Horizontal direction displacement measuring device of missile vertical launch initial segment

Abstract

The present invention discloses a horizontal direction displacement measuring device of a missile vertical launch initial segment. The horizontal direction displacement measuring device of the missile vertical launch initial segment comprises a displacement sensor (1), a supporting base (2), a supporting rod (3), a shaft (4) and a metal roller (5). A measuring rod of the displacement sensor (1) is in screw joint with the supporting base (2), the supporting base (2) is fixedly connected with the supporting rod (3), the supporting rod (3) is fixedly connected with the shaft (4), and the metal roller (5) and the supporting rod (3) are connected via the shaft (4). The device of the present invention solves the problem that when the horizontal direction displacement of the missile vertical launch initial segment is measured, a frictional force displacement sensor deviates from a horizontal direction, so that the displacement measurement precision is reduced, even the displacement sensor is damaged, and enables the horizontal direction displacement measurement cost of the missile vertical launch initial segment to be reduced and the displacement measurement precision to be improved.

Description

technical field [0001] The invention relates to a displacement measuring device, in particular to a horizontal direction displacement measuring device for the initial stage of vertical launch of a missile. Background technique [0002] In the aerospace test, there is a horizontal displacement in the initial stage of the vertical launch of the missile, and the horizontal displacement must be controlled within a reasonable range, so each test must measure the horizontal displacement of the missile in the initial stage of the vertical launch. The simple, effective and high-precision measuring device adopts a displacement sensor installed along the horizontal direction on the side of the missile. The horizontal displacement generated when the missile is launched vertically drives the measuring rod of the displacement sensor to generate an output signal. This output signal is the vertical launch of the missile. Horizontal displacement. Since the displacement sensor is installed ...
