High-Performance Spring Components

The rough environmental conditions and loads are a real challenge for every component of the wave energy converter. We develop unique and high-performance solutions where technology standards are not sufficient. In this context, the NEMOS spring is developed as a high-tech component that allows efficient energy buffering and pre-tensioning. It is characterized by lightweight composite construction, capable of high torsion loads. The patent-pending NEMOS spring technology can be applied to different engineering applications, providing significant improvements in relation to weight and space compared with standard technologies.

 

NEMOS Spring Applications

Flex Shaft

The capability to combine high torsion loads with superior flexibility matches the NEMOS spring technology perfectly with flex shaft applications. Compared with state-of-the-art carbon flex shafts, the NEMOS spring technology is capable to reduce the amount of material required significantly and therefore the weight per meter.

Torsion bar

The NEMOS spring allows efficient energy buffering and pre-tensioning. Here, it is especially suited to be applied as a torsion bar. Compared with available products, the NEMOS spring requires half of the space and also significantly reduces the weight of the component up to 75 %.

Coil Spring

The unique multilayer design of the NEMOS spring applied to a coil spring geometry enables the design of significantly lighter springs than standard products. Especially for high-load or high-performance applications, weight savings up to 50 % are a game-changer.

Testing and monitoring

The NEMOS Spring is developed with modern product development technologies. Based on a detailed mathematical model, the geometry is designed with CAE-Tools including computer-aided design and finite element analysis methods. Comprehensive quality assurance like non-destructive testing with CT-scanning is supporting the manufacturing process. Extensive testing of the part and material behavior are then used to guaranty part properties within the specification.
