The invention discloses a flat opening mechanism with a moving pair; the flat opening mechanism comprises a connecting rod mechanism with the moving pair as well as a pushing rod and swinging rod mechanism, wherein the pushing rod and swinging rod mechanism comprises a pull rod; two ends of the pull rod are respectively hinged with a first swinging rod and a second swinging rod; the first swinging rod and the second swinging rod are respectively hinged with a third swinging rod and a fourth swinging rod; the third swinging rod and the fourth swinging rod are respectively hinged with a first connecting rod and a second connecting rod; the first connecting rod and the second connecting rod are both hinged with a heald frame; and the pushing rod and swinging rod mechanism is connected with the connecting rod mechanism with the moving pair by the pull rod. According to the invention, in order to adapt to high rotation speed of 900-1000 rpm of the traditional air jet loom, the flat opening mechanism with the moving pair is designed from an angle of high speed of the loom; a cam opening mechanism is replaced with the connecting rod mechanism with the moving pair, so that the damages of other parts of the air jet loom are avoided when vibration sources such as a cam and a cam rotor are eliminated.

The invention belongs to the field of music instruments, and particularly relates to a soft wind instrument. The soft wind instrument comprises a suona reed, a gaseous disk, a core, a suona bar, and a sauna bowl. The sauna bowl has a soft body, nanoparticles are embedded onto the inner surface of the soft body, and the nanoparticles are copper or nickel nanoparticles or ceramic nanoparticles. According to the invention, by changing the traditional material of the instrument, the position of the vibration source still maintains enough strength and toughness to ensure that the physical properties of the sound source remain unchanged. The traditional musical instrument science and physical material science knowledge are combined, so that a wind instrument made of soft materials can achieve the same acoustic effect as a wind instrument made of wood or metal materials, and the balance between ranges, timbre, tone and volume are fused and united. Meanwhile, the 'soft instrument' is small and convenient to carry, and can be unfolded when in use and folded or coiled for storage when not in use.

The invention discloses a gyroscope damping effect test device which comprises a stepping motor, a coupler body, a magnet block, a speed increaser, a coupler, a gyroscope, a bearing, a motor end cover, a multi-section sleeve, a motor flange plate, a pair of speed increaser flange plates, a pair of bearing flange plates, a gyroscope sleeve, acceleration sensors, a charge amplifier and an upper computer. The speed regulator regulates the rotating speed of the stepping motor to drive the upper end of the upper magnetic coupling body to rotate quickly, an upper magnet block is embedded in the lower end of the upper magnetic coupling body, and a lower magnet block is embedded in the lower end and the upper end of the lower magnetic coupling body. A motor output shaft and a speed increaser low-speed shaft are driven to synchronously rotate through a magnetic coupling effect; the speed increaser increases the output rotating speed, a high-speed shaft transmits a rotating force to the gyroscope through the coupler to drive the gyroscope to rotate at a high speed, a left-end vibration source horizontally acts at the lower end of the device, and the two acceleration sensors conduct acceleration on the gyroscope sleeve to collect vibration signals.

The earthquake experience platform is driven by a crank-connecting rod mechanical vibration source. In the figure, 1 is the top frame of the platform, 2 is the center column, 3 is the driving mechanism in the X direction, 4 is the driving mechanism in the Y direction, and 5 is the driving mechanism in the Z direction. During operation, the X-direction vibration source, the Y-direction vibration source, and the Z-direction vibration source start at the same time, and the X-direction vibration source drives the center column 2 and the platform top frame 1 to reciprocate along the X direction, and the Y-direction vibration source is driven by the Y-direction telescopic rod. The platform support reciprocates along the Y direction, and the Z-direction vibration source drives the platform top frame to reciprocate along the vertical direction through the L-shaped swing frame and the double ten-byte mechanism. The platform support simultaneously performs horizontal X-direction, horizontal Y-direction and vertical composite Movement and movement in all directions do not interfere with each other, increase the vibration frequency of the platform, and increase the authenticity of the earthquake experience.
