疲劳测试是机器和车辆制造中质量保证的重要元素。为了进一步增强其在该领域的教学，HS ULM（乌尔姆应用科学大学，德国）在研究项目的一部分中开发了一个疲劳测试架，用于悬架叉子，并在亚博老虎机网登录Zwickin the form of equipment and expertise.
该项目涉及研究对下坡旅行时产生的环状载荷的山地自行车悬架叉的影响。为了获得现实的数据，使用摄像机来记录下坡骑自行车上的阻尼旅行，并通过内部软件进行数据导入数据。
Ulm University of Applied Sciences builds special test stand
The test stand was also designed by the university and comprises a four-column load frame. Suspension forks are subjected to cyclic loads via a servo-hydraulic testing actuator attached to the lower mounting-plate. System control is by ControlCube - 'the world's smallest controller' - with Cubus testing software. A particular feature of this combination is ease of operation, allowing students to quickly become familiar with fatigue testing and carry out tests unsupervised after only a short time. As an added bonus, the system's 4kHz control frequency, 19-bit-resolution data-logging and capacity for expansion to 32 control channels enable it to be used for more complex applications whenever required.
来自现场测试的数据是通过CUBUS软件导入的，用于执行逼真的仿真测试。“使用Zwick迭代软件，我们可以导入并模拟任何给定的路线概况，并在实际条件下生成有关磨损和负荷的发现，” Dipl说。ing。HS Ulm的测试实验室的Daniel Stiehle。ControlCube还用于从应用于叉式安装的应变计中导入数据，提供有关叉子上本地负载的详细信息。
