Stress Analysis of Loading Shovel Bucket
The bucket of a loading shovel was analyzed by the finite element method. The purpose of the analysis was to compare the stress distribution across the bucket with specific location where cracks had been found during maintenance inspections. The analysis confirmed that these locations were subjected to high stress concentration and were prone to failure in perfect agreement with field observations. The study also allowed to make recommendations for a replacement material with a higher yield strength in order to prevent these cracks from reoccurring in the future.
Design and Analysis of a Double Deck Screen – Conveyor Support Structure
A finite element analysis of a conveyor support structure (7.5m x 3m x 10.5m) to be used in an open pit mine application was undertaken by ARES. This project involved using standard structure codes for performing static and dynamic analysis. The structure is currently in service.
Dynamics Analysis of Multi-DOF Systems – Modelling and Optimization
ARES has developed customised MATLAB® based software for the analysis of passive isolation systems. Some of the capabilities of this analysis tool include the computation of natural frequencies, mode shapes, transmissibility plots and steady state solutions. This tool can deal with varying boundary conditions and coupled dynamic constraints. An optimization module is included as well.
Structural Control Simulation using Feed-Forward Control – Uncontrolled and Controlled Response – Simulation and Control Development
ARES is currently experimenting with Magneto-Rheological (MR) fluids for the active control of structures. The aim of this project is to enhance fatigue life of damaged structures by using semi-active control algorithms. This project is currently in an experimental phase.
Rigid Body Dynamics – Simulation and Analysis
ARES has developed customized tools for the analysis and modelling of dynamic systems exhibiting rigid body behavior. These tools have been used in the analysis of the rigid body dynamics of bicycle and motorcycle frames. Work is currently in progress to expand the capabilities of these tools in order to handle flexible structures.
Design of Experiments – Response Surface Modelling
ARES has experience in the use of Response Surface Methodologies (RSM) for building meta-models for dynamic systems. Design of Experiments (DOE) has been used for building these meta-models. Our experience includes the use of DOE and statistical analysis for structural testing.
ARES has developed computer codes based on state-of-the-art simulation and optimization techniques to compute reliability indexes. Some of the techniques used include: First Order Reliability Methods (FORM), Low Discrepancy and Adaptive Importance Sampling. FORM methods are known to be more efficient than the traditional optimization techniques. Importance and Low Discrepancy Sampling techniques alter the probability density function in order to reduce the number of response evaluations needed to evaluate the reliability index.
3D Pose Estimation
ARES has developed proprietary algorithms to determine the location (position and orientation) of a rigid body in 3D space from a number of range measurements (trilateration problem). A post-processing module allows performing uncertainty analyses on the resulting poses.
Verification for buckling of support columns used during assembly of water tanks (Tank Nominal Capacity = 5655 m3): An analytical evaluation of the carrying capacity of the columns used for the assembly of large capacity water tanks was conducted in order to assess the impact of the modification to their original length. The columns were verified for buckling following the recommendations of AISC in the document ANSI/AISC 360-05 – Specifications for Structural Steel Buildings.
Design of steel ring for reinforcement of HDPE cap for protection of threaded end of oil pipes during transportation: A steel ring was designed to increase the impact strength of a HDPE protector used to guard the threaded end of oil pipes against accidental impacts during transportation and absorb 1200 J during impact tests.
