输弹簧设计

对于弹仓式供弹机构而言,输弹簧的装配高度决定了弹仓总体高度的大小。针对弹匣中的输弹簧,提出在满足供弹及时性的基础上,把设计重点放在减小输弹簧装配高度上的思想。在对实际模型合理简化的基础上,采用理论推导的方式,找出棱柱螺旋弹簧的最小装配高度设计方法,并将其推广至任意非圆形轮廓螺旋弹簧。通过实例说明新方法的具体应用。这对减小弹匣的总体高度及武器减重方面有积极作用,并对新型弹簧的设计有一定的指导意义。

Educational Press for Remote Experimentation Applied in the Spring to Study Hooke＇s Law

The aim of this study is to report the use of RE （remote experimentation） in an educational press. The authors developed this remote experiment with the objective to study the Hooke＇s law through the analysis of the coil spring. The remote experiment is available in a website, where the students can manipulate and observe the educational press and confirm Hooke＇s statements with the output information. In addition, the students will have the opportunity to read in the website about the educational press, the physical law, and the use of the press in industrial processes. This remote experimentation exerts a force in the mechanical spring creating a deformation. In the defined point, the microcomputer will collect the data from the sensors, and it will save this data in the database. After the process execution, a graph with the data will be plotted in the website. The tests confirm that the educational press has informational potential because it returned values consistent with Hooke＇s law and the experiment presented repetition in all tests realized.
