| General | The displacement is analyzed when vibration is applied to the feet of leads of a component. In the harmonic analysis, sinusoidal vibration is only analyzed. In the transient analysis, arbitrary waveform can be analyzed. *The stress-transient analysis is optional. |

| Analysis Model | Timesteps setting is an important factor for the transient analysis. By performing a resonant analysis in advance to obtain the frequency of the resonance mode excited by the vibration displacement, it can be used as a reference when setting appropriate timesteps. In this example,the timesteps are set considering the two resonance modes that are expected to occur due to the vibration displacement in the Z direction. High speed and low speed of vibration waveforms are prepared for comparison. |
| Result | In the case of high speed vibration waveform, the vibration displacement shows the high-order resonant mode. In the case of low speed vibration waveform, the low-order resonant mode is shown. The stresses generated at the leads show different behavior according to the vibration speed. |
