Are you developing construction machinery or related equipment?

If so, you may have needs like validating or troubleshooting the following issues.

  • Noise and vibration of the powertrain and related components
  • Driving performance on rough roads like unpaved roads, gravel roads, swamps
  • Side slope stability, grade climbing
  • Loads on ultra-large machines that are difficult to measure
  • Durability of components
  • Stability during operation (excavating, loading, unloading, ...)
  • Ride Comfort, Steering Stability, Steering Response


Multibody dynamics simulation using RecurDyn is used in construction machinery and equipment development for such things as.

  • Prediction of the noise and vibration during driving or operation
  • Prediction of the load and stress to each component
  • Design to avoid the rollover during excavating or loading/unloading operation
  • Evaluation of vibration characteristic differences arising from track link material (Rubber, steel)
  • Determination of driving loads on tracks and prediction of friction wear
  • Durability analysis of components in an ultra-large machine that are difficult to test
    • For example: gears, bearings, races, arms, struts
  • Driving performance and stability on rugged slopes
  • Construction machinery powertrain performance, including NVH evaluation
  • Analysis of lubricating film of various parts
  • Design optimization to improve the fuel efficiency
  • Optimization of control algorithms to improve the efficiency of hydraulic and electric excavators
  • Ride comfort and operator safety evaluation
