摘要：本次设计主要是对小型振动实验台的结构设计和对振动台测试系统的设计，振动台的设计是振动情况的控制和优化机械结构，从而保证振动台具有很好的动态特性和环境适合度，进而提高设备的整体性能，是振动台发挥出它本身的作用，不会产生不必要的误差。振动测试系统是测试的主要流程，振动台是基本，测试是主要，测试系统包括传感器的搭建，实验的进行，只有良好的测试系统，才能得出最后的测试结果。79854

     振动实验的主要意义是防止在运输和使用物体的过程中产生的振动和不必要的外在振动是物体收到破坏，从而产生巨大的损失，振动实验还可以测试出物体的其他性能。振动测试在近年中有着很多用处，由其在航天航空中，一点地方产生不必要的振动，那么产生的损失不只只是经济，还有生命，这都凸显出振动测试的重要性。小型振动台是振动测试实验中主要的设备，它包括振动台设计，传感器选择，测试系统的组成搭建等等。

Design of Small Vibration Test Bench and Test System

Abstract: This design is mainly for the design of small vibration test bed design and vibration table test system design, vibration table design is the vibration control and optimization of mechanical structure, so as to ensure that the vibration table has a good dynamic characteristics and the environment Fit, and thus improve the overall performance of the device, the vibration table to play its own role, will not produce unnecessary errors。 Vibration test system is the main process of testing, shaking table is the basic, the test is the main test system, including the sensor set up, the experiment carried out, only a good test system, in order to draw the final test results。

     The main significance of the vibration experiment is to prevent the vibration in the process of transporting and using the object and unnecessary external vibration is the object to receive damage, resulting in huge losses, vibration experiments can also test the other properties of the object。 The vibration test has a lot of usefulness in recent years, and it produces unnecessary vibration in aerospace, and the loss is not just the economy, but also the life, which highlights the importance of vibration testing。

The small vibration table is the main equipment in the vibration test experiment。 It includes the vibration table design, the sensor selection, the composition of the test system and so on。
