Body Engineering of Karsan Taxi

Earlier this year, Light Black Design were contracted by Hexagon Studio to do the full Body Engineering of the critical sections for the exterior panels of their Taxi Project, intended for worldwide production in 2012.

As we posted in January, this project was intended as a replacement for the NY Cabs. Whilst it is unfortunate that they were beaten at the final-post by Nissan, Hexagon Studio (and their parent company Karsan) took note of all the positive support for their taxi, and made a very quick decision to produce the vehicle for a range of alternative customers.

Whilst the specific details of this project are confidential at this point in time, what we can say is that the first stage of the project for Light Black Design involved working closely with the Hexagon Studio's principal engineers, designers and manufacturers, where we were able to offer our vast knowledge of working with a large range of lightweight materials, to help their engineers select the most appropriate materials and processing methods for the Exterior Panels of the vehicle.

Following this initial investigation we have been busy generating extremely detailed documents that will form the principal guidelines for our clients engineers to fully define all the exterior panels and the associated fixing methodology to fit the panels to the BIW (Body in White).

Alongside this engineering ssection of the project, we have also written a selection of  "How to..." guides which will give all their engineers a range of handbooks that will enable them all to design and engineer theses type of panel in the future, in materials that they might not have traditionally used in the past.

All this work is being done both in 2D and 3D formats, using Catia V5

How we use Catia V5 in the office

Once again, the automotive design offices are in a extremely privileged position to have the most advanced 3D CAD systems as standard. Whilst there are a number to choose from, throughout the majority of the 14 years I was lucky enough to be in various offices like McLaren Automotive, Caparo and Gordon Murray Design we all used Dassault Systemes CATIA.

Although the initial investment is often hard to justify, I 100% believe that if the software is used properly and used in as many of the design stages as possible (i.e. from initial concepts right through to even the hydrodynamics of a yacht) the costs can be justified.

Whilst it is easy for me to say that it can be used efficiently, after 14 years sitting behind my CAD screen, it is a daunting task taking on a new design tool such as this, and the hard bit starts right from the start when you try and decide which of the many options you want/need. In the marine markets these generally range from styling tools, naval architecture, general 3D CAD right through to the composite FEA software. And of course, if you have the budget, these options could end up costing a frightening amount of money. But in most offices, the users just need some surfacing and then some solid generating tools, together with the standard 2D packages. And in fact its not until you need to generate A-Class surfaces (exterior panels) for cars that you need all the top level surfacing tools, particularly if you are importing your hull and foil shapes from other software.

To cut a long story short, I believe that having a tool such as Catia will help everyone in a design office. And due to the fact that the design process withing Catia is all parametric, if you need to go back and change anything it is easy. This makes it significantly faster to create not only the first parts but also the next parts if they are similar. It allows all the designers and engineers to see what everyone else is doing in the office as you can generate large assemblies on your screen and hence reduces errors. It will help to manage to the design process from start to finish, with its data management software called SmarTeam. This allows the engineers to do the design work, send it to the line managers for sign off, and then allows the rest of the office (purchasing, manufacturing etc) to see and download the relevant information.

To get over the first hurdle of trying to choose what I needed, I worked very closely with a company called Intrinsys www.Intrinsys.co.uk, in the UK. They are one of the companies that sell CATIA, and are the people you should go to if you are connected to the marine business. The main reason I chose to buy from them is that having worked with them when I was at Caparo, where they supported us in setting up our own unique solutions to how we wanted the design office to work, I know that whilst they are "salesmen" for CATIA, whats more important is that they are first and foremost, users of the software, and in fact the majority of their engineers on site are working on internal projects designing advanced automotive components for internal and external projects. This is vital when wandering down a "new path" as they were able to give me honest answers and will always be there on the end of the phone if it doesn't all go quite how I was hoping it might...! And for those of you thinking that your office just cannot justify this sort of software, then give them a call and I am sure you will be surprised just how much it might cost.....

So now I am in a position to be able to offer some help or design work to any of the design offices out there who are looking into using this type of software, or who have already chosen it but need more parts designed and engineered.
