研究了压杆稳定性设计问题,提出了一种新的试算方法,利用Matlab实现了该算法。以圆截面压杆为算例进行了直径设计,结果表明:对于不同的参数设置,均能得到精确解,克服了目前常用的迭代法只能得到近似解的局限性,GUI程序的可视化操作界面极大地方便了工程设计人员的使用。所编程序稍作修改即可推广到其他截面,扩大其应用范围。 Studied the design of the stability of the strut, a new trial calculation method is proposed, and the algorithm is implemented by Matlab. The diameter of circular cross-section bar is taken as an example. The results show that the exact solution can be obtained for different parameter settings, overcoming the limitations of the approximate iterative method that can only be obtained by the iterative method. GUI visualization user interface Greatly facilitates the use of engineering design staff. Program a little modified to be extended to other cross-section, to expand its scope of application.
