一种振动、噪声复合试验设备

Combined vibration and noise testing equipment

Abstract

一种振动、噪声复合试验设备,其特征在于:主要由噪声试验箱、振动台和控制箱三部分组成;其中,所述噪声试验箱为一密闭箱体,其内部为一声腔,该声腔内设有至少一套发声装置;所述噪声试验箱对地设置一支架支撑,并在噪声试验箱的下方形成一容置空间,所述振动台设于该容置空间内;所述振动台的台面上固定设置一延伸头,所述噪声试验箱底面上对应延伸头开设有一接口,所述延伸头经该接口伸入声腔中,且在延伸头周向与接口间设密封装置连接;所述控制箱内设控制电路,用于控制噪声试验箱和振动台。本实用新型不仅能够同时提供振动、噪声试验的复合试验,还可以提供单独的振动试验或者单独的噪声试验,填补了该领域的国内空白。
Combined vibration and noise testing equipment is characterized by consisting of a noise test box, a vibrating table and a control box. The noise test box is a closed box with an internal sound cavity, at least a sounding device is arranged in the sound cavity, the noise test box is provided with a support towards the ground, a containing space is formed below the noise test box, the vibrating table is arranged in the containing space, an extension head is fixedly arranged on the top of the vibrating table, a joint corresponding to the extension head is arranged at the bottom surface of the noise test box, the extension head extends into the sound cavity via the joint, a sealing device for connection is arranged between the periphery of the extension head and the joint, and a control circuit is arranged in the control box and used for controlling the test noise box and the vibrating table. The combined vibration and noise testing equipment can be used for combined test for vibration and noise simultaneously, can also be used for independent vibration test or noise test, and fills domestic gap in the field.
