货架支架采用工字形截面。 The axial rotation is restricted on both ends while warping is enabled. The structure is loaded by two transverse forces in the middle. The verification example is based on the example introduced by Gensichen and Lumpe.
该验算示例是基于验算示例 0122 编写的. A single-mass system without damping is subjected to an axial loading force. An ideal elastic-plastic material with characteristics is assumed. Determine the time course of the end-point deflection, velocity, and acceleration.
定义一个简单振动器,由质量 m(只考虑 x 方向)和刚度为 k 的弹簧组成。 The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
该类型的悬臂梁截面为矩形,在端部有一个质量块。 Furthermore, it is loaded by an axial force. Calculate the natural frequency of the structure. Neglect the self‑weight of the cantilever and consider the influence of the axial force for the stiffness modification.
