摘要
圆柱弹簧的伸缩呈现出不均匀性,其速度波和压力波是外加载荷的动态响应。通过对弹簧拉伸过程中的相对变形度的分析,找出影响弹簧均缩性的因素,导出了相对变形度与拉伸速度之间的关系式。结合舞台大幕均缩机构的工作特点,对其进行进一步的分析计算,并将结果应用于工程实践,满足了演艺设备的需要。
Asymmetrical deforming was observed for cylindrical spring. The speed and stress waves were dynamic response under loading. Analysis about the ratio of relative deformation during spring elongation has bccn carried out. So that, the influence factors of proportional constriction for spring can be found and what＇s more a function of relative deformation and loading speed was obtained as well. A further study was done for this function considering the characteristic of proportional constriction structure for stage curtain opener. The achievement of this study has been used in practical working to meet the request of performing facilities.
