Aisin Seiki has selected LMS Virtual.Lab Motion to simulate and optimise the dynamic performance of vehicle components and systems.
LMS Virtual.Lab Motion allows Daf engineers to accurately predict key engine attributes including torsion vibrations on the crankshaft and camshaft, flywheel whirl, bearing loads and camshaft torque.
Dynamic stresses can be evaluated throughout the powertrain system.
Also, loads can be used as input to LMS Virtual.Lab Noise and Vibration in studying engine vibrations and analysing potential sources of noise problems.

Simulation speeds transmission development
Toshiba has deployed the LMS Virtual.Lab Motion multibody simulation software to support the development of advanced power transmission equipment in its Power Systems Division.
In this way, Daf Trucks can quickly evaluate the performance envelope of different engine configurations and balance often-conflicting requirements including drive power, fuel consumption, weight, reliability, structural vibration and engine sound - all done without expensive and time-consuming prototype testing.
"Daf Trucks selected LMS Virtual.Lab Motion for its powerful modelling and simulation capabilities", commented Eric van Velthooven, Research Engineer at Daf Trucks.
"The software enables us to accurately simulate complex engine mechanisms and to quickly identify and correct potential problem areas up front in design".
According to van Velthooven, the use of parameterised models of powertrain subsystems such as the gear train, camshaft, flywheel, and hydrodynamic bearings allows engineers to easily modify designs and quickly evaluate alternatives.
Tight integration provided by LMS Virtual.Lab between motion simulation and other simulation disciplines supports DAF in assessing the overall impact of these design modifications on engine performance, vibration and fatigue life.
"With LMS Virtual.Lab Noise and Vibration, dynamic loads from motion simulation can be readily applied to a complete engine assembly model".
"As a result, we can accurately assess the NVH performance of a specific engine configuration and eliminate the root causes of specific noise or vibration problems", explained Eric van Velthooven.
"The integration of key simulation processes and disciplines in LMS Virtual.Lab allows us to gain valuable insight into the key performance attributes early in development and to efficiently configure our engines for specific applications".
"From a business perspective, faster turnaround of refined designs for multiple product configurations gives us an advantage we can certainly leverage in the globally competitive diesel engine market". Request a free brochure from LMS International ...
