Description
技术领域 technical field
本发明涉及振动工作台装置，尤其涉及一种倾角可调的振动工作台装置。 The invention relates to a vibration table device, in particular to a vibration table device with an adjustable inclination angle.
背景技术 Background technique
振动试验现在已被广泛应用于各类军用及民用领域，包括航空航天、地震模拟、 交通运输等领域。试件的可靠性与否往往关系到整个机械系统的性能，因此在振动试验中，我们希望能够模拟试件的真实安装环境及其工作环境。工作台是安装支撑试件的主要装置，能够将振动台主轴的振动传递给试件，从而模拟试件的真实工作环境，由于目前市场上主要的振动工作台振动方向均是单方向的，包括水平振动方向工作台和垂直振动方向工作台，工作台本身无法对试件的安装角度进行调节，因此无法模拟一些试件的复杂安装环境，尤其是模拟倾斜安装环境，因此不可避免影响试件的可靠性分析。本发明针对一种倾角可调的振动工作台，所设计的工作台不仅可以根据试件的真实安装环境对试件的安装角度进行调节，且能在试件的振动实验过程中通过对导轨的位移调节实现试件的倾角自动调节，安全可靠，目前为止，国内还未见振动工作台上通过采用丝杠导轨与球铰配合运动对工作台进行倾角调节的装置。 Vibration tests are now widely used in various military and civilian fields, including aerospace, earthquake simulation, transportation and other fields. The reliability of the test piece is often related to the performance of the entire mechanical system, so in the vibration test, we hope to simulate the real installation environment and working environment of the test piece. The workbench is the main device for installing and supporting the test piece. It can transmit the vibration of the main shaft of the vibrating table to the test piece, thereby simulating the real working environment of the test piece. Since the vibration direction of the main vibrating worktables on the market is unidirectional, including Horizontal vibration direction workbench and vertical vibration direction workbench, the workbench itself cannot adjust the installation angle of the specimen, so it cannot simulate the complex installation environment of some specimens, especially the simulation of the inclined installation environment, so it will inevitably affect the installation angle of the specimen. reliability analysis. The present invention is aimed at a vibrating workbench with adjustable inclination angle. The designed workbench can not only adjust the installation angle of the test piece according to the real installation environment of the test piece, but also can pass the vibration of the guide rail during the vibration experiment process of the test piece. The displacement adjustment realizes the automatic adjustment of the inclination angle of the test piece, which is safe and reliable. So far, there is no device on the vibrating workbench that uses the screw guide rail and the ball hinge to coordinate the movement to adjust the inclination angle of the workbench.
