At Neorium Technology, we support model-based development using control technology and machine learning. This content introduces cases involving the construction of predictive models for nonlinear control targets using deep learning models such as "Transformer" and "LSTM," as well as high-precision image recognition (semantic segmentation). We can predict future behaviors of control targets with time delays and complex nonlinearities through time series learning, even handling phenomena that are difficult to model. Additionally, in image recognition, we accurately identify targets even in complex backgrounds using segmentation with Mask2Former, making it applicable in industrial and autonomous driving fields. We also support integration with control system design and experimental data analysis based on Python + TensorFlow and PyTorch.

This is a three-dimensional tire model that enables simulation evaluations of durability and ride comfort using a high-frequency short-wavelength nonlinear tire model by calculating the number of contacts between the road surface and the tire at 200 points. In recent years, there has been an increasing demand for driving simulators where the feeling, such as ride comfort, is important, and it also supports real-time applications. Case 1: Riding over a curb... Due to the 200-point multi-contact, it is possible to obtain results similar to actual behavior. Case 2: Vibration on uneven surfaces... It is possible to verify ride comfort considering the deformation of the tire rubber. Case 3: Low-speed steering behavior... It is possible to reproduce tire behavior at low speeds. Evaluation licenses are also available, so if you are interested, please contact us at the link below. https://www.neorium.co.jp/contact-us/

The document "Optimal Design of Composite Material Shells Using ANSYS and PSO" explains optimization methods using FEM and discrete PSO, as well as comparisons between analysis examples and discrete PSO and GA. In the design of composite material structures, there are challenges such as strong anisotropy in strength and stiffness, making numerical analysis like FEM essential. Additionally, design variables include not only the shape and dimensions of the product but also material specifications, necessitating simultaneous progress in structural and material design. Furthermore, material parameters, which are design variables, are often discrete values, making numerical handling difficult. In the typical design procedure for composite material structures, structural analysis is repeatedly conducted using FEM to evaluate the stiffness and buckling strength of the structure while determining the laminate configuration, during which some optimization method is applied. In this analysis case, when determining the laminate configuration of the composite material structure using FEM analysis, a discrete particle swarm optimization algorithm that can handle laminate orientation angles as discrete variables is applied as the optimization method. The aim is to compare the analysis results when applying a genetic algorithm and evaluate its superiority. For more details, please contact us or download the catalog.
