How can you master the turning point in the automotive sector?
With us, quite easily.

The auto­mo­tive industry is in a state of upheaval. The resulting chal­lenges are numerous. One answer is light­weight design, since making weight savings has a major impact on fuel consump­tion. This reduces fleet consump­tion and increases compet­i­tive­ness. More­over, this saving of resources also reduces the CO2 foot­print of each vehicle. This will make your target market happy. With us, you’ll realise light­weight design in the best possible way, because we have devel­oped inno­v­a­tive solu­tions for your chal­lenges.

Our solu­tion compe­ten­cies

Our formula for success in inspiring solu­tions is an expe­ri­enced team that develops and opti­mises compo­nents with passion and curiosity, using the latest design and simu­la­tion tools and methods.

Solu­tion 1:
We do light­weight design under cost pres­sure.

Thanks to our many years of exper­tise in light­weight design, we have a very high level of under­standing of how compo­nents or even entire systems can be made lighter with the help of compos­ites. Thanks to our expe­ri­ence from other indus­tries such as ship­building, wind energy and aero­space engi­neering, we can offer you solu­tions for a wide range of chal­lenges.

We support you throughout the entire real­i­sa­tion process – from concep­tual design, to simu­la­tion and opti­mi­sa­tion, to produc­tion plan­ning, while main­taining quality stan­dards.

This approach not only reduces your mate­rial and process costs, it also ensures the successful produc­tion of your light­weight compo­nents - in accor­dance with the quality require­ments.

Solu­tion 2:
We’ll find the last gram.

Thanks to our expe­ri­ence gained from over 150 light­weight design projects, we know how to find and exploit poten­tial for weight savings. For compo­nent opti­mi­sa­tion along the entire value chain, we use in-house, high-end simu­la­tion tools such as Ansys Mechan­ical & LS-DYNA or Altair Hyper­Mesh & OptiStruct. To achieve the best possible results, we not only apply our simu­la­tion exper­tise and leverage analysis automa­tion, we also develop our own calcu­la­tion tools to find the best solu­tion for you.

This is how we opti­mise your compo­nent in terms of weight, stiff­ness or strength, thereby making the desired resource savings possible while main­taining quality and reducing testing and produc­tion costs.

Solu­tion 3:
With us, it is really fast and safe.

In addi­tion to our many years of exper­tise in light­weight design and inno­v­a­tive compo­nent opti­mi­sa­tion, our profes­sional handling of your project makes an impor­tant contri­bu­tion to its quick and successful fulfill­ment. We achieve this by main­taining close and regular commu­ni­ca­tion with you in order to react quickly and flex­ibly to your wishes and offer solu­tions.

Speed and quality are also made possible by our 10-strong team, which is equipped with all the neces­sary in-house resources. We are constantly devel­oping – we do not just apply or imple­ment state-of-the-art digital engi­neering, we also further develop it, meaning that unique simulation/​calculation tools are avail­able. All of this leads to short devel­op­ment cycles and maximum compo­nent safety for you, while adhering to the budget frame­work defined by you.

  • Light­weight engi­neering in the auto­mo­tive sector

    Devel­op­ment of struc­tural assem­blies in premium off-road vehi­cles

    A German auto­mo­tive supplier for carbon compo­nents in the premium sector asked us to support them in the devel­op­ment of load-bearing fibre composite compo­nents in several areas of the vehicle. The goals were, among others, the mate­rial substi­tu­tion of previous compo­nent vari­ants made of aluminium, the suit­ability for large-scale produc­tion as well as to meet the highest demands in light­weight design. There were chal­lenging spec­i­fi­ca­tions with regard to weight, rigidity and safety against breakage, and the new solu­tion also had to be econom­ical.

    The following compe­tences at ar engi­neers led to success in this project:

    • Exten­sive explicit numer­ical simu­la­tions (crash and impact analysis/​HIC analysis).
    • Strength and stiff­ness analysis via static FEM calcu­la­tions
    • Para­metric lami­nate opti­mi­sa­tion for targeted mate­rial use
    • Accu­rate and high-quality docu­men­ta­tion stan­dard for submis­sion and presen­ta­tion to the client
    • Agile and high-frequency commu­ni­ca­tion with the customer to respond quickly to design and and require­ment updates as quickly as possible.

    We, at ar engi­neers, were able to achieve the successful mate­rial substi­tu­tion of several compo­nents by using the most modern design and calcu­la­tion tools and methods - while main­taining the required prop­er­ties and reducing the weight.

    Opti­mi­sa­tion of a CFRP rear wing for British sports car

    A premium carbon compo­nent manu­fac­turing and devel­op­ment company asked us to support them in the devel­op­ment of a light­weight rear wing for a British premium road vehicle. The aim was not only to ensure the exact dimen­sional accu­racy of the aero­dy­namic compo­nents so that a rele­vant contri­bu­tion to the overall perfor­mance could be achieved. Also, the weight require­ments were very high, so that extreme light­weight design with high corre­sponding stiff­ness and strength was neces­sary.

    The following compe­tences at ar engi­neers led to success in this project:

    • Very good under­standing of ultra-light­weight design with CFRP /​carbon compos­ites.
    • Eye on high stiff­ness require­ments for aero­dy­namic compo­nents.
    • Exper­tise in auto­mated numer­ical opti­mi­sa­tion with Ansys.
    • Auto­mated result eval­u­a­tion, in order to be able to respond quickly to changing require­ments from the customer.

    We at ar engi­neers were able to develop a CFRP rear wing that met the high require­ments thanks to our under­standing of ultra-light­weight design in combi­na­tion with the use of state-of-the-art tools and our flex­ible reac­tion to changing customer para­me­ters.

    Devel­op­ment and opti­mi­sa­tion of overall struc­ture for premium motor­bike

    A German motor­cycle manu­fac­turer contracted us to opti­mise struc­tural compo­nents for a road­ster bike. The aim was to achieve a weight saving of up to 40% without giving away more than 10% of stiff­ness compared to the welded steel struc­ture of the preceding design - without changing the manu­fac­turing process. In addi­tion, it was neces­sary to ensure economic serial produc­tion of these compo­nents

    The following compe­tences at ar engi­neers led to success in this project:

    • Topology opti­mi­sa­tion using advanced algo­rithms
    • Vali­da­tion of the opti­mised topology by means of FEM
    • Transfer of the results into econom­i­cally manu­fac­turable compo­nents

    Thanks to our exper­tise in topology opti­mi­sa­tion, the subse­quent vali­da­tion of the results and our expe­ri­ence in produc­tion plan­ning, we at ar engi­neers were able to develop a compo­nent that not only met all the para­me­ters, but could also be produced econom­i­cally.

    Devel­op­ment & Calcu­la­tion Engi­neer

    Cool that my compo­nent improves the driving plea­sure of a super sports car.

    Devel­oping the rear wing of a supercar was an exciting and chal­lenging task for me as I had lots of freedom to set up the complex devel­op­ment process: In the course of the project, I deter­mined the optimal layup of the fibre composite struc­ture in more than ten iter­a­tions.
