Description

阻尼装置
技术领域
本发明涉及一种阻尼装置,具体涉及一种间隙可调式变刚度微粉弹性碰撞阻尼器。
背景技术
碰撞阻尼是一种被动控制,它的工作原理是利用冲击器(金属小球)在振动过程中与主系统发生碰撞,从而来控制碰撞响应。
碰撞阻尼器是一种通过阻力来减少运动幅度、损耗运动能量、达到减振效果的器具;振动阻尼器有个很明显的特点就是它不需要外界的能量输入就可以通过自身的特殊性达到减振效果,这样就能够在极端恶劣的条件下正常工作而取得明显效果。传统的碰撞阻尼器是在密闭的腔体内加入球形冲击器(球体),在高频振动时球形冲击器能够不断冲击容器壁两端,由于冲击作用消耗掉系统的能量,故其冲击力的大小直接决定了阻尼器的减振效果。
但是,迄今为止,不可变间隙比、固定刚度(一阻尼器一固定弹簧装置的构成)以及冲击器(金属小球)的运动规律的不可视性使得阻尼器成为一阻尼器一使用功能,妨碍了阻尼器的灵活运用、也妨碍了对阻尼器冲击器(金属小球)的观察,也增加了阻尼器在使用过程中的成本。
发明内容
本发明是为了解决上述问题而进行的,目的在于提供一种间隙可调式、刚度可变式、微粉颗粒弹性碰撞的阻尼装置。该阻尼装置,达到了过程可视、间隙比可调节、以及弹簧装置刚度可变换的目的。
本发明提供了一种阻尼装置,具有这样的特征,包括:底座,用以支撑碰撞阻尼器;碰撞阻尼器,吸收振动能量。其中,底座包括:底座本体,通过滑轨、弹簧装置支撑碰撞阻尼器;以及,滑轨,可拆卸地固定在底座本体上,用于滑动支撑碰撞阻尼器。碰撞阻尼器包括:阻尼器壳体,包括:横断面为圆形的壳身与两端的封头;至少一个的弹簧装置,包括弹簧和固定端;弹簧的一端可拆卸地固定在封头的外侧的固定端上,弹簧的另一端可拆卸地固定在底座本体的固定端上;至少一个的活塞体,设置于阻尼器壳体内、一侧用螺杆连接到封头外呈可调节状态;球体,设置于阻尼器壳体内,通过与封头、活塞、粉末颗粒碰撞吸收振动能;以及,粉末颗粒,与球体一同设置于壳体内,与球体、壳身、封头碰撞吸收振动能量。
在本发明提供的阻尼装置中,还可以具有这样的特征:其中,壳身是透明材料制成的。
在本发明提供的阻尼装置中,还可以具有这样的特征:其中,透明材料是透明有机玻璃。
在本发明提供的阻尼装置中,还可以具有这样的特征:其中,底座、滑轨、封头、活塞体、弹簧装置的固定端、球体、以及粉末颗粒是用金属材料制成的。
在本发明提供的阻尼装置中,还可以具有这样的特征:其中,金属材料为铝合金。
发明的作用与效果
根据本发明所涉及的阻尼装置,因为可调节的活塞体和可拆卸弹簧装置的使用,所以,本发明的阻尼装置具有可调间隙比和可调刚度的功能,可实现不同间隙比和不同刚度要求的阻尼振动要求。
附图说明
图1是本发明的实施例中阻尼装置的剖视图。
图2是本发明的实施例中阻尼装置的俯视图。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,以下实施例结合说明书附图对本发明的阻尼装置作具体阐述。
图1是本发明的实施例中阻尼装置的剖视图。图2是本发明的实施例中阻尼装置的俯视图,辅助说明图1。
如图1、图2所示,本发明的阻尼装置100,包括:底座10,用以支撑碰撞阻尼器20,碰撞阻尼器20,用以吸收振动能量;其中,底座10包括:底座本体11,通过滑轨12和可拆卸地固定在底座本体11上的至少一个的弹簧装置13支撑碰撞阻尼器20;以及,滑轨12,可拆卸地固定在底座本体11上,用于滑动支撑碰撞阻尼器20。
碰撞阻尼器20包括:横断面为圆形的壳身21与封头22组成的阻尼器壳体,弹簧装置13可拆卸地固定在封头22外侧;至少一个的活塞体23,设置于阻尼器壳体内,一侧用螺杆24连接到封头22外呈可调节状态;球体25,设置于阻尼器壳体内,通过与封头22、活塞23、粉末颗粒26碰撞吸收振动能;以及,粉末颗粒26,与球体25一同设置于壳体内,与球体25碰撞吸收振动能。
根据本发明的阻尼装置100,通过调节活塞体23的位置和拆卸更换弹簧装置13的弹簧,实现不同间隙比和不同刚度要求的阻尼振动要求。
根据本发明的阻尼装置100中,壳身21是透明材料制成的,例如透明有机玻璃。
还有,底座本体11、滑轨12、封头22、活塞体23、弹簧装置13的固定端、球体25、以及粉末颗粒26是用金属材料制成的,例如铝合金。
根据本发明的阻尼装置100,不仅能够通过调节活塞体的位置和拆卸更换弹簧装置,实现不同间隙比和不同刚度要求的阻尼振动要求,还可以通过透明壳身21看到球体25的振动特点,方便研究的进行。
实施例的作用与效果
根据本发明实施例的阻尼装置,因为碰撞阻尼器壳体的腔内设计成了活塞形式,可以通过螺纹杆调节活塞位置改变球体运动空间的大小,所以,实现了间隙比的可调性;再因为碰撞阻尼器壳身为透明材料制成,所以,该阻尼装置用于碰撞研究试验时,能够清楚地观察球体的运动及撞击情况;又因为碰撞阻尼器的弹簧装置是可拆卸调换的,所以,该阻尼装置可用于不同刚度要求的阻尼试验,扩大了同一台阻尼装置的使用范围。
本发明的阻尼装置,结构设计精巧、简单方便易操作、灵活性强应用面宽,且一台阻尼装置能完成多种刚度要求的阻尼试验。
本发明的阻尼装置,因为整个系统的抗冲击性能好,能在恶劣的环境条件下正常工作,再通过选用铝合金材料制作,达到了质轻稳定、耐磨性好的使用要求。
上述本发明的实施例,是本发明的优选案例,并不用来限制本发明的保护范围。
