Abstract

The expected preloading effect of a hydraulic press frame parts (upper/lower semi-circular beams and columns) with pre-stressed by means of Winding Steel Wires which is directly related to the reliability and normal safe operation of the hydraulic press. The deformation of the Hydraulic Press Column (HPC) is an important indicator of the optimal preloading effect of the hydraulic press. A novelty of this project is to break through a bottleneck technology, the continuous cumulative deformation of a Hydraulic Press Column under seven time-varying steps is critical issues especially in theoretically calculated for a 20 MN double-frame hydraulic press with pre-stressed using WAW. A solid model with a pre-stressed frame is pre-designed by 3D software, and two simulation methods, equivalent pressure loading and equivalent temperature loading, are used to simulate and analyze the continuous cumulative deformation of the HPC under each step in Ansys Workbench software. By comparing the deformation and error analysis in the three cases above, the feasibility of the two simulation methods is verified, which leads to the advantages and disadvantages of each method in order to guide the subsequent design.

20MN重型液压机双框架预应力钢丝缠绕分析的数值计算

缠绕钢丝预紧液压机机架部件(上下半圆梁、柱)预紧效果的预期好坏，直接关系到液压机的可靠性和正常安全运行。液压机柱的变形是衡量液压机最佳预压效果的重要指标。本课题的新颖之处在于突破了液压机柱在7个时变阶下的连续累积变形问题，特别是对20mn双机架预应力液压机进行了WAW理论计算。通过三维软件预先设计预应力框架的实体模型，采用等效压力加载和等效温度加载两种仿真方法，在Ansys Workbench软件中对HPC在各步下的连续累积变形进行仿真分析。通过对比上述三种情况下的变形和误差分析，验证了两种仿真方法的可行性，从而得出每种方法的优缺点，从而指导后续的设计。
