Development and Optimization – Manufacturers Rely on ContiTech

It is not just in the product area that manufactures count on the experience, competence and quality of ContiTech Vibration Control. With highly modern processes, ContiTech engineers complement new developments or optimize existing systems. In this way they help improve vibrational performance and extend service life. Whether industrial vehicles or systems like thermal power stations or wind turbines are involved – ContiTech helps out with the following processes:

Calculating service life: To prevent an elastomer component from failing unexpectedly, ContiTech makes use of the latest computer methods for calculating the life cycles of rubber-to-metal products. With the help of the finite element method, load scenarios are simulated on a 3D model. In this way, relief can be calculated on the computer for critical points – i.e. spots subject to excessive stress. The resulting diagram illustrates the time history of highly true-to-life product stressing through to the point of failure. The upshot: Product quality is improved and development accelerated.

Multi-body simulation: Whether a new development or an existing system is at stake, ContiTech calculates the best possible mount and its optimum positioning. On the basis of data for mass, momentum of inertia, mounting points and stiffness, reliable statements can be made on: performance when empty, acceleration at comfort-relevant points, mount positioning, vibration decoupling, maximum bearing load and any hydraulic damping as may be needed. Special software tools tailored to the specific application make all this possible.

Mobile measuring technology: The actual vibration performance of industrial vehicles occasionally differs from what was calculated in the development phase. ContiTech’s mobile measuring service allows manufacturers to check the vibration behavior of their vehicle under real-life conditions – directly on the test course. The results are immediately evaluated by ContiTech engineers and improvement suggestions made.

New Bell Mount Suspends Hanging Loads of Up to 300 Kilos

Application possibilities

With the new SCHWINGMETALL® bell mount for suspension of hanging objects, ContiTech is expanding its range of products. The new SCHWINGMETALL® bell mount comes in three types for weights from 150 to 300 kilos. The new product offers many application options for suspending objects at low frequencies. The ceiling of a sound studio, for instance, can be suspended with one of the new bell mount and thus perfectly insulated. This prevents undesired vibrations from negatively affecting recording work. Heavy pipelines or cable ducts are still another application area. Suspending these by means of ContiTech bell mounts guarantees a building the requisite protection.

Technical specifications

The inherent frequency of the new SCHWINGMETALL® bell mount is particularly low. This means that the product provides excellent insulation even from low excitation frequencies. The rubber-metal component is completely galvanized and has a metallic rebound buffer. Kindly refer to the data sheet for further specifics on the individual types, i.e. spring stiffness, maximum load, mass, and elastomer hardness. The data sheet can be downloaded: here (1,06 MB)

Mounting Tomorrow's Engines with ContiTech

More stringent exhaust gas standards saddle construction machine manufacturers with extra duties as of 2011. Stage IIIB of directive 97/68/EC and Tier 4 exhaust gas legislation in the US regulate emissions levels for construction vehicles like excavators, wheel loaders and rollers. The laws establish new requirements for engines and engine mounts.

Exhaust gas aftertreatment makes power units more complex and heavier. The tougher combustion process increases vibrations and makes for more noise. This ups the demand for vibration isolation and noise reduction. The suspension and bearing components are thus forced to satisfy new standards.

There is an extensive standard range of products available for this purpose under the known SCHWINGMETALL® and MEGI® brand names, including:

  • SCHWINGMETALL® Series C dome mounts and MEGI® bearings with good rebound characteristics for suspending engines.
  • SCHWINGMETALL® hydromounts dampen impact loads and insulate vibrations. They are available as hydrobushings and in other forms.
  • Mounts with switchable options: These ContiTech mounts have each been optimized for at least two engine load ranges. Riding comfort and driving dynamics can be enhanced by altering the stiffness or varying damping.
  • Absorber: Passive absorbers can be used to achieve a targeted reduction in undesirable frequencies and are manufactured individually – for use in optimizing existing applications as well.
  • Active absorbers are the vibration isolation technology of the future. The system developed by ContiTech automatically reduces targeted drive vibrations by generating counter-vibrations – over a broad frequency range and also in the case of fluctuating excitation vibrations.

ContiTech offers diverse solutions – and the right answer to every type of vibration. Read more about them a www.schwingmetall.de and www.contitech-megi.de.
