摘要随着科技的发展，21世纪我国的工业水平较以前有了很大的进步，而伴随而来的就是各行各业技术的不断创新与发展，减震器这一行业也不例外；目前，减震器遍布在我国的大多数工业产品中，而随着工业产品的更新升级，对于减震器的性能要求也在不断提。84909
目前我国对于减震器性能的测定主要有减震器示功特性、减震器缓冲弹簧性能测试以及减震器耐久性测试等。其中对于减震器耐久性的测试，目前已知的有转鼓式试验台，其可对减震器进行循环冲击，在一定的周期内对减震器的冲击次数达到60-100万次，其是目前最常用的减震器耐久性测试试验台。
本篇文章描述了一种新式减震器耐久性测试试验台，其为具有连续自动抓取释放功能的落锤式减震器，其设计方案来源于落锤式材料试验机，通过落锤对减震器的连续性冲击，当达到一定的次冲击次数，从而验证减震器的性能是否合格。
首先，对该实验台的传动方案进行设计，确定其通过变频减速电机、滚轮以及滑轮进行传动，其次根据设计任务的速度要求以及传动方案计算所需减速电机的转速功率以及传动比；接下来开始分析设计该实验台控制系统的原理以及流程，进行传感器开关的布置，然后根据所设计的控制系统流程进行控制系统的硬件设计，其包含：变频器与计数器的选型、I/O表设计以及PLC选型、电气原理图绘制、端子排的设计、开关电源供电方案设计以及控制柜的设计；待以上任务结束后，开始使用GX developer进行PLC梯形图的编写，最后使用GX simulator进行PLC梯形图的仿真调试，通过其所呈现的时序图观察梯形图中的逻辑关系是都正确。
本试验台相对于其他减震器耐久性试验台的优势就是效率高，使得该试验台能够充分应用到实践中，成为减震器耐久性测试的十分可靠的方法。

Abstract With the development of science and technology, the 21st century China's industrial level than before significant progress, and accompanied by is the innovation and development of technology of all trades and professions, shock absorber, the industry is no exception; at present, the shock absorber throughout most of China's industrial products, and with the escalation of the industrial product updates, performance requirements for shock absorber also has been improving。
At present, the performance of the shock absorber is mainly determined by the performance characteristics of the shock absorber, shock absorber buffer spring performance test and shock absorber durability test, etc。。 Which for shock absorber durability test。 It is now known that the transfer drum test bench, the cyclical impact of the shock absorber, within a certain period on the shock absorber shock times of reach 60-100 million, is currently the most commonly used shock absorber endurance test test bench。
This article describes a new shock absorber durability test bench, as with continuous automatic capture release function drop type shock absorber, the design scheme from falling weight deflectometer (material testing machine, by drop hammer on the shock absorber of continuous shock, when reaching a certain amount of impact times to verify shock absorber performance is whether qualified。
First of all, the design of the experimental transmission scheme, determine the through frequency conversion speed motor, wheel and pulley transmission, and then calculated according to the requirements of speed and the transmission scheme design tasks required for motor speed reducer and the power transmission ratio; then analysis the design principle of control system and flow sensor switch arrangement, and then the hardware design, control system according to the procedure of the designed control system includes: inverter and counter selection, the design of I/O and PLC selection, electrical principle drawing, terminal design, switching power supply design and control cabinet design; to be more than the end of the task, start writing using GX developer PLC ladder diagram, debugging simulation and finally use the GX simulator PLC ladder diagram, the It is correct to observe the logic relation of ladder diagram in the time sequence diagram。 具有连续自动抓取释放功能的落锤式减震器冲击试验台控制系统设计:http://www.youerw.com/zidonghua/lunwen_101207.html
