Alstom

Alstom coupled topology optimization with additive manufacturing to explore the feasibility of alternate manufacturing to traditional casting. This resulted in a 70% weight reduction of its locomotive component.

Using Topology Optimization with solidThinking Inspire for Improved Casted Rail Compoments

A simulation driven approach was taken using solidThinking Inspire for topology optimization, Evolve for shape refinements and HyperWorks for FE analysis for the optimization of an existing component design to be manufactured with casting/AM technologies

Sharma & Associates

Sharma & Associates (SA), a Chicago-based consulting firm that is focused on providing engineering solutions to the railroad industry, led the effort. Since 1995, SA have delivered safe, effective and efficient solutions to its customers, which include the Federal Railroad Administration (FRA), the Association of American Railroads (AAR), railroads and transit agencies, rail car builders and rail car component manufacturers. The objective of the Altair ProductDesign team effort was to develop an ‘Engineer Protection System (EPS)’ that can protect train crew in frontal collisions (a common mode of train collision) from secondary impact injuries.

Optimal Design Exploration Using Global Response Surface Method: Rail Crush

As design exploration and optimization methods have become commonly accepted across a range of industries, such as aerospace,
automotive or oil and gas, they are frequently utilized as standard practice to efficiently produce designs and aid critical engineering decisions. The widespread acceptance of these methods coupled with the power of modern computing has led to applications across a range of design problems and ever-increasing complexity. The size and scope of this expansion continually pushes the boundaries of existing exploration and optimization methods. Furthermore, a complete exploration of the optimal design space includes computationally intensive features such as multi-objective optimization, to understand the trade-off between competing objectives, and global optimization, to avoid local extrema.


Railcar Manufacturer Speeds Design Modifications with HyperWorks

American Railcar Industries, headquartered
in St. Charles, Mo., designs and manufactures
commercial railroad cars, producing
every part of the car above the wheels.
Customers use the company’s railcars to
transport all sorts of liquid and solid raw
materials, including oil, coal, cement, sand,
grain and other substances. Their designs
include boxcars, gondolas and hoppers,
among other styles.

Nippon Sharyo Uses AcuSolve Simulation to Make Japan’s Bullet Trains Safer, More Comfortable



HyperWorks Accelerates Design Process and Development of Diesel Export Locomotive at RDSO

Altair HyperWorks helped RDSO reduce development time and optimize structural characteristics of the diesel export locomotive. Physical testing on these large, complex structures had to be limited. Using HyperMesh/HyperView pre/post processing capabilities, RDSO were able to simulate design and verify that engineering specifications are being met and help validate the final design.
