Guest Blog by Monash HPR: Optimising rocket motor bulkhead using Ansys Discovery Live

Monash HPR (High Powered Rocketry) is a student team dedicated to the design and construction of high-powered rockets to compete in the 10,000 ft and 30,000 ft categories of AURC. Read about how their use of Ansys simulation delivered 85-92% weight reduction during the design and optimisation of their rocket motor bulkheads.

Meshing Fabricated Structures in ANSYS Mechanical using Mesh Edit

The introduction of parallel part-by-part meshing to ANSYS Mechanical 15 back in 2013 was revolutionary. Structures which took hours to mesh now wrapped up in minutes, unfortunately removing one of our favourite excuses for taking a tactical nap. One of the limitations to this new feature was the fact that Multibody parts were still meshed…

Topological Optimisation with ANSYS 17.0

Utilising the new FREE topology optimisation ACT-extension, one can explore new innovative ways to reduce mass that were not available before. The DoE (Design of Experiments) approach may not be feasible if the design’s shape is not yet defined, while creating CAD models to capture all the potential design possibilities may be impossible. Now imagine starting with an arbitrary volume and…

Analysing Large Fabricated Structures

Meshed crane model

Cranes and lifting equipment pose a unique problem when considered in a finite element analysis. Their sheer size often prevents users from analysing these structures using regular solid elements. Instead, beam elements must be used to reduce the model to a manageable size. The problem with this approach, however, lies in the process of extracting…

Bulk Materials Handling & Heavy Lifting Equipment

Large scale reclaimer assembly which will be analysed using ANSYS

Designing equipment intended for use in the bulk material handling industry is no simple task. Engineers need to consider day to day operating conditions as well as unpredictable loadings such as user error/misuse and erratic weather conditions. Simulation software can optimise machine design and gives engineers the capability to decrease project budgets/timeframes and minimise the…

Analysing Composite Structures with ANSYS PrepPost

Material distribution from geometry thickness guide used with foam core

The design and construction of composite structures represents a powerful and lucrative industry that is predicted to grow dramatically as demand increases for the high strength, low weight properties possible with composite materials. Part of the ANSYS Workbench environment, ANSYS Composite PrepPost provides tailored tools for the multitude of composite specific problems that face designers…
