Tailor-made vibration damping technology saving costs and increasing quality in mechanical engineering and testing applications

Summary

An Austrian SME developed a novel composite material (steel structure filled with special concrete) with excellent vibration damping properties. It is adjustable to individual client needs. For many new machining centers it significantly improved machining accuracy, enhanced tool life (up to 20% decrease in tool consumption), increased processing speeds (e.g. 20% reduced grinding times) and lowered noise emission. Partners for technical and research cooperations are sought.

The Austrian SME offers FEM (finite element method) analysis, design, engineering, fabrication and assembling of the system according to client requirements together with expertise and extensive experience in machine tool design and engineering in all areas of machine tools. 2) research cooperation partners: R&D organisations with the above mentioned research areas to enter into new R&D projects in the framework of funding programmes.

Description

In mechanical engineering applications (such as machine tools) vibrations have a detrimental impact on quality of products and tool life. Conventional solutions to reduce vibrations such as grey cast components are quite expensive and not individually adaptable for optimized vibration damping and client needs. The Austrian company developed a technology with excellent vibration damping characteristics to improve tool life, precision of mechanical operations, machine structure behaviour and sound emission levels significantly. The system consists of an innovative composite material, comprising a welded steel structure with high structural stiffness filled with special concrete. In comparison to grey cast components the new technology saves costs, especially for small batches and prototypes of machine tools, clamping plates etc. It also allows the integration of additional functionalities and components, such as heating or cooling coils, conduits for energy supply, hydraulics, pneumatics, anchors for lifting and many more. Compared to other composite material technologies (steel structure filled with polymer concrete) the novel system again has significantly better vibration damping behaviour and heat stability and does not contain epoxy resins (has less environmental impact). The special concrete can be adjusted to individual needs. Specific weight, damping characteristics, modulus of elasticity (E-modulus), compressive strength and other characteristics can be varied in a wide range to meet the particular client requirements. During engineering, the part's natural and resonance frequencies are determined and can be adjusted by design measures if they interfere with the overall structure or machine. Even possibly required vibration boundaries, such as vibration velocity and vibration amplitudes can be taken into account beforehand. The following types of the system are available and can be adjusted according to specific client requirements: - type 1: density up to 2,500 kg/m³; E-modulus up to 60,000 N/mm²; - type 2: density up to 1,200 kg/m³; E-modulus up to 12,000 N/mm²; - type 3: density 650 kg/m³; E-modulus approx. 5,000 N/mm²; especially suited for moving parts (slides, lathe slides, carriages etc.); - type 4: density 220 kg/m³; E-modulus approx. 100 N/mm²; especially suited for moving parts (slides, travelling columns etc.); Application areas: - The technology is currently in use in machine beds for machine-tools and machining centers (examples are turning, milling, grinding, lathing machine tools of all sizes). It is further applicable in structure parts, base frames and the like. - The system is also used in the testing industry, particularly in clamping plates, where it is engineered and designed for specific measurement tasks. Applications include testing of engines, transmissions, brakes, sound emissions etc. - The innovative compound material together with expertise in engineering and simulation are especially advantageous for developing prototypes of new machines. The SME is looking for: 1) technical cooperation partners: companies who want to optimize their new developments of machine tools, machining centers, industrial robots, industrial testing technology etc. by integrating the novel system for vibration damping. 2) research cooperation partners to enter into new R&D projects in the framework of funding programmes: R&D organisations with focus on thermal stability of machine tools and/or on the development/analysis of alternative filling compounds.

Advantages and innovations

1) excellent vibration damping characteristics: for machining centers this results in improved machining accuracy, enhanced tool life, higher processing speeds and lower noise emission levels. For example, grinding times were reduced by 20% while maintaining the same grinding results. In another project it was possible to decrease the tool consumption by 20%. 2) high temperature stability and heat capacity protecting the machine structure from thermal influences better than common materials and resulting in higher process reliability 3) flexibility in design: particular customer requirements such as certain characteristic shapes, integrated conduits for energy, hydraulics etc. can be considered. 4) no expensive moulds needed; the filled steel structure (a stay-in-place formwork as such) makes it very cost efficient especially for small batches or even prototypes. 5) via modern simulation software certain requirements (such as maximum vibration velocities for testing plates) can be taken into account in the early design phase; best quality results are guaranteed.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
