Title:
DAMPING ANALYSIS METHOD FOR PEDESTRIAN WARNING LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2020/248460
Kind Code:
A1
Abstract:
Disclosed in the present invention is a damping analysis method for a pedestrian warning loudspeaker, which solves the problems existing in a traditional test method of the necessity of preparing a sample in advance, time-consuming and laborious sample development, high costs, investment, etc. A damping analysis method for a pedestrian warning loudspeaker, comprises: providing a geometric model of a damping system of a pedestrian warning loudspeaker, the damping system comprising a loudspeaker box, a damper and a support; establishing a finite element model of the damping system according to the geometric model, solving the finite element model, and obtaining, by means of post-processing, a change relationship between a displacement transmissibility of the damping system and a frequency; wherein the finite element model is solved by using a steady state analysis method, and the theoretical equations for solving are as follows: (I); and the displacement transmissibility satisfies the following equation: (II).
