Pendulum clock type velvet effect experimental apparatus

Abstract

The invention discloses a pendulum clock type velvet effect experimental apparatus which comprises a base (1), a swing rod (2), a swing hammer supporting plate (3), a swing rod connection hole (4), a fish thread frame (5), a fish thread (6), an adjustable knob (7), a knob rail (8), a weight box (10) and an operator hand placing area (13). The lower end of the fish thread frame (5) is perpendicularly fixed on the weight box (10), the swing hammer supporting plate (3) is perpendicularly fixed at the upper end of the fish thread frame (5), the swing rod (2) is fixed on the upper surface of the swing hammer supporting plate (3), the base (1) is connected with the swing rod (2), the fish thread (6) is fixed on the fish thread frame (5) through the adjustable knob (7), and the swing hammer supporting plate (3) is hung on the base (1) through the swing rod (2) and the swing rod connection hole (4). According to the pendulum clock type velvet effect experimental apparatus, an external drive is not needed, and an operator can feel the velvet effect in a driven mode through swing like a pendulum.

Description

technical field [0001] The invention relates to a "velvet" effect experimental device, in particular to an experimental device which uses potential energy as a driving force to help operators perceive the "velvet" effect in a passive manner through the swing of a pendulum. Background technique [0002] The "velvet" effect is a tactile illusion phenomenon, which refers to the phenomenon that the operator's skin feels "velvet" through the movement of the physical device, but in fact the skin does not touch any "velvet" material. The "velvet" effect is derived from Japanese folk games, and this effect belongs to the category of tactile display technology. [0003] Tactile display technology is a cutting-edge technology that studies how to make human skin obtain image and text information in a tactile way. It is generally believed that the tactile display technology originated from the Braille characters with a concave and convex feeling, and the technical research began in the...

Problems solved by technology

The device has certain novelty, but there are several deficiencies in the following aspects: 1) The distance between the double rows of fish silk lines cannot be adjusted freely; 2) The reciprocating motion of the experimental device is horizontal, which cannot meet the requirements of non-horizontal experiments; 3 ) cannot couple vibrations on the fish silk line to study the impact of external forced vibrations, especially the "standing wave" effect, etc. on the "velvet" effect

[0006] At present, there is no patent related to the velvet effect, and there is no pendulum-type velvet effect experimental device that can be coupled with external forced vibration, can adjust the spacing between fish silk lines arbitrarily, and does not require external drives.
