Mechanical Engineering Analysis and Test

Focus on Fatigue

MoreVision has developed a number of programs to post-process finite element results, calculate fatigue damage and to plot damage directly onto the FE mesh. The assessments cover code of practices used in many countries (UK - BS7608, France -UIC 515-4 Goodman Diagram, German DIN 15 018, Swedish Volvo standards)
Experimental Methods

MoreVision strain gauge testing compliments its analysis services.
Software Success

MoreVision has sold its innovative engineering calculation software Research Engineers Inc. for worldwide distribution. The product has already earned MoreVision a DTI SMART award for innovation.
Composite Analysis

MoreVision has extensive experience in the modelling composite materials.
Dynamic Analysis
Avoid resonance by performing a dynamic analysis.
Plastic Analysis
What happens when stress rises above yield? - it may not be as severe a situation as you think.

Strain Gauge Testing

Strain Gauge Testing Compliments Our Analysis Services Perfectly
After manufacture test techniques can be used separately or in conjunction with finite element analysis. It is an essential tool for failure investigations or validation of design.

Equipment struck with a rubber hammer will vibrate at its natural frequencies. This response will be seen by the strain gauges and sensors. A spectrum analysis of the test signals will yield the frequencies associated with the natural modes of vibration. Damping characteristics can also be measured in this way.

The data acquisition equipment and computer can be installed at any location and is self powered. The photo opposite shows an installation in a railway vehicle. Testing does not necessarily mean that equipment needs to be taken out of service. 

After disappointing performance with commercially available bolt sensors MoreVision devised and produced special test bolts by introducing flats on the shank of the bolts and attaching standard linear gauges (photo on the left). The bolts were calibrated in a laboratory load cell shown in the photo on the right.

Bolted joint performance is a common source of problems for mechanical engineers testing a jointed assembly can help us understand poor joint performance. Preload in bolts can be measured using load cells or strain gauged bolts. It is possible to obtain a preload/torque diagram and joint relaxation over a given time period.

Once data has been gathered from test the process of analysis of test results and signal processing can begin. Read more.
Top Software Tools

MoreVision have some 20 years experience of problem solving with ANSYSŪ. They have developed a library of macros and software tools customizing ANSYS for specific problems.
Bolted Joint Analysis
MoreVision uses 'Boltcalc' software in conjunction with FEA for fast & accurate assessments.
Partnering Client Design Teams
Will it fall off? Is it strong enough? How long will it last? These are the questions on the minds of many designers. MoreVision can team up to perform simple strength assessments to allow designers to move forward with the confidence that their designs will ultimately satisfy structural criteria.
Independent Design Audits
A fresh pair of eyes can offer an new  insight into design critical problems.
Fixed Price Contracts
Whenever possible MoreVision offers fixed price contracts from the outset of a project.
Failure Investigations
Simply strengthening an area may not give you the results you want and could make the problem worse. Before a solution can even be considered it is imperative that the mechanics of the failure are completely understood.
