Abstract
The invention discloses a horizontal movement acceleration measurement instrument which comprises a base, a vertical plate, a revolving shaft, a straight rod, an acceleration pointer and an acceleration scale. The vertical plate is vertically fixed to the base and the revolving shaft is vertically fixed to the middle upper portion of the vertical plate. The straight rod is uniform in size, with one end fixed to the revolving shaft and the other end connected to the acceleration pointer. The acceleration scale is fixed to the middle lower portion of the vertical plate and is arc shaped. The horizontal movement acceleration measurement instrument is simple, visual, cheap and firm and provides an effective way for people to measure horizontal acceleration since acceleration values can be read from the acceleration scale directly.
Description
Technical field
The invention belongs to surveying instrument field, relate to a kind of acceleration analysis instrument, be specially a kind of tangential movement accelerograph.
Background technology
Speed and acceleration are all the physical quantitys of describing object moving state, and wherein acceleration is the physical quantity of describing object speed variation speed.The acceleration of measuring object of which movement, is conducive to the assurance to object moving state.Existing acceleration measurement device is mostly with sensor, and its principle and structure are comparatively complicated, cost is higher.
Summary of the invention
Object of the present invention is that a kind of physical principle of exploitation is clear, simple in structure, cost is low, measure tangential movement accelerograph accurately.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A kind of tangential movement accelerograph, comprises base, riser, rotating shaft, straight-bar, acceleration pointer and acceleration scale; Base, riser are rectangle, and riser is vertically fixed on base, and rotating shaft is vertically fixed on riser middle and upper part; Straight-bar even thickness, straight-bar one end is fixed in rotating shaft and can in perpendicular, freely rotates around the shaft, and the straight-bar other end connects fixing with the acceleration pointer that is used to indicate accekeration; Acceleration scale is fixed on riser middle and lower part, acceleration scale be centered by rotating shaft, radius is not less than the circular arc of straight-bar length, on acceleration scale, mark has angle and the accekeration corresponding with angle simultaneously.
Described straight-bar is stainless steel, in case get rusty.
Described base below is provided with the leveling serew for base Level tune.
The present invention is simple in structure intuitively, cost is low, not fragile, can directly read accekeration from acceleration scale, for the measurement of horizontal acceleration provides a kind of effective way.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is formation schematic diagram of the present invention.
Fig. 2 is principle of the invention analysis chart.
In figure: 1. base; 2. riser; 3. rotating shaft; 4. straight-bar; 5. acceleration pointer; 6. acceleration scale; 7. leveling serew.
Embodiment
?as shown in Figure 1, the present invention includes base 1, riser 2, rotating shaft 3, straight-bar 4, acceleration pointer 5 and acceleration scale 6; Base 1, riser 2 are rectangle, and riser 2 is vertically fixed on base 1, and rotating shaft 3 is vertically fixed on riser 2 middle and upper parts; Straight-bar 4 even thickness, straight-bar 4 one end are fixed in rotating shaft 3 and can 3 in perpendicular, freely rotate around the shaft, and straight-bar 4 other ends connect acceleration pointer 5 and are used to indicate accekeration; Acceleration scale 6 is fixed on riser 2 middle and lower parts, acceleration scale 6 for centered by rotating shaft 3, radius is slightly larger than the circular arc of straight-bar 4 length, on acceleration scale 6, mark has angle and the accekeration corresponding with angle simultaneously.
Straight-bar 4 is stainless steel, in case get rusty.
Base 1 below is provided with the leveling serew 7 for base 1 Level tune.
As shown in Figure 2, in figure, the quality of straight-bar 4 is m, length is L, when with the accelerated motion to the right of acceleration a along continuous straight runs, straight-bar 4 departs from vertical position and 3 turns over clockwise angle A around the shaft, and now straight-bar 4, except being subject to gravity mg, is also subject to the effect of level inertial force ma left, can be obtained by moment equilibrium condition: mg(L/2) sinA=ma(L/2) cosA, i.e. acceleration a=gtanA.The angle A turning over according to straight-bar 4 can obtain horizontal acceleration a, and the accekeration on acceleration scale 6 is demarcated by a=gtanA.
Before measurement, if acceleration pointer 5 has deviation with " 0 " the groove position at acceleration scale 6 middle parts, the leveling serew 7 of adjustable frames 1 below returns to zero.
