摘要
该文针对广东理工学院大学物理实验中心使用的DH-GBL-Ⅱ型焦利氏秤弹簧劲度系数实验仪,在实验中存在的两点不足进行改进设计,并给出具体的设计方案。为验证设计方案的可行性,利用SolidWorks 2018软件对各个改进后的二维零件图进行三维零件建模设计,最后将所有零部件进行装配建模,并在软件中仿真运行,验证其可行性。结果表明,改进设计后的实验仪不仅能够完全满足弹簧劲度系数测量要求,还能大幅度降低仪器零部件的丢失率、腐蚀率,提升了仪器的使用寿命,节约实验成本;同时避免了弹簧在长期使用过程中因形变和氧化导致的弹性力下降而不能准确测量的弊端,使弹簧劲度系数实验仪的测量精度和工作效率得到了大幅度提升。
This paper presents an improved design for the DH-GBL-II Jiaoli scale spring stiffness coefficient experimental instrument used in the University Physics Experiment Center of Guangdong University of Technology,addressing two shortcomings in the experiment,a specific design scheme is provided.To verify the feasibility of the design scheme,3D part modeling was designed for each improved 2D part drawing using SolidWorks 2018 software.Finally,all components were assembled and modeled,and simulation runs were conducted in the software to verify their feasibility.The results show that the improved experimental instrument not only fully meets the requirements for measuring spring stiffness coefficients but also significantly reduces the loss and corrosion rates of instrument components,extending the instrument’s service life and saving experimental costs.At the same time,it avoids the drawbacks of inaccurate measurement due to the decrease in elastic force caused by deformation and oxidation of the spring during long-term use,greatly improving the measurement accuracy and work efficiency of the spring stiffness coefficient experimental instrument.
