Abstract

The invention relates to the technical field of mechanical vibration measurement. The invention further discloses a mechanical vibration electric measurement device based on the capacitance principle.The device comprises a fixing frame; fixing rods are fixedly installed at the left end and the right end of the interior of the fixing frame; connecting rods are slidably connected with the interiorsof the fixing rods; suction cups are fixedly installed at the lower ends of the connecting rods through buffer springs, and a moving plate is fixedly installed between the fixing rods. The inventiondiscloses the mechanical vibration electric measurement device based on the capacitance principle. The device is tightly adsorbed on a machine to be measured through the suction cups; the machine is started, and the machine drives a dielectric block to vibrate together; in the vibration process, the dielectric block moves in an electric field formed by electrode plates; the change of the electricquantity can be changed along with the increase or decrease of the area, opposite to the electrode plates, of the dielectric block; and the mechanical vibration of the machine can be measured according to the change of the electric quantity in cooperation with the electric measurement instrument, so that the effect of convenient measurement is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical vibration measurement, in particular to a mechanical vibration electrical measurement device based on the principle of capacitance. Background technique [0002] With the rapid development of industrialization, measurement technology has been in the process of rapid development. Traditional vibration measurement has low accuracy in monitoring the operating status of machines and structures and in fault diagnosis. Mechanical vibration measurement methods are mainly divided into three types: electrical measurement Method, mechanical method, optical method, the most widely used is the electrical measurement method. [0003] The electrical measurement method is to convert the vibration of the measured object into electrical quantity, and then measure it with an electrical measurement instrument. However, the current electrical measurement method measures mechanical vibration, and the electrical mea...
