-
摘要: 针对变截面杆的受压临界载荷确定,本文尝试使用一种快速有效的理论计算方法进行校核,以满足工程应用。该方法使用矩阵传递法进行了理论计算,并使用ANSYS软件和规范KTA3205分别进行了有限元计算和试验验证。结合制造工艺及计算简化处理方法对计算结果进行差异性分析,验证了理论计算方法的合理性和可用性。Abstract: In this paper, the critical buckling loads of these non-uniform section bars are checked by using a quick and effective theoretical calculation method to meet the engineering application. Transfer matrix method used in this method is checked by using the finite element and KTA3205 test method. The differences of these results are analyzed to verify that the theoretical calculation is reasonable and usable by comparing with the manufacturing process and the simplified calculation method.
