Are you, as a construction or agricultural machinery manufacturer, looking for a partner in numerical analysis and simulation? TECOSIM has more than 20 years’ experience in computer-aided engineering (CAE) and develops solutions for lightweight design and an increase in energy efficiency, reliability and durability. We offer a comprehensive range of CAE services throughout the course of your product development.
Structure simulation evaluates the strength, stability and service life of components under mechanical or thermal boundary conditions, thus allowing precise analysis of stresses, for example, which can then be optimised in a targeted way. Typical uses in construction and agricultural machinery include structural strength and crash simulations for driver’s cabs and structural component optimisation aimed at reducing weight or increasing service life.

Numerical computational fluid dynamics (CFD) calculates phenomena which occur as gases and fluids flow over surfaces. Uses in construction and agricultural machinery include powertrain optimisation (elbows, exhaust, air filters), optimisation of gear hydraulics, optimisation of hydraulics for drives and equipment assemblies and compression simulation.

NVH stands for noise, vibration and harshness. NVH studies can be used to enhance noise prevention and soundproofing in construction and agricultural machines.

The use of different mathematical calculation methods identifies optimisation potential for individual components or component groups regarding their weight or mechanical properties. Analysis results are incorporated into the development process once or as part of a continuous improvement process. Typical uses in construction and agricultural machinery include structural component optimisation, multi-physics problems and stability studies.

Multi-body system simulation is primarily used for rigid body calculation for powertrains and chassis components as well as kinematic simulation of articulated joints and drives. The calculation speed of multi-body system simulation enables complex modules such as entire assemblies to be easily mapped and integrated into control circuits.

System simulation is used to examine highly complex overall systems in which many sub-systems interact. Mapping and simulating such a system is a supreme discipline: the physical properties of all components and sub-systems which are interconnected with each other and exert influence on one another must be described in a mathematically correct way and their behaviour evaluated. It is essential not to lose sight of the overall system as a sum of all parts for all details. TECOSIM has specialised in 1D simulation.

Sometimes it is simply not enough to examine the physical properties of components in isolation. Whenever several physical phenomena are simulated regarding their interaction with one another, this is referred to as multi-physics simulation. Findings established in this way often present a truer picture than separate studies of individual phenomena. Multi-physics simulations play an increasingly important role in all stages of a product’s life cycle, from the analysis of new material properties, their mapping in virtual material models and parameters, through to production process simulation and calculation of product resistance under the effect of flow. .

Created by TECOSIM, the TEC|BENCH method not only allows construction and agricultural machinery manufacturers to improve their own products through comparison with competitors, but also optimise quality during production. Typical uses entail checking of manufacturing tolerances or deviations between a design and the manufactured component.
