模拟地震时建筑物振动模拟工作台设计

摘要：本设计提出一套简易的模拟地震时建筑物振动模拟工作台的设计，其设计原理是通过机械传动系统传动动力来带动模拟建筑物振动从而能够让人们直观的观察建筑物在地震时的振动状态。这套设计主要有变速系统，动力系统，机械传动系统，建筑物振动系统三个部分组成.

该模拟系统主要是通过变速系统来控制电机的转速来模拟地震不同的振动幅度，再通过机械传动系统来传动动力到建筑物振动系统使得建筑物振动，在建筑物振动系统中，主要是由一个抗震建筑物和一个不抗震建筑物组成，通过对比能够更好地更加直观的在人们面前展现建筑物在地震时的状态。

该系统虽然没有电液伺服地震模拟振动台那么精确，能够验证很多东西，但是它可以作为让人们观赏，让人们对地震时建筑物振动的初步了解的很好的平台，而且它的成本比较低，经济实用。本设计在符合设计要求的基础上就部分关键部件进行了相关功能和结构的设计。

When simulating seismic building vibration simulation table design abstract：This paper proposes a set of simple and easy the design of the building when the earthquake vibration simulation workbench, its design principle is driven by mechanical transmission system dynamics simulation vibration so that they can make people visual observation of the building in a state of vibration during the earthquake. This design mainly has variable speed system, power system, mechanical drive system, building vibration system of three parts.

Mainly through the simulation system of variable speed system to control the motor speed to simulate earthquake vibration amplitude, again through the mechanical transmission system to drive power to the vibration system makes the building vibration, in the building vibration system, mainly by a seismic building and not a earthquake-resistant buildings, by comparing to better more intuitive show in front of the building during an earthquake.

While the system is not so precise electro-hydraulic servo vibration table, to verify a lot of things, but it can be used as a let people admire, let people preliminary understanding of the building when the earthquake vibration of a good platform, and its cost is lower, economical and practical. This design in accordance with the requirements of the design on the basis of some key components for the design of the related function and structure.

Key words:economic and practical,earthquake
