Welding Simulation to Optimise the Design and Development of Off Highway Construction Equipment

Understand the levels of accuracy that can be expected in a simulation with a view to establishing the state-of-the art in a commercial environment. Construction equipment is used in highly demanding structural applications across the globe for moving and removing materials from one place to another. The primary load bearing structures of these machines such as chassis’, loader arms and excavator ends are invariably arc-welded steel fabrications. Sheet steel is dominant but significant quantities of box sections and steel castings are also used. The use of arc-welded steel fabrications has proven itself durable in these highly loaded applications over many years and there is considerable qualitative experience in selecting the correct welding parameters. However, the process of designing fixtures, optimising welding parameters and validating them is a highly time-consuming iterative and expensive process. More recently, simulation tools have become available to help Design and Manufacturing Engineers optimise their design at an early stage in the process to reduce cost and time to market. Dr David Panni, JCB Group Structures Manager, outlines the historic processes for proving out fabrications and then provide case studies where up-front weld simulations have been successfully used to optimise weld parameters to reduce distortion and improve weld penetration while reducing the physical testing required.

Create Transformative Parts with an EDU nTop License

Have you ever thought about using data to control your geometry? What about light weighting your solid CAD models, or performing topology optimization that is 100% based on engineering principles and your specific parameters? If you answered ‘yes’ to any of these questions then you should be using nTop Platform, a unified design environment for creation, simulation, and advanced manufacturing processes. With nTop Platform you can easily design parts with graphs, surface-based or periodic lattices. You can create parts with variable wall thicknesses based on stress values or other data. You can design workflows that not only produce parts but also generate reporting to document your work. You can quickly iterate your design choices while reducing weight, cost, and time savings. This hour-long webinar covers nTop Platform’s: Implicit modelling Field-driven design Reusable (and reconfigurable) workflows EDU license program
