液压减震器综合反力特性测控系统设计

摘要液压减震器的工作原理是当它加压时，连接轮子的下压力管上升，将活塞推入连接车厢的另一根轴筒；活塞上有标准小孔，孔上安装油压嘴，润滑油穿过油压嘴而起到阻尼减震器上升的作用。反之，轮子在悬挂弹簧压力下便恢复原来的位置。51172

在设计过程中主要通过查资料以及做实验等方法进行了综合反力特性的研究。本文主要包括了液压减震器的结构分析、硬件组成、软件设计和测试结果分析等部分。本测控系统综合了位移/力传感器、数据采集系统、电液系统以及测试软件与一体。在整个设计过程中，主要是进行了数据采集系统的设计以及分析了数据采集系统中各模块是如何实现数据转换和采集的，对其中的FX2N-4AD和FX2N-2DA进行了内部软件初步分析。同时也设计了比较简易的减震器液压系统原理图。在次同时进行了减震器软件设计，并且设计出了可以实现对减震器综合反力特性进行检测的C++ builder界面。使用本次的设计测试系统，可以有效地快捷的测试出减震器是否合格，极大地提高了减震器的安全性。

Abstract

The working principle of hydraulic shock absorber: Connect the wheels under pressure pipe rose when it is pressurized. It will push the piston into the other shaft tube which connects compartments. The piston has a standard hole. There is a Nozzle in the hole, lubricating oil through the oil nozzle can stop the damper rose. On the contrary, the wheel will restore the original position under the pressure of suspension spring.

During the design process, we mainly by searching the information and doing experiment to study on the comprehensive force. This paper mainly includes the analysis of hydraulic shock absorber structure, hardware composition, software design and the analysis of test results and so on. The measurement and control system combines the displacement / force sensor, data acquisition system, hydraulic system and test software and integration. During the whole process design, mainly carry on the design of data acquisition system and analysis the module of data acquisition system is how to realize the data conversion and acquisition, on which FX2N-4AD and FX2N-2DA were internal the software preliminary analysis. At the same time, I also design the simple principle of hydraulic system of shock absorber. At the time of the shock absorber design of software, I design the C++ builder interface to achieve reverse characteristics of shock absorber. Using the testing system effectively and fast test of shock absorber is qualified; the safety of shock absorber is greatly improved.

Keywords: hydraulic shock absorber; synthesis reaction; test system
