Simpack Contact allows users to apply contact forces between contours and/or surfaces. Several methods are available for determining contact location. Accessible force types include hertzian, stick-slip friction, and plastic deformations, among others. Users can also define contact between generalized CAD geometries.
Simpack User allows users to implement their own modeling elements into Simpack as FORTRAN 90 or C subroutines. Users can also configure the element's input window.
User-defined modeling element categories include Force and Control Elements, Joints, Excitations, Input functions, 2-D Plot Filters, etc.
In today's world of increasing computing power and electronics, the ability to include control systems within simulation models is indispensable. Simpack control enables users to build up active controllers for simulating complete mechatronic systems.
Simpack NVH (Noise, Vibration, Harshness) assists users in carrying out vibration analyses within Simpack.
Frequency-domain analyses of linearized models can be performed using Linear System Analysis (LSA). The LSA solver offers three operating modes: frequency response, system response and power response.
Operating Deflection Shapes (ODS) of a time-domain analyses can be executed and animated in the post-processor.
Non-linear Frequency Pass (NLFP), for efficient frequency analysis of non-linear models in the time-domain, is also available with Simpack NVH.
Simpack Dynamic Bushing is a rubber and hydromount Force Element, which considers the non-linear effects--including the frequency and amplitude dependent characteristics--of a bushing or hydromount. The effects of various standard force elements are combined within the one element for easy switching between levels of complexity.
The Simpack Order Analysis Filters are intended for drivetrain analyses. They perform a spectral analysis of a signal. The width of the Fourier Transform window is dependent on the referenced rotational velocity of the drivetrain. The assignment between the frequency of rotation (and the orders of this frequency) and the analyzed signal can then be performed.
