Multi-body Dynamics simulation

Analysis of mechanisms and moving bodies using ADAMS

TRaC engineers have simulated some of the most complex Multi-body dynamic scenarios. Analysis to determine stresses and deflections under dynamic loads is inevitably present many problems to overcome; the more so when dealing with mechanisms whose infinitely varying configurations make it impossible to choose a 'worst case' geometry for study. Complexities are compounded when variations in form are coupled to time varying accelerations or shocks that modify inertial loads. Similarly, vehicles travelling over rough surfaces involve interactions between relatively stiff structures whilst having comparatively flexible suspension and tyres with the terrain profile. ADAMS is the leading edge simulation package which TRaC uses to solve such problems, predicting motions in the analysis of the complex behaviour of mechanical assemblies. Using this tool, engineers evaluate virtual prototypes and optimise designs for performance, safety and comfort, without the inevitable time-scale and cost risks in building and testing physical prototypes.

TRaC are experts in Structural analysis across a wide range of industries

The effective use of powerful tools demands the highest engineering skills; the clear insight into critical design features and the experience to translate this knowledge into an idealisation that simulates reality.

At TRaC we combine that know-how and ability to provide engineering predictions for products under development, ensuring design success and protecting vital project deadlines. The consistent attainment of these goals sets TRaC apart from its competitors.

ADAMS offers more than just dynamic analysis; functionality subroutines allow mechanisms and vehicles to be operated by mimicking onboard systems that for example pressurise hydraulic circuits, apply drive torques, control steering, etc.

In many cases boundary conditions can be uncertain. Uniquely, TRaC's analysts perform on-site data acquisition to measure real world inputs, translating them into regimes for either analysis or laboratory test purposes.

Projects undertaken include:

  • Understanding the strength and durability of battlefield vehicles and the equipment carried.
  • Predicting the effect of vibration and shock isolation for the crew of land, sea and air vehicles to ensure comfort during operation.
  • Fork Lift truck carrying a load whilst travelling over a rough floor
  • Levelling of vehicles and systems carried whilst travelling at speed over rough ground.
  • Experimental reactive armour for protection of tracked and wheeled vehicles against IED's
