24英寸(QH-16型)轻便自行车是一种单横管式自行车,型车重心较低,容易操纵,具有较好的稳定性。车身在一定的高度内可以任意调节,能适应不同身材骑者的要求。QH-16型轻便车功率损耗比一般车辆小,有较好的柔性,行车轻快,乘坐舒适,是一种理想的交通工具。其外形见题头图。为了对这种自行车的强度进行分析,我们采用光测弹性应力方法,对组成车架的前叉、横管、立管及后叉管进行应力测定;还进一步对自行车在上下车、上坡、下坡等各种情况下的动静态应力进行了分析,从
The 24-inch (QH-16) light bicycle is a single cross-tube bicycle with low center of gravity, easy handling and good stability. Body in a certain height can be adjusted, to adapt to the requirements of different body rider. QH-16-type portable power consumption lighter than the average vehicle, with good flexibility, driving fast, comfortable ride, is an ideal means of transport. See the head figure of its appearance. In order to analyze the strength of this kind of bicycle, we use the method of optical measuring elastic stress to measure the stress of the front fork, cross pipe, riser pipe and fork pipe which make up the frame. Furthermore, Downhill and other conditions under static and dynamic stress were analyzed from
