LMS International has announced an extension to its LMS Virtual.Lab Motion product with breakthrough solver technologies and new modelling capabilities to simulate real-life system dynamics.
LMS International, the engineering innovation company, has announced an extension to its LMS Virtual.Lab Motion product with breakthrough solver technologies and new modelling capabilities to simulate real-life system dynamics The new Auto-Recursive Solver records up to 60% time savings in solving complex simulation models with a long series of linked components and high number of contact points between components
This eliminates the calculation bottleneck in simulating the dynamic behaviour of timing chains, belts, tracked vehicles, and complex production machines.
As a result, LMS Virtual.Lab Motion allows users to accurately simulate the internal forces and accelerations of these mechanisms, which are typically very difficult to measure through prototype tests.
The new Auto-Recursive Solver takes advantage of repeated bodies connected by revolute, rev-rev, or rev-trans kinematic constraints.
When this topology is present in a model, it can be exploited to solve the acceleration terms more efficiently compared with a traditional motion solver based on Cartesian equations.
LMS Virtual.Lab Motion offers a unique implementation of the Auto-Recursive Solver, since it coexists with the traditional motion solver in a single, integrated solution.
Users benefit from the performance and accuracy of both solver solutions combined in a single simulation model.
LMS Virtual.Lab Motion Rev 5 combines the deployment of the Auto-Recursive Solver with a new sub-mechanisms capability.
This new feature introduces a building block approach to efficiently model and simulate complex mechanism models like an engine valve train or a tracked vehicle.
It intelligently avoids the usage of redundant geometry information when repeated elements are involved.
This makes the resulting simulation models smaller and more efficient to solve, resulting in less memory consumption and faster calculation runs.
With Rev 5, LMS Virtual.Lab Motion also gains a reliable and efficient algorithm to compute the contact forces and local deformation of a flexible body intermittently hitting a rigid sphere.
This allows engineering teams to take local deformation in contact regions into account, and to add another real-life dimension to motion simulation.
Typical applications for this new functionality include sunroofs, roller bearings, telescopic shafts, valves, timing chains, elevators, aircraft wing flap and latch mechanisms.
"LMS Virtual.Lab Motion offers a complete and integrated solution to realistically simulate the dynamics of mechanical systems, and accurately determine the resulting internal dynamic loads and stresses", commented Willy Bakkers, Executive Vice-President and General Manager of the LMS CAE Division.
"With the introduction of Rev 5, LMS Virtual.Lab Motion gains new solver capabilities and efficient modelling techniques for the simulation of complex mechanical assemblies".
"LMS Virtual.Lab Motion's capabilities have been extended to accurately simulate the dynamic performance of new designs early in the development cycle". Request a free brochure from LMS International ...
