Description

一种可调摆式多维低频文物减震装置An adjustable pendulum type multi-dimensional low-frequency cultural relic shock absorber

技术领域technical field

本发明涉及一种文物减隔震装置,属于可移动文物的安全防护及动力分析领域。The invention relates to a cultural relic anti-shock isolation device, which belongs to the field of safety protection and dynamic analysis of movable cultural relics.

背景技术Background technique

可移动文物是世界文化遗产的重要组成部分,具有极其重要的文化、历史价值,保护意义重大。对这些文物的保护,不仅有防火、防盗要求,还应有防震要求。大量震害表明,浮放文物在地震烈度为3~4度时,就有可能产生严重破坏。由于地震的不可预见及巨大的破坏性,使得对这些文物采取及时有效的防震措施迫在眉睫。Movable cultural relics are an important part of world cultural heritage, with extremely important cultural and historical value, and protection is of great significance. The protection of these cultural relics requires not only fire protection and anti-theft requirements, but also earthquake resistance requirements. A large number of earthquake damage shows that floating cultural relics may cause serious damage when the seismic intensity is 3 to 4 degrees. Due to the unpredictability and great destructiveness of the earthquake, it is extremely urgent to take timely and effective anti-seismic measures for these cultural relics.

从馆藏浮放文物隔震装置的研发现状来看,国内方面在此方面严重不足,而国外方面如日本、美国、意大利等国家已普遍推广使用不同类型文物隔震装置以实现基于先进技术的文物防震保护。滚轮式、滚轴式、滚珠式、滑块式、摩擦摆式等不同类型隔震装置得以研发,空气弹簧、恒力弹簧、磁石、形状记忆合金等不同类型隔震材料得以应用,使得文物隔震装置的开发前景广阔。然而从文物隔震装置的隔震效果来看,实现构造简单、小容积、低传导比(文物的响应加速度峰值与输入地震波加速度峰值之比)及避免竖向摇摆,并保证隔震装置的可靠性、耐久性仍是一个重要的课题。Judging from the status quo of the research and development of seismic isolation devices for floating cultural relics in the collection, there is a serious shortage in this area in China, while foreign countries such as Japan, the United States, Italy and other countries have generally promoted the use of different types of seismic isolation devices for cultural relics to realize cultural relics based on advanced technology. Shock protection. Different types of vibration isolation devices such as roller type, roller type, ball type, slider type, and friction pendulum type have been developed, and different types of vibration isolation materials such as air springs, constant force springs, magnets, and shape memory alloys have been applied, making cultural relics isolated The development prospect of the seismic device is broad. However, from the perspective of the seismic isolation effect of the cultural relics isolation device, it is necessary to achieve a simple structure, small volume, low conduction ratio (the ratio of the peak response acceleration of the cultural relic to the peak acceleration of the input seismic wave), avoid vertical swing, and ensure the reliability of the isolation device. Performance and durability are still important issues.

现有的文物隔震装置大都以水平隔震为主,而竖向地震分量往往占重要地位。从水平恢复力部件角度讲,传统的弹簧需要竖向双层设置方可实现水平任意向隔震。而基于重力恢复力的曲面滚轮或滚珠装置则很容易发生由于水平地震力过大而造成部件飞出的问题。从竖向恢复力部件角度讲,传统的弹簧由于静挠度过大而容易产生竖向弯曲问题,且部件构造复杂,占据竖向空间较大。因此,需要研发制造简便、机理明确、效果明显的多维文物减震装置。Most of the existing seismic isolation devices for cultural relics are mainly horizontal isolation, while the vertical seismic component often plays an important role. From the perspective of horizontal restoring force components, traditional springs need to be vertically double-layered to achieve horizontal vibration isolation in any direction. However, the surface roller or ball device based on the gravity restoring force is prone to the problem of parts flying out due to excessive horizontal seismic force. From the perspective of vertical restoring force components, traditional springs are prone to vertical bending problems due to excessive static deflection, and the components are complex in structure and occupy a large vertical space. Therefore, it is necessary to develop and manufacture a multi-dimensional cultural relic shock absorbing device that is simple to manufacture, has a clear mechanism, and has obvious effects.

现有的文物隔震装置大都以水平隔震为主,而竖向地震分量往往占重要地位。从水平恢复力部件角度讲,传统的弹簧需要竖向双层设置方可实现水平任意向隔震。而基于重力恢复力的曲面滚轮或滚珠装置则很容易发生由于水平地震力过大而造成部件飞出的问题。从竖向恢复力部件角度讲,传统的弹簧由于静挠度过大而容易产生竖向弯曲问题,且部件构造复杂,占据竖向空间较大。基于此,本发明试图通过可调摆式文物低频减震装置的研发解决上述问题。Most of the existing seismic isolation devices for cultural relics are mainly horizontal isolation, while the vertical seismic component often plays an important role. From the perspective of horizontal restoring force components, traditional springs need to be vertically double-layered to achieve horizontal vibration isolation in any direction. However, the surface roller or ball device based on the gravity restoring force is prone to the problem of parts flying out due to excessive horizontal seismic force. From the perspective of vertical restoring force components, traditional springs are prone to vertical bending problems due to excessive static deflection, and the components are complex in structure and occupy a large vertical space. Based on this, the present invention attempts to solve the above-mentioned problems through the research and development of an adjustable pendulum-type cultural relic low-frequency damping device.

所述上连杆与下连杆,选用轻质且强度高的材料,如金属基复合材料;上连杆长度与下连杆长度之比大于2。The upper connecting rod and the lower connecting rod are made of light and high-strength materials, such as metal matrix composite materials; the ratio of the length of the upper connecting rod to the length of the lower connecting rod is greater than 2.

所述可调式配重块,材料选用铅合金、锌合金、铸铁,所述可调式配重块长宽与所述钢化玻璃箱相同,所述可调式配重块用所述锚固螺栓固定于所述钢化玻璃箱底部,可以通过改变所述可调式配重块数量来改变质量大小。The material of the adjustable counterweight is lead alloy, zinc alloy and cast iron, the length and width of the adjustable counterweight are the same as the tempered glass box, and the adjustable counterweight is fixed to the The bottom of the tempered glass box can change the quality by changing the quantity of the adjustable counterweight.

所述钢化玻璃箱使用全钢化玻璃,所述钢化玻璃箱内置摩擦垫层。The tempered glass box uses fully tempered glass, and the tempered glass box has a built-in friction cushion.

所述碟形弹簧可通过改变簧片数量来改变刚度。The stiffness of the disc spring can be changed by changing the number of reeds.

The tempered glass box is hinged with the upper link and the lower link, and swings in the horizontal direction at a low frequency. Resist the earthquake action in the horizontal direction, and then achieve the purpose of earthquake isolation.

本发明采用单摆和倒摆并联隔振系统原理,钢化玻璃箱和可调质量块质量和为m,钢化玻璃箱上端与长为L1上连杆铰接,构成单摆,称之为正摆;可调配重块下端通过与一长为L2的下连杆铰接,下连杆下端与刚度为Ks的碟形弹簧铰接,构成倒摆。单摆与倒摆通过钢化玻璃箱和可调配重块并联在一起,杆长比Lr=L1/L2,碟形弹簧初始压缩量为ΔL,系统处于平衡位置时,系统刚度为: K ( 0 ) = mg L 1 - K s ΔL L 1 ( 1 + L r ) , 若令K(0)=0,得 ΔL = Mg K s ( L r + 1 ) , ΔL = Mg K s ( L r + 1 ) 时,隔振系统在水平方向刚度为0,隔振系统达到低频隔振作用,随着Lr的减小,系统可在距平衡点更大范围内具有较低的刚度,适用于外界振动振幅较大的情况。随着Ks的减小,系统具有低刚度的范围增大。可通过合理选取Lr和Ks的值,使隔振系统固有频率足够低,达到低频隔振的目的。The present invention adopts the principle of the parallel vibration isolation system of the single pendulum and the inverted pendulum, the mass sum of the toughened glass box and the adjustable mass block is m, the upper end of the toughened glass box is hinged with the upper link whose length is L1 to form a single pendulum, which is called a positive pendulum ; The lower end of the adjustable counterweight is hinged with a lower link with a length of L2, and the lower end of the lower link is hinged with a disc spring with a stiffness of Ks to form an inverted pendulum. The simple pendulum and the inverted pendulum are connected in parallel through a toughened glass box and an adjustable counterweight. The rod length ratio L r = L 1 /L 2 , the initial compression of the disc spring is ΔL, and when the system is in the equilibrium position, the system stiffness is: K ( 0 ) = mg L 1 - K the s Δ L L 1 ( 1 + L r ) , If K(0)=0, we get ΔL = Mg K the s ( L r + 1 ) , when Δ L = Mg K the s ( L r + 1 ) When , the stiffness of the vibration isolation system in the horizontal direction is 0, and the vibration isolation system achieves the effect of low frequency vibration isolation. With the decrease of L r , the system can have a lower stiffness in a larger range from the equilibrium point, which is suitable for the external vibration amplitude larger case. As K s decreases, the range in which the system has low stiffness increases. By selecting the values of L r and K s reasonably, the natural frequency of the vibration isolation system is low enough to achieve the purpose of low frequency vibration isolation.

与现有技术相比,本发明具有如下有益效果。Compared with the prior art, the present invention has the following beneficial effects.
