Horizontal-casting sectional demonstration experimental device and experimental method thereof

Abstract

The invention discloses a horizontal-casting sectional demonstration experimental device. The horizontal-casting sectional demonstration experimental device comprises an upper vertical plate, a lower vertical plate, high-low extensible rods connecting the upper vertical plate with the lower vertical plate, a horizontal-casting motion guide rail, a horizontal motion guide rail, a base, a photoelectric sensor device, an electromagnetic coil device, a display screen control panel, a horizontal motion positioning sensor, a horizontal-casting motion positioning sensor and a vertical motion positioning sensor. Through line electric treatment and a displacement sensor, respective motion time and corresponding displacement (in the height and horizontal direction) of horizontal-casting motion, horizontal motion and vertical motion can be fed back to and displayed on the display screen control panel at any time; all displacement data can be directly read from corresponding areas of the experimental device; actual process demonstrative experiments and live-action exploration operations (true image visualization of experiments) can be optionally performed on the three motion respectively by the experimental device, corresponding digitalization can be performed instantly or at any time for accurate measurement, and an experimental method and the experimental device for exploring and analyzing horizontal casting are provided through sufficient integration.

Description

Technical field [0001] The invention relates to a teaching demonstration tool, in particular to a flat throwing decomposition demonstration experiment device and an experiment method thereof. Background technique [0002] The current technical level of the demonstrator: the first type of horizontal throwing and vertical falling instrument only compares the two movements of horizontal throwing and vertical falling, and there is a serious lack of one of the uniform motions for simultaneous comparison experiments, and the comparison method uses the comparison sound method, which is extremely unstable Unobvious methods such as inconspicuous and unobvious methods; the second instrument either just captures a certain instantaneous state during the above-mentioned motion process and records the corresponding traces, and the result of the experimental process obtained is more realistic and credible. However, the accuracy of the experimental results is low, and the subsequent exploration ...

Problems solved by technology

[0002] The current technical level of the demonstration instrument: the first type of flat throwing and vertical falling instrument only compares the movements of flat throwing and vertical falling, and is seriously lacking in one of the uniform motions for simultaneous comparison experiments, and the comparison method is extremely unstable due to the comparative sound method and non-obvious bad methods; the second instrument either only captures a certain transient state in the above-mentioned movement process and records the traces correspondingly, and the experimental process results obtained are more authentic and credible

However, the accuracy of the experimental results is low, and the follow-up exploration and processing of the experiment are more cumbersome and many other unreasonable experimental weaknesses; Movement displacement cannot be effectively and directly captured and measured, that is, the experimental process of the movement lacks a sense of reality or lacks fidelity, or although there is an experimental method to simultaneously determine time and displacement through corresponding displacement sensors, it can only The indirect ex
