Design Analysis & Testing
Weston recognize that it is crucial to the success of our development programmes to eliminate technical risks at an early stage in the development cycle.

Prior to the finalization of our designs we use simulation tools and structure “Design Assurance Tests” to identify the performance that will be achieved. Included within this testing is specific reliability testing.

Mechanical Simulation
Finite Element Analysis (FEA) is a method of breaking down a structure into a number of parts or elements, for which exact results are available. The behaviour of the structure as a whole is found by the solution of simultaneous equations.

   
Finite Element Analysis  
FEA is normally performed using specialized computer software. Functionality includes automatic mesh generation techniques to define the type and layout of elements in defined sections.
FEA is carried out at the early stages of the design, in order to optimize product performance and to ensure structural integrity. Good design and careful material selection is necessary to deal with harsh aircraft engine environments.
Accuracy and rapid response to geometric change is achieved, due to the FE model’s association to the underlying 2D and 3D Computer Aided Design (CAD) geometry.
Simulation types include static, dynamic and thermal analyses, and Computational Fluid Dynamics (CFD).
The modal behaviour of parts is carefully monitored during analysis and testing to ensure dynamic interaction between the parts is avoided or controlled.
Analysis results allow fatigue, fracture and life predictions to be performed, as well as thermocouple thermal response evaluations.
Product and material physical test results are recorded and retained to improve simulation accuracy. Analysis results are often used to generate test levels and test conditions, and also to assist in the design of test hardware.
Correlation between analysis and test results is regularly performed to maintain accuracy.
