Journal Bearing is a Force Element used to model radial or axial journal bearings using a nonlinear stiffness and damping law. This Force Element can model any kind of radial or axial bearing where a force law acting on only two Markers would be unsatisfactory. Simpack Journal Bearing acts between several Markers on the shell and one center Marker on the shaft. A 3D effect can be achieved by adding several Force Elements in a row.
This Force Element is used to simulate hydrodynamic bearings by solving the Reynolds equation accurately and efficiently. The element includes rigid body hydrodynamics (HD), one-sided and double-sided elasto-hydrodynamics (EHD and DEHD). Special design parameters allow for easy and user friendly consideration of oil bores, grooves etc. Any level of detail can be simulated.
Simpack BEARINX Map for Rolling Bearings enables the software BEARINX® from Schaeffler Technologies to be used in Simpack. BEARINX® allows the calculation of accurate bearing forces and torques for a large number of rolling bearings.
Non-linear stiffness as well as coupling effects and bearing clearance are described by a characteristic field in a BEARINX Map (.bxm) file, which must be provided by Schaeffler Technologies.
Rolling Bearings are a key element for simulating power transmission, e.g. in automotive and wind turbine applications. This Force Element is used to efficiently simulate any type of ball, cylinder, needle and tapered rolling bearing. Geometrical properties are used to calculate the transmitted forces and torques. Non-linear stiffness, clearance, cross-coupling and load dependent damping are all considered.
Supported Bearing Types:
Ball Bearings: deep groove, angular, thrust, four point
