Subros Leverages Altair HyperWorks® to Build Optimized Product Designs While Reducing 60% Simulation Time and 40% Prototyping Costs

Jyoti CNC Automation Ltd. designs and manufactures a wide array of CNC Machines for metal cutting industries. They utilized Altair HyperMesh to optimize the existing design and improve static stiffness of their machines, and Altair HyperWorks to reach the optimized design and arrangement. Altair OptiStruct solver was then used to validate the effectiveness of the optimized product design. The result was an immense benefit in terms of resources and cost saved as mechanical accuracies were ensured right at the stage of the FEA software level, without having to create the physical prototype.

Urwahn Engineering GmbH is a startup in the biking sector. While bikes must meet many requirements to pass globally recognized test and load case scenarios according to DIN ISO 4210 safety standards, they must also be light to reduce raw material usage and create the best possible user experience. For this aim, simulation has always played a key role at Urwahn, a team that strives to maximize functionality and performance by using state-of-the-art tools. Under the Altair Startup program, Urwahn received access to Altair® Inspire™. To meet the DIN ISO 4210’s safety requirements, they simulated five load cases on the steel frame structure, studied the behavior of the single 3D-printed parts, and explored the impact of the material distribution on the overall system behavior. Inspire’s integrated topology optimization solver enabled Urwahn to push the material usage limit, reducing weight and costs while keeping stiffness and other boundary conditions on target.

Established in the early 1990s and headquartered in Gemlik, Borçelik is the highest quality galvanized steel producer, with the largest production capacity in Turkey. They are engaged in manufacturing hot dip galvanized steel, cold-rolled steel and hot-rolled (pickled and oiled) steel groups, all of which are industrial raw material inputs. Reducing emissions and fuel consumption drives the development of advanced materials and production processes in the automotive industry. Fuel efficiency relies on the successful design of vehicles and developing technologies that reduce the weight of vehicle body structure. There is always a need for research and development to maintain passenger safety while reducing the mass of the vehicle structure. A study was conducted to investigate the ductile fracture behavior of the high-strength galvanized flat steel that forms a vehicle body structure. To reduce the analysis calculation time, mass scaling was applied using the /DT/NODA/CST option which controls the nodal time step, and reduced the simulation time by nearly 50%. In terms of quality-related challenges, Borçelik saved nearly 10% of scrap material, and reduced costs by 5% after working with the design of experiments and applying numerical calculations through Altair simulation solutions.

An engineer working for Northrop Grumman Systems Corporation Marine Systems (NGSC-MS) was given a project to improve their teams’ current NASTRAN results post-processing workflow by writing a script to automate the task. They reached out to Altair for collaboration and Altair engineers were able to quickly determine that Altair’s mathematical modeling environment – “Altair Compose” – would be the ideal solution due to its ability to read, manipulate, and write NASTRAN results. Also, the Open Matrix Language is a scripting language that is familiar to the engineering community. Given sample NASTRAN results and requirements Altair engineers provided a “template” script. The NGSC-MS team was able to quickly understand and modify the script to their goals. The custom results were then viewable in HyperView as a contour plot, which saved a considerable amount of time during post-processing and documentation workflows.

With more than 35 years of experience in research & development projects INESPASA has been working with companies such as Airbus, Alestis, Boeing, and Renault. To be successful in a highly competitive market, aeronautical tooling companies like INESPASA must deliver maximum quality and comply with highly demanding standards and regulations while meeting tight time constraints and limited budgets. Developing and testing aircraft component prototypes is time consuming and expensive, so INESPASA had to find new and faster ways – like Multiphysics simulation – to evaluate its aero-structure designs, identify problems before they occur, and ensure viability. INESPASA turned to Altair and applied tools such as Altair SimSolid®, Altair® Inspire™ and Altair® MotionSolve®. Thanks to fast simulation results, INESPASA addressed their challenge and found the solution with the best weight-stiffness ratio providing optimum usability of their aero structure elements.

While rail is the most environmentally friendly means of transport, freight trains today do not look much different than those from the past. To reach the climate and energy targets of the European Union while achieving higher payloads and a better ROI, the railway sector needs an innovation boost to build more efficient and sustainable rail freight wagons. TransAnt GmbH, a joint venture with ÖBB Rail Cargo Group and voestalpine Steel Division, was established to bring more efficient and sustainable rail freight solutions to the market. With its innovative concept based on modularity and lightweight design, once operational the company seeks to revolutionize the market as a full supplier of freight wagons. The company used Altair® HyperWorks® for topology optimization – in particular Altair® HyperMesh® – to realize the transition to a weldable structure, Altair® HyperView® for pre- and post-processing, and Altair® OptiStruct® for FEA (including local buckling) and optimization.

Unmanned aerial systems (UAS) are a rapidly evolving technology and used for a variety of civil and military purposes. To ensure airworthiness, UAS manufacturers rely on advanced simulation and manufacturing techniques to create efficient designs. Aerial systems active throughout Europe and operating with diverse payloads for different missions require a reliable vehicle architecture and fuel supply. To ensure perfectly tuned architecture and a lightweight design while increasing stiffness and strength, Schiebel used Altair solutions in combination with 3D printing. The engineers performed various simulations to optimize the design of AM engine parts. Using Altair’s topology optimization structural design tool, Schiebel reduced the weight significantly while maintaining high stiffness. Subsequently, the system was evaluated by laminar and turbulent flow simulation as well as conjugate heat transfer simulation using Altair CFD™. Contacts, NLFE and complex dynamic systems were modeled with Altair® MotionView® and Altair® MotionSolve®. Schiebel also took advantage of APA solutions.

With Altair’s unique, flexible licensing model customers have access to these solutions at no additional costs. Altair Units allowed Ultimate to leverage APA products and access the functionalities of AlphaCell to predict the acoustic response of the bellow. Results included reduced run time, a decrease in model set up time, and increased combined metric correlation.

As the traditional optimization process at Renault required many iterations, simulation engineer involvement, and a considerable amount of time, the company was looking for tools and methods to improve this process. They wanted to implement a new, easy-to-use simulation tool that would allow non-experts, part-time analysts, and designers to gain insight and accurate results in early design phases of Renault chassis projects. With the goal to enable designers to run simulation by themselves without being dependent on the engineer’s calculations, the team began using Altair Inspire. The implementation on the Altair HPC platform enabled the engineers to send their highly complex calculations to the HPC server while running calculations on their workstation. The results included time savings, an 80% increase in process automation and mass reduction up to 20%.
