Embodiment Construction

[0058] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0059] see figure 1 , a lunar instrument for simulating lunar libration and lunar phase changes, comprising:

[0060] base1;

[0061] The bow-shaped support 2 is in the shape of a bow and is fixedly arranged on the upper end surface of the base 1;

[0062] The lunar instrument shell 3 is a transparent spherical structure with a spherical cavity 3.1 inside, and the lunar instrument shell 3 is fixedly connected to the bow-shaped bracket 2;

[0063] The shading plate 4 has a hemispherical structure, has a spherical surface 4.1 and a plane 4.2, and is built in the spherical cavity 3.1 of the lunar instrument shell 3, and the plane 4.2 of the shading plate 4 is fixedly...

Abstract

The invention provides a lunar instrument for simulating the lunar balance and the moon phase change, comprising: a base; a bow-shaped support fixedly arranged on the upper surface of the base; a lunar instrument shell with a spherical cavity inside, and the lunar instrument shell is fixedly connected with the arc-shaped support The shading plate is built in the spherical cavity of the lunar instrument shell, and the plane of the shading plate is fixedly connected with a coaxial device; the Z-shaped transmission shaft is connected to the outer shaft at one end, and the other end is connected to the first drive motor through the reduction gearbox Transmission connection, the first driving motor is placed in the base; the second driving motor is placed in the spherical cavity of the lunar instrument shell, and is connected to the inner shaft by transmission; the simulated light source is fixed on the plane of the visor and placed on the base The electrical connection to the power supply inside. It can realize more accurate calculation of the display range of the moon phase on the real three-dimensional spherical surface, more intuitive and realistic display of the moon phase effect on the three-dimensional lunar instrument, and better serve the application and research of lunar science.

Description

technical field [0001] The invention relates to the field of lunar and planetary space information, in particular to a lunar instrument for simulating lunar libration and lunar phase changes. Background technique [0002] The moon phase refers to the name in astronomy for the part of the moon seen on the earth illuminated by the sun. The moon moves around the earth, causing the relative positions of the sun, the earth, and the moon to change regularly in a month. Because the moon itself does not emit light and is opaque, the visible luminous part of the moon is the part that reflects sunlight. Only the part of the moon directly illuminated by the sun can reflect sunlight. People see the part of the moon directly illuminated by the sun from different angles, which is the source of the moon phase. The moon phase is not caused by the earth covering the sun (this is a lunar eclipse), but because people can only see the part of the moon that is illuminated by the sun and glows...
