CFD Analysis of CRRC's LACMTA Heavy-Rail Rapid Transient Vehicle

This has been an on-going project for our CFD consulting services team during most of 2018. As we all know, there is nothing like a “site visit” to meet your fellow engineers and see hardware. In early September, Drs. Laird and Hearn visited the CRRC Changchun Railway Vehicles Co., Ltd in Changchun, China. This is a cooperative project where Predictive has partnered with Hengstar Technology, Shanghai, China (Dr. Lu Hongsheng is shown on the left of our group photo). The project work requires a complete flow and thermal analysis of Los Angeles County Metropolitan Transportation Authority (LACMTA) new passenger transit vehicle. The CFD requirements are a notch above normal specifications with tight controls on air flow volume, maximum velocity and distribution. Thermal analysis looks at vehicle cool down on hot days (transient thermal with solar radiation and lots of internal heat generation) and also thermal management within the electronics and motor drive bay at bogie level.  All simulation work will be validated against vehicle mock-ups.

Our next FEMAP training is Oct. 22-26, 2018

As our longtime customers know, our FEMAP training was created by us from the ground-up from our work here at Predictive Engineering. We've successfully completed more than 800 projects and our ability to teach FEA & FEMAP comes directly from those diverse projects.

Over the years we’ve provided direct and customized training for a diverse swath of engineering specialties, who challenge us with their unique questions, models & scenarios. We welcome that challenge and if you're ready to turbo-boost your skills, we look forward to having your team join our next training the week of Oct. 22-26, 2018 in ever-sunny Portland, Oregon.

China News - LS-DYNA Implicit Class

LS-DYNA is historically known as the world's best explicit analysis code or the leader in the finite element analysis of nonlinear transient events. During the last ten years, LSTC (the manufacturer of LS-DYNA) has heavily invested in the development of its implicit anlaysis capabilities. Today, LS-DYNA can seamlessly handle complex, nonlinear analyses from static (implicit) to transient (explicit). Predictive Engineering has developed training course materials that covers both the implicit and explicit sides of the code. It was with pleasure that we taught a course in Shanghai, China to 27 students from industry and academia. This three day LS-DYNA training course was focused on LS-DYNA's implicit analysis capabilities from linear, elastic static stress analysis to static nonlinear analysis to fully, transient nonlinear analysis. The course finished with a half-day training on the linear dynamics capabilites of LS-DYNA.
