RECURDYN

RecurDyn is an engineering software technology to analyze the dynamic behavior of systems which include both rigid bodies and flexible bodies. It combines MBD (Multi-Body Dynamics) to analyze the motion of rigid bodies and FEM (Finite Element Method) to analyze the motion, stresses, and deformation of flexible bodies. RecurDyn’s solver combines these two components in a single solver. This provides RecurDyn with a much faster and much more robust solver than it could be achieved through co-simulation.

RecurDyn is used in many fields such as automotive, defence, aviation, space, and shipbuilding industries.

RecurDyn Analysis Capabilites;

  • • Rigid and Flexible Multibody Dynamic Analysis
  • • Kinematic Analysis
  • • Static Analysis
  • • Design Studies and Design of Experiments
  • • Sensitivity Analysis
  • • Vibration (Linear) Analysis

1. Tire & Suspension

Analyzes the characteristics of the vibration delivered to the tire and suspension when the automobile runs in various terrains.


2. Gear

RecurDyn/Gear provides the easier modeling and the analysis of complicated gear train system in the graphical user interface. RecurDyn/Gear can analyze vibration characteristics and DTE (Dynamic Transmission Error) which is occurred from the real contact characteristic among gear teeth, considering user-defined backlash and tolerance. Also, the post-process function provides to check the information about the contact normal forces and friction forces in the contact point at each time step.


3. Engine

RecurDyn's engine toolkits dramatically simplifes the modeling and analysis of the major components of internal combustion engine systems, such as valves, pistons and crankshafts. This allows you to create and analyze highly realistic engine models quickly and easily.


3.1. Valve

The RecurDyn/Valve toolkit is for the design and analysis of valve train systems. It automates the creation of valve train assemblies. This toolkit supports various valve types and camshafts. It also allows for the use of flexible bodies in the analysis.


3.2. Piston

The RecurDyn/Piston toolkit automates the creation of engine piston systems. The toolkit is designed for contact analyses of pistons and cylinders. It can perform a bearing analysis that models the lubrication properties of EHD bearings between a piston pin and connecting rod or between a piston pin and piston (RecurDyn/EHD is required).


3.3. Crank

The RecurDyn/Crank toolkit automates the creation of drive shaft-related parts, such as crankshafts, balancing shafts, and flywheels.


4. Belt

RecurDyn/Belt is used in a wide variety of fields from automotive timing and front-end accessory drives to lawn mowers, washing machines, and road milling equipment. Modeling belt and pulley systems with other CAE software requires significant time. RecurDyn/Belt makes it easier to model and simulate simple to complex three-dimensional belt drive systems.


5. Chain

RecurDyn/Chain automates the process of defining a chain system and supports standard chain entities such as sprockets, rollers (idlers), guide rails and lateral guards. Roller chain and silent chains can be modeled and analyzed in this toolkit.


6. HM Track

RecurDyn Track HM (Track High Mobility) is a toolkit which provides the modeling function of moved vehicles like the tank, personnel carriers used in the military or recreational vehicles such as snowmobiles. by the track the simulation function. Main elements of tracked vehicle are provided as libraries and the user can perform the fast analysis by the optimized solver.


7. LM Track

RecurDyn TrackLM (Track Low Mobility) is a toolkit which provides the modeling function of moved vehicles by the track in the construction equipment or the heavy industry equipment and the simulation function. Main elements of tracked vehicle are provided as libraries and the user can perform the fast analysis by the optimized solver.
