Title:
ANALYSIS DEVICE AND ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2014/157495
Kind Code:
A1
Abstract:
This analysis device (11) constructs an analytical model (21) from a circuit board (22) and a medium (M), as well as providing a concentrated load grouping (CLG) comprising concentrated loads (CLa) - (CLd) on the circuit board (22). At this time, the concentrated loads (CLa) - (CLd) are established in such a way that the sum of the mutual vectors is zero, and the torque relating to the center of gravity is zero. The analysis device (11), applying a finite element technique to the analytical model (21), calculates vibration of the circuit board (22) when the concentrated loads (CLa) - (CLd) are vibrated at a constant cycle. Pressure changes of the medium (M) are computed from the vibration of the circuit board (22), and the pressure changes are converted to acoustic pressure.
