Embodiment Construction

[0019] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0020] The invention provides a tension integral vibration isolator with adjustable frequency.

[0021] The vibration isolator is composed of n X-shaped tensioned overall structures in different pre-tensioned states in series; the X-shaped overall tensioned structure consists of a beam member 1, a spring, and a rod member 2, wherein the beam member 1 is along the horizontal direction Arrangement, the springs are arranged along the vertical direction, the beam members 1 and the springs are alternately connected to form a rectangular outer frame, and the rod members 2 are arranged along the diagonal direction of the rectangular outer frame.

Abstract

The invention provides a frequency-adjustable tensegrity vibration isolator, and belongs to the technical field of vibration control. The vibrator is formed by connecting multiple X-shaped tensegritystructures in different pre-stretched state in series. Each X-shaped tensegrity structure is formed by two beams, two springs and two rods, wherein the beams and the springs are alternately connectedin the horizontal direction and the vertical direction respectively to form a rectangular frame, and the rods are arranged in the diagonal direction of the rectangular frame. The springs and the rodsare connected with the upper beams and the lower beams through spherical hinges. The different X-shaped tensegrity structures are connected in series through the upper beams and the lower beams. According to the vibration isolator, the number and pre-stretched state of the X-shaped tensegrity structures can be set according to actual needs, different stretching force functions are exerted to turnon and off a vibration isolating function, and the vibration isolating frequency range is adjusted when the vibration isolating function is turned on. The frequency-adjustable tensegrity vibration isolator is simple and reasonable in structure, and the special mechanical property of the tensegrity structures is utilized for achieving turning on of the vibration isolating function and frequency adjustment.

Description

technical field [0001] The invention relates to the technical field of vibration control, in particular to a frequency-adjustable tension integral vibration isolator. Background technique [0002] The tensegrity structure is a kind of light-weight, grid-like spatial structure system, which is formed by interconnecting pre-stretched rope units and pre-compressed rod units. The tensegrity structure has the advantages of high material utilization rate, foldable / unfoldable configuration, wide-ranging adjustment of mechanical properties, and easy assembly of the monolithic structure. However, due to many reasons, tensegrity structure is rarely used as a mainstream design method in current engineering structure design. The few practical applications of tensegrity structures in engineering practice are mainly due to poor understanding of the mechanical behavior of these systems. Therefore, utilizing the special mechanical properties of the X-shaped tensegrity structure, the inven...
