The development cycles of new products are getting shorter and shorter. At the same time, the requirements regarding weight, energy consumption, vibration behaviour and noise development are increasing. Modern simulation tools enable a targeted analysis of new and existing products without having to produce and test costly prototypes. This makes the development process shorter, more cost-effective and safer.

The IGMR has extensive experience in the simulation of mechanical and mechatronic systems. We would be happy to support you in simulating your product.

 


Multi-body simulation

Dynamik

Multi-body simulation is a simulation method for determining the dynamic behavior of complex vibrational mechanical systems. It enables the calculation of the system behavior in both the time and frequency domain. Beside movement of system components, many other sizes can be determined, e.g. forces and moments acting between bodies. Multi-body simulation programs such as SIMPACK, Adams or Simscape can be used to model complex systems quickly and efficiently. In addition, they can be coupled with other programs to include further effects or regulations.

The IGMR has many years of experience in modeling multi-body systems in various multi-body simulation programs. Multi-body simulation is used to analyze and improve the vibration behavior of machines, to calculate the loads acting on the system components or in conjunction with the finite element method to calculate component loads.

 


Finite element method

Finite-Elemente-Methode

The finite element method is a simulation method for the determination of deformation and stress states of complex geometric structures. The structures are divided into simple substructures, so-called finite elements. Depending on the application, the substructures are displayed with different standard element models (e.g. beams, bars, plates or shells). Any structures can be elastically modelled using this description.

At the IGMR, the finite element method is used both for supporting simulation in multi-body simulations and for strength calculations of components and assemblies. In addition, the IGMR has expertise in the stress analysis of sensitive structures such as high-precision material-locking joints.

 


Tolerance analysis

Toleranzanalyse

The optimal definition of tolerances for kinematic dimensions of mechanisms is a prerequisite for the proper functioning of these devices. Common CAD programs do not have suitable methods for determining the influence of design dimensions on motion errors (sensitivity analysis). There is also a lack of possibilities for precise prediction of the movement limits on the basis of given dimensions (tolerance analysis) or for optimum selection of the coarsest possible dimensions of the kinematic dimensions with adherence to small movement errors (tolerance synthesis).

The IGMR has been involved in solving tolerance problems for many years. For this purpose we have developed powerful programs for tolerance analysis. We would be pleased to support you with our experience and technical know-how in solving your tolerance problems.
