a structure and recommend material reduction. The material layout produced in the 3D topology is then interpreted into a concept design which is dimensioned and fine-tuned with the gauge, size, and shape approaches resulting in a final structure.

OptiStruct Lessons Learned from a Cambered Structure with Welds made Post-Decambering using Modchg

Problem Description - A pre-cambered trailer is loaded to nearly flat under 1g down by a permanent payload (large steel transformer oil reservoir box). - As the payload is loaded, the trailer is 'de-cambered." They payload is then welded in place to the trailer. - Other operational load cases are applied as the subsequent load cases to the de-cambering load. Topology optimization is conducted with responses from both de-cambering load case and subsequent load cases. - All subsequent analysis must take into account the de-cambering held in place by the welds. The de-camber is a "large displacement" formulation and the loading happens via sliding contact with the payload box.
