6 PRODUCT CATALOG Live Engineering: from networking & interdisciplinary topics to creative solutions. Our credo: Only those who understand will find solutions. We understand vibrations, therefor tectos should be your first point of contact when it comes to vibration optimization of drive shaft systems for vehicle prototypes and associated test beds. No matter whether they are motorcycles, passenger cars, commercial vehicles or industrial engines. tectos engineering means successfully working with the latest engineering knowhow and methods, the combination of various areas of expertise and many years of experience. So tectos supports customers to meet future market requirements better. How tectos solves your problem: Analysis Problem Definition Solution Multi-Body-Simulation Finite Element Method Simulink/MATLAB Simulation Testing Modalanalysis Operational Vibration Measurements Torsional Vibration Measurements Design Interpretation Planning Engineering Prototyping Production Development Functional Tests Basically: The earlier the vibration optimization takes place, the shorter overall development times. Early design, simulation, testing and measuring, even for elements of your test bed drive train, for example, will save you a significant amount of time. The resulting reduction of the number of required prototypes reduces costs significantly. In-house test beds increase the efficiency of customer projects and ensure the quality of our in-house developments.

7 ENGINEERING A view of everything: the big picture and the smallest detail. The portfolio of our engineering services gets constantly adapted to new market requirements we are often a few steps ahead. We are of course taking into consideration the growing demand for electric and hybrid drives. For such developments, the high speeds (well over rpm) and the different performance classes are two parameters that must be catered for the test bench. For example, tectos recently launched a modular e-engine test bench system covering power classes from to kw. The especially developed drive train enables speeds of over rpm. From development through simulation and optimization to on-site measurement, our experts have developed special tools that ensure troublefree testing. Our engineering specialists are your contacts for: Vibration control solutions Vibration optimization for vehicles Vibration optimization for test beds Torsional vibrations and shaft fractures Engine test beds Speed in excess of rpm Adapting to downsizing concepts Tuning the test bed to real vehicle behavior in connection with RDE

8 PRODUCT CATALOG tshaft SHAFT SELECTION AND VERIFICATION TOOL Description When a new engine is to be tested in a test bed, it is a particular challenge to select a drive shaft with the correct properties. It is important not only to transfer the corresponding torque, but also to take into consideration the stiffness and distribution of the inertia values. tshaft is a fast analysis tool which selects a drive shaft most suitable for a specific engine for a given test cell. All current engine types can be defined with just a few parameters. Integrated estimation algorithms are available for determining unknown quantities. The analysis is achieved with a non-linear torsional vibration calculation. tshaft uses a shaft database, which contains details of all tectos drive shafts (e.g. t, t, t and t series, CV-shafts in various sizes). It is easy to add new drive shaft information to this database. Features support of various engine types: in-line, V-type, boxer parameters which are not available estimation algorithms are provided modeling support for flywheels, dual-mass flywheels, clutches, quill shafts and transmissions administration of multiple test cells possibility to add user-defined drive shafts pre-selection of available drive shaft in a test field PDF reporting with torque and loss curves, for individual components calculator to evaluate inertia and stiffness from geometric data

10 PRODUCT CATALOG twrench BEARING MODELING TOOL Description twrench is used to create computation time efficient bearing models for finite element analysis, which are very efficient in terms of computation time. This is useful for cases where bearings should really be considered in an FE analysis, but where detailed modeling is not feasible. The models use simplified geometry for the inner and outer rings. The rolling elements are represented by non-linear springs. twrench requires radial and axial load displacement data input to adjust the spring stiffnesses to match the overall behavior of the bearing. Multiple standard bearing types can be modeled and stored in a library for further use. After creating the bearing models, they can be placed in an application model (e.g. a transmission housing), in order to simulate the overall behavior of the setup. This way, more precise results for stress and strain distribution can be produced than with an industry standard approach. The Hertzian surface pressure of the rolling elements can also be calculated in a post-processing step. twrench can be used to create models for the following bearing types: Tapered Roller Bearings Ball Bearings Angular Contact Ball Bearings Toroidial Roller Bearings Cylinder Roller Bearings Needle Bearings Axial Needle Bearings Features automatic FE model creation for multiple bearing types bearing stiffness adjustment placement in FE model flexible choice of bearing material modeling of dual-row bearings NVH support Hertzian surface pressure calculation for rolling elements additional modeling and placement of machine screws and bolts

16 PRODUCT CATALOG tpia SEPARATOR COUPLING Description New developments in engine and vehicle design often necessitate separation of the engine from the rest of the drive train; for example in the case of start/stop tests or emission control.

22 PRODUCT CATALOG t ELASTIC COUPLING Description The t is designed for test bed operation for passenger cars and light duty vehicles. This coupling is characterized by its low weight, high damping and low maintenance requirements. Naming The product is named according to the following convention: t -tttt-cccc-cvxx Example: t cv05 Operating Range Torque: Speed: up to Nm up to rpm joint size dynamic stiffness [Nm/rad] nominal torque [Nm] product name Benefits lightweight design low torsional stiffness high damping low maintenance Function As with all tectos drive shaft systems, the t follows a modular design principle, which separates the different functions. The elastic part of the drive shaft connection is used for torque transmission and to decouple and damp the torsional vibrations. The optimized shape leads to a precisely defined stress state under load. The inner ring is exactly positioned in relation to the outer ring because the bearing is inside the coupling. This means that only rotations are transmitted by the elastomer. The stable outer ring allows the elastomer to provide excellent support against centrifugal forces. The standard t specifications cover a nominal torque range of - Nm for a torsional stiffness of - Nm/rad.
