What's New and Overview of RecurDyn 2024

EnginSoft USA is excited to share with you the new capabilities and enhancements of RecurDyn 2024. For example:

  • FFlex Static: A more stable static analysis can be performed for various models. In addition, various improvements have been made related to static analysis, including supported force display, supported contact pressure, show static animation option, and scenario output control.

  • Linked Assembly: With the new Linked Assembly toolkit, the Assembly Bodies such as the Track Link, Chain Link, Belt Segment, and Passing Bodies such as Pulley, Sprocket, Wheel, Flange, and Guide, can all be created using CAD Geometry rather than the geometry from the specific toolkits. 

  • Geo Sphere Contact: Geo Curve 3D and Geo Sphere to Curve 3D are new contacts that are optimized for Curves 3D contact modeling. Geo Curve 3D Contact has parameters similar to those of the existing Geo Curve Contact 2D. However, it can be also used to simulate 3D phenomena by setting the Curve's thickness using the Radius field. It can be applied to both rigid and flexible bodies, and you can select either Curve or Circle as the Geometry Type in the Action Geometry.

  • Buoyancy Force: The Buoyancy Force function that can calculate and apply buoyancy and flow effects has been added. You can create a Buoyancy force by selecting a reference marker to define the fluid surface and flow velocity direction, and a surface or solid that will be subject to buoyancy. Buoyancy can be applied to both rigid and flexible bodies (referencing a Patch Set).

  • Gap Force: This new feature applies forces to both the Action Body and Base Body to maintain a user specified gap between the Action Body and Base Body. The gap force is used to represent the effect of a gap imposed by air or magnetic forces.

  • JMAG RT: A new JMAG RT block has been added. The JMAG RT (*.RTT file) model is a 1D model of a motor's characteristics obtained from the JMAG simulation software for electrical device design and development. This allows models containing 3 phase PMSM motors represented in JMAG RT to be modeled in CoLink and enables the confirmation of control algorithms for such models, as well as the simulation of RecurDyn models that include the motor.
This webinar will not only explain the RecurDyn 2024 enhancements, but will also provide examples of how to best use the enhancements to broaden what you can simulate and improve the efficiency of your simulation processes.

Understand, Predict, and Optimize Real-World Designs with Multiphysics Simulation

In the past, only one type of physics could be considered at one time and the models were coarse. As computer hardware became faster and the simulation software more capable, more detailed models could be used. However, these details models continued to lack the ability to study the interaction between different types of physics. For this reason, we advocate the use of multi-disciplinary technologies to provide engineers, at every stage of the product cycle, a clear picture of the interactions that define the overall product behavior. No matter how small, each part and process in the chain must be considered when creating robust, accurate, and reliable simulation models. Join our webinar on to learn how this multi-disciplinary approach can help your design process.

Optimize your Product Design

Simulation is a key piece of the product development process but part of a larger puzzle. Making the best use of all available human and compute resources requires a digital pipeline to contextualize information as it moves through an organization. Optimization tools such as Iliad fill this role by providing a platform to connect different software tools and data sources while visualizing their connections. Once a process is defined it can be automated in a variety of ways, from simple DOE testing to completely hands off optimized designs. Join us to learn how OmniQuest’s Iliad can help your business.

Modeling Springs Accurately Using Multibody Dynamics

In certain high-speed applications involving springs, obtaining accurate simulation results requires the detailed modeling of the springs beyond just the forces they exert between their endpoints. Increased accuracy requires that the mass of the spring be taken into account to capture the inertial effects of the coils. Capturing the true behavior also requires the modeling of contact between the spring coils and themselves and with other objects. This webinar will show you that by using a powerful Spring Toolkit, you can include all of the detailed behavior of springs to obtain accurate simulation results and improve product design.

Advantages of Using RecurDyn for NVH Analysis

RecurDyn multibody dynamics and multiphysics is a good platform for NVH because excitations that occur in a mechanical system are often nonlinear: 1) Flexible bodies with large deformations and momentum effects, 2) Nonlinear relationships with other types of physics. In this presentation we will validate the accuracy of this approach by the close correlation of the simulation and experimental results. The benefits of design changes to NVH performance are accurately identified in simulation because the inputs not being changed can be locked to be the same (unlike physical testing that has variability in test and design inputs). Noise that is emitted from flexible bodies can be estimated by the RecurDyn acoustics module. Such estimates can be used to suggest design changes (ribs or other stiffening) for reducing noise.

Multi-Physics-Enabled Fatigue Analysis Using RecurDyn/Durability

Fatigue can turn a perfectly functional part into an expensive warranty problem. Anytime a part experiences dynamic stresses it should be evaluated for fatigue performance to ensure it will last as long as intended. Fatigue analysis requires an accurate time history of strains in the component, and a multi-physics simulation is often needed in order to calculate accurate loads in the system. RecurDyn provides excellent multi-physics capabilities for mechanical systems that include assemblies in motion.

In this webinar you will see a refresher course on what fatigue is and how a part's expected lifetime is calculated. Once the basics have been covered you'll see how RecurDyn's Durability toolkit can help you make these calculations for complex real-world parts.
