This tutorial was created using ANSYS 7.0 The purpose of this tutorial is to show the steps involved to perform a simple transient analysis. The simple cantilever beam is used in all of the Dynamic Analysis Tutorials. We need to establish initial conditions (the condition at Time = 0). Since the equations for a transient dynamic analysis are of second order, two sets of initial conditions are required; initial displacement and initial velocity.
We will use the Reduced Method for conducting our transient analysis. Therefore, a modal analysis of the structure should be initially performed fluid structure interaction to provide information about the structure's dynamic behavior. We did not specify damping in our transient analysis of the beam.

Cases where such effects play a major role are under step or impulse loading conditions, for example, where there is a sharp load change in a fraction of time. The Mode Superposition Method: This method requires a preliminary modal analysis, as factored mode shapes are summed to calculate the structure's response.
If it is hanging from a cable, when the beam accelerates downward at 1.8 G, the mass that is hanging below can only accelerate downward at 1 G and the cable goes slack. ANSYS Motion, now in the Mechanical interface, is a third generation engineering solution based on an advanced multibody dynamics solver.

We will use the Reduced Method for conducting our transient analysis. Therefore, a modal analysis of the structure should be initially performed to provide information about the structure's dynamic behavior. We did not specify damping in our transient analysis of the beam.
We will now re-run our transient analysis, but now we will consider damping. In addition to the basic package ANSYS Motion offers additional toolkits so users working in areas with specific multibody dynamic needs can work faster and more efficiently. We can define each load step (load and time at the end of load segment) and save them in a file for future solution purposes.

However, if stresses and forces are of interest than, we would have to Expand the Reduced Solution. We may have captured some response at the second mode at 52 Hz of the beam. We can also solve for each load step after we define it. We will go ahead and save each load step in a file for later use, at the same time solve for each load step after we are done defining it.
