Analysis of train equipment box vibrations and other related vibrations! Examples of current evaluations conducted.
We would like to introduce examples of our CAE analysis services. At Contract Level 2 (Analysis ⇒ Cost Reduction, VA Proposals), we conduct vibration analysis of train equipment boxes using the analysis software "Optistruct," which includes current evaluations, cost reduction considerations, and actual machine test evaluations, as well as high-difficulty roof crush strength analysis using "LS-Dyna." The inputs include current CAD data and cost reduction targets, while the outputs consist of analysis result reports and cost reduction consideration materials. 【Case Overview (Partial)】 <Roof Crush Strength Analysis> ■ Analysis Software: LS-Dyna ■ Details - Current Evaluation - Consideration of Countermeasures: Component Arrangement, Manufacturability, Material Availability, Large Deformation Elastic-Plastic Analysis, and Contact Considerations, resulting in high analysis difficulty. *For more details, please refer to the PDF document or feel free to contact us.
