旋转疲劳机Mk3-工程实验室训练系统

模型HV-EXP4860
特点自备工作台完全防护故障转数读数电机在试样失效时停止有颈的试样，钢，铝合金和黄铜理想的疲劳介绍交变弯曲疲劳可选额外的三年保修实验范围使用维勒旋转疲劳仪对疲劳进行介绍性研究，包括由各种应力水平和材料引起的故障时间附件，HSM19X提供悬臂式金属或塑料带的弯曲疲劳，模式从交变到波动应力。一个简单的悬臂试件以大约5700或1425转/分的速度旋转，引起弯曲应力的正弦变化。在更快的速度下，每小时会发生三分之一的应力逆转，所以故障应该在一天内发生。使用带应力提升器的试样可以加速试样的失效。加载系统取消其自重，使任何期望值的弯曲应力应用，十个低碳钢试样提供。轴向性已得到保证，并已采取措施减少振动的影响。当故障发生时，一个微开关停止电机，故障周期被记录在一个5位数的转数计数器上。所有旋转部件都被屏蔽，并提供一个安全防护来抑制破碎的试样。该设备安装在一个沉重的钢底座上，并被设计成悬垂在放置它的工作台或底座上。 Ideally a heavy pedestal (eg concrete), isolated from the floor by rubber matting, should be used to minimise shock loads. An additional accessory for alternating bending fatigue and additional specimens are available. This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results..
