Latest news from DC White Consulting Engineers

A very warm welcome to our Spring newsletter. We are freshly returned from two exhibitions, where we were excited to show the new Recovib Tiny wireless vibration recorders to the engineering community. 



See below our stand at the Southern Manufacturing & Electronics Show at the end of March. We had a great deal of interest in the Tiny, with many people attracted by the model car: this was to simulate the capabilities of the miniature vibration recorder on a full size vehicle.



Recovib Tiny at Southern Manufacturing 



There's more information on the Recovib Tiny below, including a new video case study, plus a look at the other industrial accelerometers in the range.

In addition, this month we also take a look at a recent case study showing what we can do in design optimisation. in this instance for a cafeteria stool!

As ever, your comments are welcomed on anything you read here, or if we can help with any of your engineering queries.



Happy reading,



The DC White team

New case study: The Tria-axial  Recovib Tiny



The revolutionary miniature wireless vibration recorder

Here is the latest video case study from Micromega: New Tiny Video Case Study. In this video we demonstrate NVH validation (Noise Vibration and Harshness) for an automotive parts manufacturer. Using two Recovib Tiny's attached to the underside of the vehicle, the video demonstrates the ease and speed of analysis enabled with the Tiny's unique features.

New Design Optimisation case study

Cafeteria Seating gets a Ruggedized Re-design
When a market leader in educational seating approached us to assess proposed design developments and optimise the design of one of their ABS plastic products, we needed to apply some lateral thinking. The ABS plastic seats were cracking around the mounting post and concern was raised as to whether different methodologies for attaching the seats to the metal posts was causing the cracking, or increasing the likelihood of a crack occurring.

There is a saying that you should "never under-estimate the ingenuity of stupidity", but when designing for the education market we needed to think more along the lines of "never under-estimate the ingenuity of abuse a youngster can apply to your design". Our starting point was to look at the range of sizes and weights of users, as teachers may use the seats as well as students. We then considered what a 'reasonable level of abuse' was to apply to the seat surface and decided that a person standing on the edge of the seat was a foreseeable event.
Using finite element analysis software we prepared computer models of three seat designs supplied by the client and evaluated the resulting stress plots to determine percentage improvement in the different design stages. Their second developmental design was 14% stronger than their initial design. 

However we then optimised that design which allowed us to minimise the amount of additional material required and also reduced the modifications needed to the seat moulds. It was 36% stronger than the client's second design and 55% stronger than the initial design, which in real terms means it would need a person weighing 232Kg sitting on our design to break it. 

Different methods of seat attachment are used in the USA and Europe, but we were able to show that these did not cause the cracking. We were able to prove that in the USA, they were applying almost 100 times the necessary cracking force into the seat attachment bolt.
The client was very happy with the suggestions contained within our report and has requested design optimisation of more of their products.

New wired accelerometers

DC White CE exclusive UK distributors

We are delighted to bring the Micromega range of industrial accelerometers to the UK market. 

Recovib Tiny at Southern Manufacturing 

The key benefits of the new IAC range are:

- Bridge the gap between the performance of laboratory accelerometers (which are often expensive, fragile and offer low protection) and the robustness of industrial accelerometers (which are sometimes cheaper but often noisy and inaccurate).

- Can be deployed in industrial environments for monitoring machinery or structures.

- Widely used in a variety of fields, such as the machine tools, precision machining and on-shore and off-shore wind energy sectors in monitoring or active vibration control applications.
