Description

利用片状弹簧的轴向振动减振器
本发明涉及使用片状弹簧的轴向振动减振器，用它作为支撑结构的支架，例如支撑大型引擎，建筑物的空调设备，印刷机械，桥梁，还有其它多种用途。本发明的轴向振动减振器具有高负载量，刚度和减振力易于控制，而且耐久性长。因此，本发明的振动减振器与常规的橡胶减振器相比，在长时期内能够更有效更经济地对轴向振动进行减振。
橡胶减振器非常便宜，并广泛用于弹性支架。但是，当将它用于高温环境，并经过长时间后，其弹性消失，由此，它的静力学和动力学特征产生变化。换句话说，其存在着耐久性问题。橡胶的刚度小于钢材，因此橡胶减振器不适于用来支撑高负载。近来，提出采用流体支架，即在橡胶减振器中设置填充油料的空间的修改方案增大减振力。而且，橡胶弹性支架且有非线性动力学特征，因此不容易控制这种支架的刚度和减振力。所以，很难设计出最佳的减振系统。
本发明的目的是提供一种能在高温条件下使用的、具有高负载量，很容易控制其刚度和减振力的轴向振动减振器。
按照本发明的利用片状弹簧的轴向振动减振器，其片状弹簧沿径向安装在外运动元件和内固定元件之间。
理论分析结果表明，本发明减振器的减振力大于橡胶减振器，而且本发明减振器的动力学特征呈线性特性。因此，很容易设计出最佳减振系统。
图1是本发明的内部截面的视图。
图2是本发明的侧剖面的视图。
图3是表示另一种类型的片状弹簧板垛的视图。
图1～3中用代号表示的部件如下所述：
1：片弹簧        4：油槽
2：外运动元件    5：密封元件
3：内固定元件    6：内部流体空间
如图1和2所示，本发明的轴向振动减振器由若干片弹簧的板垛和内部流体空间组成。由片弹簧弹性支撑着外运动元件。所述片弹簧沿径向安装在内固定元件上。由片弹簧的数量、几何尺寸(即，厚度、宽度和长度)及材料，还有片弹簧板垛的数量决定支撑力。因为可以控制片弹簧板垛的弹性支撑力，安装在本发明的振动减振器上的机械的固有频率很容易得到控制。当固有频率得到控制时，使固有频率远离驱动频率就能大大加强机械的稳定性。
如图2所示，由片弹簧板垛1将内部流体空间6分为上、下空间。油通过槽4流动，所述槽4位于片弹簧板垛1的两侧。外运动元件2和内固定元件3之间的相对运动导致内部流体空间6的体积变化。当空间6的体积变化时，上、下空间出现压力差。此压力差迫使油流动，因此由槽4的不同尺寸和油粘度控制减振力。当空间6的体积变化时，上、下空间出现压力差。此压力差迫使油流动，因此由槽4的不同尺寸和油粘度控制减振力。
理论分析结果表明，本发明减振器的减振力大于橡胶减振器，而且本发明减振器的动力学特征呈线性特性。因此，很容易设计出最佳减振系统。
