下面就这几个方面实现的功能进行介绍

The functions described below are introduced in this paper.

一、液压脉冲系统

Hydraulic impulse system

系统框图：

System block diagram:

因为我们知道，液压系统是实现压力脉冲模拟以及压力控制的基础，主要设计难点是压力的控制，压力上升的速率，以及测量件故障损坏告知和自动处理。

Because we know that the hydraulic system is the basis of the pressure pulse simulation and pressure control, the main design difficulty is the pressure control, the pressure rise rate, as well as the measurement of the fault damage to inform and automatic processing.

在设计压力控制中，我们采用变排量的液压泵以及电子溢流控制阀等部件组成的回路进行高压的控制，低压由电子泄流阀等组成的低压控制回路。但是压力上升的速度是由于压力泵的排量决定的。（我们知道，压力升高，测量件将会变形，容积会增进。增进的压力和容积有个相对应的关系）因此，在最快速的脉冲试验中，在多短的时间中，注入测试件的液体容积是关键，这也是我们计算泵排量的基础。

In the design of pressure control, we use the variable displacement hydraulic pump and electronic overflow control valve and other components of the circuit to control the high voltage, low voltage control circuit composed of electronic discharge valve and so on. But the pressure rise is due to the pressure of the pump's displacement. (we know that the pressure rise, the measurement will be deformed, the volume will increase. Therefore, in the most rapid pulse test, in a number of short time, the volume of the injection of the test piece is the key, which is the basis for the calculation of the displacement of the pump.

二．箱体设计

Two. Box design

我们知道，一个系统是有很多小系统组成的，箱体是由液压系统和热交换系统，控制仪表等组成的一个有机体，在设计中我们首先根据设计要求必须双开门，就是正面和反面都可以开门。在门都安装闭合检测开关，进行测量检测，以满足试验安全性。

We know that a system is composed of many small system. The box body is by the hydraulic system and heat exchange system and control instrument consisting of an organism, in the design we first according to the design requirements must be double door is positive and negative could open the door. The doors are installed with a closed switch, which is measured to meet the safety of the test.

整个箱体外围是个空气循环系统，到测试室的空气，进行充分的热交换，保证箱体的控制温度。当然，箱体间的隔热处理也是十分重要的。

The whole cabinet is a peripheral air circulation system, to the test chamber of the air, the full heat exchange, to ensure the control of the box temperature. Of course, heat insulation between the box is also very important.

箱体尺寸：1500*1000*1000。

Box size: 1500*1000*1000.
