RecurDyn helps ensures passenger safety in faster, higher capacity detachable chair lifts
Software facilitates dynamic studies of complex multi-body models to predict accelerations; verify, shape and size structural parts
Dynamic studies are required to predict the accelerations, verify that the cams are properly shaped, and to extract the loads to structurally size the parts.

Dynamic CFD analysis of a vertical-axis washing machine with a hydraulic balancer
The article describes a study on the behaviour of a vertical-axis washing machine's hydraulic balancer, which is a critical component that helps to balance the load during the spinning phase of the washing cycle. The study was conducted by SPM, a company that specializes in dynamic analysis, to confirm a hypothesis that the flexibility of the tub was causing the imbalance and to validate a proposed modification to stiffen the structure.

RecurDyn enables engineers to create full FE models of flexible belts
Faciliitates extraction of stresses and strains from entire structure and takes into account all friction forces, shape and misalignment dynamics and structural flexibility
A virtual prototype of a belt must necessarily include the high flexibility of the belt itself, as well as a detailed description of the contacts. This is another scenario where RecurDyn provides better functionality than its competitors.

Improving the reliability of multibody simulation by implementing a hysteretic tyre model for radial dynamics
Multibody simulation is integral to engineering, enabling precise analysis of structural loads and dynamic behaviours in complex systems. In the context of forklifts, where tyres play a critical role due to the absence of suspension systems, accurate tyre modelling is essential. This study develops and validates a hysteretic Bouc-Wen model for the radial dynamics of solid rubber tyres to enhance simulation reliability.
