Abstract

An elastic element widely used in machine engineering is spring. It is used predominantly for the amortization of impulses and shocks (for smoothing and leveling of the load in the contact zone of related details of design). The paper reviews general dependences between the deformations and transitions of springs in cylindrical coordinates. Considered task is modeled in axysimmetrical form. In solution of general equations semi-inverse method of Saint Venant is applied. Stressed-deformed state of a cylindrical spring has been studied during the action of different loads (equally distributed intensity q or fixed load p). To specify stressed-deformed state of a spring, a principle of power dependence and superposition method is used. At first, the components of stress and transitions of each power separately are defined, and then corresponding power factors (stress components from each power separately) are summarized using superposition method. The agents for designing spring construction considering existing loads have been obtained.

圆柱弹簧的应力变形状态
弹簧是机械工程中广泛使用的一种弹性元件。它主要用于脉冲和冲击的平摊(用于相关设计细节接触区负载的平滑和平衡)。本文综述了圆柱坐标系下弹簧变形与跃迁之间的一般关系。所考虑的任务以不对称的形式建模。在一般方程的求解中,应用Saint Venant半逆法。研究了圆柱弹簧在不同载荷(均布强度q和固定载荷p)作用下的应力变形状态。为了确定弹簧的应力变形状态,采用了功率相关原理和叠加法。首先分别定义各功率的应力分量和过渡分量,然后用叠加法总结相应的功率因子(各功率的应力分量)。得到了考虑既有荷载的弹簧结构设计的依据。
