Abstract

The invention discloses a shock absorption analysis method for a pedestrian warning loudspeaker, and solves the problems of time and labor consumption, high cost, investment and the like due to the fact that a sample needs to be prepared in advance in a traditional test method. The shock absorption analysis method of the pedestrian warning loudspeaker provides a geometric model of a shock absorption system of the pedestrian warning loudspeaker, and the shock absorption system comprises a loudspeaker box body, a shock absorber and a support. A finite element model of the shock absorption systemis established according to the geometric model, the finite element model is solved, and the change relation of the displacement transmissibility of the shock absorption system along with the frequency is obtained through post-processing, wherein the finite element model is solved by adopting a steady-state analysis method, and a theoretical equation for solving is as follows: the displacement transmissibility meets the following equation shown in the description.

Description

technical field [0001] The invention belongs to the field of pedestrian warning loudspeakers, and relates to a shock absorption analysis method for pedestrian warning loudspeakers. Background technique [0002] With the promotion of new energy vehicles, pedestrian warning speakers have also become a focus. Since the pedestrian warning device is usually installed in the engine compartment, the pedestrian warning speaker not only needs to ensure its normal operation but also needs to ensure that it does not affect the surrounding structures during normal operation. The shock absorber is an important part to maintain the structural stability of the pedestrian warning loudspeaker, and plays the role of buffering and shock absorption. The shock absorber can reduce the influence of the pedestrian warning and health-preserving device itself on the surrounding structures, and can also reduce the influence of the surrounding structures on the pedestrian warning and health-preserving...
