A static analysis calculates the effects of steady loading on a structure, while ignoring inertia and damping effects, such as those caused by time-varying loads. A static analysis can, however, include steady inertia loads (such as gravity and rotational velocity), and timevarying loads that can be approximated as static equivalent (wind and seismic loads commonly defined in many building codes) Static analysis is used to determine the displacements, stresses, strains, and forces in structures or components caused by loads that do not induce significant inertia and damping effects.
Dynamic analysis can be used to determine the vibration characteristics (natural frequencies and mode shapes) of a structure or a machine component while it is being designed. It also can be starting point for another, more detailed, dynamic analysis, such as a transient analysis, a harmonic analysis, or a spectrum analysis. Dynamic analysis is the study of the dynamic properties of structures under vibrational excitation.
Mechanical causes of motion – There are many mechanical causes of motion such as force, moment, work, impulse, and power, etc.
Mechanical responses – Two types of spatial motion for a physical object are translation and rotation. A general motion consists of these two motion components, which are independent of each other. This lays an important theoretical basis for rigid-body kinematics.
Cause and effect relationship – The governing physical laws are Newton’s three laws of motion and Euler’s equations. When Newton’s second law of motion is integrated, it becomes either the principle of work and energy or the principle of impulse and momentum. These laws are the foundations of all mechanics studies.
We provide technology to correctly include a component’s flexibility even in presence of large overall motion and complex interaction with other modeling elements.
Motion analysis offerings provide a variety of contact modeling functionality. Rolling and sliding contacts and impact can be represented between rigid bodies, flexible and rigid bodies as well as between two flexible bodies.
Contact primitives provide a highly-efficient solution for simple geometry. More sophisticated methods are used for contact between complex geometries both rigid and flexible. In no case is a previous knowledge of "contact regions" required.
