Mechanical engineering and plant construction

An activity frequently undertaken by medium-sized enterprises, mechanical engineering is a key industry among TECOSIM’s core markets. Companies in this high-tech sector are subject to price and innovation pressure in order to maintain and consolidate their strong position on the world’s markets. Environmental protection and resource conservation are also a main focus of their research and development.

Are you, as a machine and plant constructor, looking for a reliable development partner to assist you in finding fast, reliable solutions for your requirements? With the aid of computer-aided engineering (CAE), we calculate durability of assembly groups and components and their ability to withstand stress, thus prolonging their service life and ensuring problem-free operation. We will test your production systems under laboratory conditions and interpret findings. Perhaps you would like to optimise your production processes or find an intelligent solution for a new product. If so, we look forward to arranging a meeting with you.

TECOSIM offers comprehensive CAE development services to sub-sectors in the mechanical engineering and plant construction industry, such as those producing smelting and rolling mill equipment, thermal processing technology, foundry machinery, process engineering, fluid technology, precision tools, machine tools and mould construction. Our certified quality management system is the basis for planning and cost reliability and on-time delivery performance.

Our core expertise for mechanical engineering and plant construction

Structure simulation

Structure simulation evaluates the strength, stability and service life of components under mechanical or thermal boundary conditions, allowing precise analysis of stresses, for example, which can then be optimised in a targeted way.

Computational fluid dynamics

Numerical computational fluid dynamics (CFD) calculates phenomena which occur as gases and fluids flow over surfaces. Typical fields of application in mechanical engineering and plant construction include the mixing of fluids, torch optimisation, filling calculation, optimisation of reactors and optimisation of gear hydraulics.

NVH (Noise, Vibration, Harshness)

NVH stands for noise, vibration and harshness. NVH studies are able to provide essential services for mechanical engineering and plant construction, such as noise prevention and soundproofing.


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 mechanical engineering and plant construction include structural component optimisation, multi-physics problems and stability studies.

Multi-body system simulation

Multi-body system simulation is primarily used for rigid body calculation and kinematic simulation of articulated joints and drives of all types. 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

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.

Coupled or multi-physics simulation

Sometimes it is simply not sufficient 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.

Virtual benchmarking

Created by TECOSIM, the TEC|BENCH method not only allows industrial enterprises 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.
