Lightweighting

Lightweighting

Applying simulation upfront in the product development process means you can meet your performance targets by designing lightweight earlier instead of working to take mass out later. We develop and implement intelligent simulation technologies that allow you to find the optimal balance between weight, performance, and cost for your products. Altair accelerates your lightweighting initiatives with topology optimization, advanced materials, and pioneering innovation.

Topology Optimization

Topology optimization develops optimized structures by considering design parameters like expected loads, available design space, material, and cost. Embedded early, it enables the creation of designs with minimal mass and maximal stiffness. For more than two decades, Altair OptiStruct™ is the original topology optimization structural design tool and has driven the design of products you see and use every day.

  • Right the First Time: Create optimal designs early and reduce costs associated with design failure.
  • Exceed Performance Targets: Maximize performance by starting with part and assembly designs that withstand all real-world conditions and loads.
  • Design for Manufacturability: Find the best material distribution for your traditional or advanced manufacturing process and compare designs.

Altair Inspire™ brings OptiStruct® into a new user experience encouraging earlier application of topology optimization. Both tools consider multiple manufacturing constraints, including symmetry patterns, draw direction, cavity avoidance, overhand angles, and extrusion. Topology optimization allows for fast design exploration, improved development productivity, and identifies opportunities for part consolidation.

Advanced Materials

Altair provides comprehensive tools to design, optimize, and analyze parts and assemblies manufactured with laminate, chopped fiber, and particulate composites. OptiStruct is widely used for the design and optimization of laminate composites. It delivers optimal ply shapes, number of plies, and stacking sequence, while observing manufacturing constraints. Altair Multiscale Designer™ provides accurate and efficient simulation of materials and parts manufactured with continuous and chopped fibers, honeycomb cores, lattice structures, and more.

Generating and evaluating a finite-element analysis (FEA) model with composites adds another dimension to the pre- and post-processing requirements. The next generation of HyperWorks generates laminate definitions efficiently and visualizes the stacking sequence, ply orientation, and draping angle deviations on the FEA model. It maps geometry ply shapes to element sets and performs sophisticated post-processing at the laminate or ply level.

Composite material analysis can be carried out in OptiStruct for linear and non-linear structural problems under static, dynamic, and thermal loadings, and Altair Radioss™ for highly non-linear problems under dynamic loading. Altair tools model delamination, crack propagation, and fiber and matrix failure under real-world conditions. Without physical testing teams can assess the stiffness, strength, durability, and stability of a structure, in addition to understanding the impact performance of composite designs.

Pioneering Innovation

The Altair product engineering services team works across industries in order to use processes and techniques from one industry and apply them to another. We've taken composite design techniques from the aerospace industry and applied them to passenger cars, and optimization processes from automotive and applied them to consumer goods. Our team creates industry-leading optimization solutions with our product development consultants to deliver the best possible technology application that other companies cannot match.

The team uses the latest optimization techniques and processes to deliver innovative solutions for our clients' product weight, performance, and cost challenges. In the traditional design process, simulation technology is used as a verification tool, and results can be delivered too late to impact the design direction. We believe in a different approach - CAD and CAE are deployed in parallel.

The concept phase of product development often fails to deliver mature engineering data to support the program business case, often resulting in costs to correct issues. Altair's process is used to rapidly interrogate design alternatives in the early development stage to help eliminate the risk of using immature concept deliverables and potential downstream issues in product development.

Automotive’s Only Award Dedicated to Vehicle Lightweighting

We have a deep commitment to vehicle efficiency, so much so that we have established the automotive industry’s only award dedicated to vehicle lightweighting. The Altair Enlighten Award honors the greatest achievements in vehicle weight savings each year. It inspires interest from business leaders, engineers, policymakers, educators, students and the public, stirring competition for new ideas and providing an incentive to share advances.
