When discussing the benefits of simulation, time and money savings are usually the biggest headlines, as they should be. But these also promote better design. To avoid multiple iterations and meet design specifications, engineers tend to design conservatively, as was the case at TürkTraktör (Turkey’s largest producer of tractors). The problem with this approach is …
Cars, even when driven by careful drivers, will almost definitely experience misuse, peak load or strength events, such as driving over a curb or skidding against a curb a few times during their lifetimes. These durability load cases play can significantly influence the design for several components. At Volvo, the “driving over a curb” and …
Bolted or riveted airframe assemblies are typically modeled as continuous meshes. But advances in meshing and solver technology are changing the way we model these assembly structures. Today, continuous meshes are often replaced by individually meshed parts joined together by some type of connector or interaction definition. These individually meshed parts are typically joined together …
Throughout April and June 2016, MSC will be offering a series of free, hands-on workshops that will teach engineers how to simulate complex manufacturing processes such as forming, joining and welding. In addition to providing an overview of the use of finite element analysis (FEA) in various process simulations, these workshops will give you an opportunity …
At present, most companies use simple hand calculations or results from previous designs to predict loads. Neither of these methods is very accurate. Even small errors in calculating loads create large errors in stress results and very large errors in fatigue life predictions. Accurate loads can be determined by building and testing physical prototypes, but …
MBD software goes much further than kinematics tool by providing large displacement dynamics modeling capabilities that capture the full gamut of real-world complexity. MBD tools overcome the limitations of FEA by modeling rigid bodies, flexible bodies, springs, damper, joints and other mechanical components while substantially reducing the time required both to create and solve the …
