Actual-model Example for Linear Dynamic Analysis

Analysis Model

For the linear dynamic analysis, the mechanical component shown in Figure 9.5.1 is used as the actual model. Four verification cases are defined for this actual model with different loading conditions and damping coefficients. Table 9.5.1 lists these cases.
