接触问题是普遍存在而又比较复杂的问题。利用光电扫描的云纹实验准确地测量出了缠绕压机半圆梁圆周的接触荷载,根据实验结果提出了半圆梁圆周荷载的一般分布规律及其数学表达式,为云纹法成功地解决接触问题提供了范例。利用实测荷载作边界条件,对缠绕压机机架进行了有限元计算,为压机的强度和刚度设计计算提供了可靠的依据。
Contact problems are ubiquitous and complex issues. The contact load on the circumference of semicircular beam of the winding press was measured accurately by the moirometry experiment of photoelectric scanning. Based on the experimental results, the general distribution rule and mathematical expression of the circular load on the semicircular beam were proposed, which could be used to successfully solve the contact problem Provided an example. Using the measured load as the boundary condition, the finite element calculation of the winding press racks is provided, which provides a reliable basis for the design and calculation of the strength and rigidity of the press.
