摘　　要：将传统光杠杆中平面镜和标尺之间的平面光路立体化,设计了多次反射、旋转上升式光路.以Solidworks软件为设计手段,利用3D打印技术,制作了激光器为光源的小型光杠杆装置.利用传统光杠杆和小型光杠杆对钢丝的杨氏模量进行了对比测量研究.实验结果表明,设计制作的小型光杠杆装置空间尺寸小,操作简单,仪器制作方便,测量结果准确.对于开拓学生思维,提高学生的创新能力有一定的借鉴意义.Based on the deficiency of the traditional optical lever device,the plane light path between the plane mirror and ruler in the traditional optical lever was three-dimensional,and a multi-reflection and rotating rising light path was designed.Using Solidworks software as a design means,a laser-based micro-light lever device was produced using 3D printing technology.Taking the Young modulus measurement of wire as an example,a comparative experiment was carried out using traditional optical lever and micro-optical lever.The experimental results shown that the micro-optical lever designed and produced was small in size,simple to operate,convenient to make instruments and was accurate to measure.It was reference to develop students'thinking and improve students'innovation ability.
