Embodiment Construction

[0053] Below in conjunction with accompanying drawing, the present invention will be further described:

[0054] A general elastic vibration isolation device for sensor suspension measurement, comprising a base 1, a trapezoidal support 2 fixed on the base 1, a sensor 4 and an elastic element 3 connecting the sensor 4 and the trapezoidal support 2, the elastic element 3 There are four, respectively connecting the four corners of the trapezoidal bracket 2 with the sensor 4, and the elastic element 3 is a rubber elastic element.

[0055] By comparing the material components and hardness, a rubber elastic element 3 with less rigidity is selected, and its cross-sectional area S is S 1 , S 2 , S 3 original length L 0 For the tensile stiffness tests of A, B, and C, the stiffness values ​​of the rubber elastic element 3 at different elongation ratios are obtained, and analyzed to obtain the corresponding elongation ΔL when the stiffness is the smallest min . Simultaneous measurem...

Abstract

The invention belongs to the vibration isolating technology field and discloses a general elasticity and vibration isolating apparatus for sensor suspension measurement and design method thereof. The apparatus comprises a base, a trapezoidal support fixedly arranged on the base, a sensor, and rubber elastic elements connecting the sensor with the trapezoidal support. There are four such rubber elastic elements which let the four angle points of the trapezoidal support be connected with the sensor. The design method is based on the natural frequency of the vibration isolating apparatus, and optimizes design parameters including the stiffness, suspension length, elongation and suspension structure of the rubber elastic elements so as to provide the maximum vibration attenuation effect for the measurement sensor.

Description

technical field [0001] The invention relates to the technical field of vibration isolation, in particular to a design method of a general elastic vibration isolation device used for sensor suspension measurement. Background technique [0002] When various sensors are used for sound measurement (such as acoustic probe), distance measurement (such as laser range finder) and other measurement processes, the measurement results have high requirements for the placement stability of the sensor. If the external vibration interference passes through the sensor The transmission of the installation base, bracket and other mechanisms to the sensing element will cause a large measurement error and reduce the measurement accuracy. Therefore, it is necessary to use a vibration isolation device to suspend and fix the sensor to reduce the impact of external environmental vibration on the measurement. The matching design of the elastic element stiffness and the vibration isolation structure ...
