Abstract
The utility model relates to a frequency response characteristic device of a vibration pickup device, which comprises a first clamp, a second clamp, a vibration exciter, a base, a first fixing bolt, a second fixing bolt, a vibration platform, a third fixing bolt and a vibration pickup device. The vibration pickup device is fixed on the first clamp and is arranged on the vibration platform, the vibration platform is fixed on the base, and the vibration exciter is arranged on the second clamp and is arranged on the base. The product has a simple structure. The framework type vibration platform has a small mass and good flexibility and is sensitive to vibration exciting force. The vibration pickup device is fixedly arranged on the framework type vibration platform, the additional vibration between the vibration platform and the vibration pickup device is eliminated, the measurement results of the vibration pickup device is closer to frequency response characteristics of the vibration pickup device, and thus the desired testing effect can be achieved.
Description
Technical field: the utility model relates to a kind of vibro-pickup frequency response characteristic device.
Background technology: at present, existing vibro-pickup frequency response characteristic device, mostly be the shaking table of box-type greatly, quality is big, and poor flexibility is insensitive to the exciting force reaction, and vibro-pickup directly is placed on the casing, the vibration of casing can make vibro-pickup produce some additional vibration signals, and this vibration signal is the frequency response characteristic factor that influences vibro-pickup self, and measurement result is occurred than mistake.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of vibro-pickup frequency response characteristic device is provided, it has mainly solved existing vibro-pickup frequency response characteristic device, mostly be the shaking table of box-type greatly, quality is big, poor flexibility can make vibro-pickup produce some additional problems such as vibration signal to exciting force reaction vibration insensitive and casing.The purpose of this utility model is achieved in that vibro-pickup frequency response characteristic device is made of: first anchor clamps, second anchor clamps, vibrator, base, first set bolt, second set bolt, shaking table, the 3rd set bolt, vibro-pickup.Vibro-pickup is fixed on first anchor clamps, and is installed on the shaking table by the 3rd set bolt, and shaking table is fixed on the base by second set bolt, and vibrator is fixed on second anchor clamps, and is installed on the base by first set bolt.This product structure is simple, the frame-type shaking table, the shaking table quality is little, good springiness, exciting force is quick on the draw, and vibro-pickup is fixedly mounted on the frame-type shaking table, has eliminated vibration additional between shaking table and vibro-pickup, the measurement result that makes vibro-pickup is more near the frequency response characteristic of vibro-pickup self, thereby reaches the detection effect of expection.
