Advanced Manufacturing Capability

Technology Partner

Represented by Prof Graeme Oliver

Doctor of Technical Sciences in Mechanical Engineering (IFTR, Warsaw 2000)

Nkangala has established Advanced Manufacturing Technology Partnerships with our 50 year history as a local South African Mining Engineering Equipment Manufacturer. We ensure continuity and advancement in our engineering capability and competency though these strategic partnerships. 

Skills and Expertise- add tags blocks here

ABAQUS SIMULIA: A general purpose non-linear finite element analysis software for quasi-static structural, dynamic structural, transient thermal and coupled thermo-mechanical analyses. The software has additional capabilities but these are the areas we have the expertise in using the software.

TOSCA: An optimization package that can be used to control ABAQUS analyses to conduct geometric, material or another influential parameter optimisation

ANSYS Workbench: General finite element analysis package but chiefly used no for CFD analysis with ANSYS Fluent

SOLIDWORKS: Solid modelling /CAD software

CATIA: Solid modelling /CAD software

Accesses to Research Centres

Product Lifecycle Management Competency Center (PLMCC) – CPUT:

CPUT Aptronics AMTL: TIA funded advanced manufacturing laboratory to support industry and conduct research and development of products. Strengths are in mould making for composite materials and in designing modules and systems such as for the Coastal Observer instrumented buoy  and the Guardian AUV / drone.

Accesses to computing hardware

The PLMCC has a computing laboratory that is dedicated to CAD and is capable of doing the smaller size FE computations.

The AMTL has computational hardware capable of doing medium to large size computations.

The CSIR high performance computing centre could be utilized for very large computations by agreement and within the software licensing restrictions.

Finite Element Analysis In Mining Equipment

Static nonlinear contact finite element analysis or dynamic finite element analysis of structures to determine:

  • Stress ranges
  • Peak deflections
  • Contact gap openings
  • Bolt forces (including the effects of bolt preload and prying action)
  • Natural frequencies and mode shapes
  • Response to harmonic excitation

The above finite element results can be used to assess:

  • Design fatigue life
  • Sealing effectiveness of bolted joints
  • Effect of parameter and design variations
