本文讨论受到多频率约束的铁木森柯梁和尤拉梁的最小重量设计问题。
The present paper discusses the minimum weight design problem for Timoshenko and Euler beams subjected to multifrequency constraints.
柯特·韦尔奇本身是一名电脑软件工程师。两年前加入这个组织。他说：“我立刻就被这种工艺的艺术性以及用铁能表现出来的各种神奇迷住了。”
"I immediately became fascinated with the artistic nature of the craft and all sorts of magic of working with metal," says Welch, a computer software engineer who joined the group two years ago.
由于这类轴具有较小的长径比，因此，在分析它的振动时，采用铁木辛柯梁理论比欧拉梁理论更为合适。
Because of the smaller ratio of slenderness, the theory of Timoshenko beam is more suitable than Bernoulli-Euler beam's for analysis of the dynamic behavior of stepped shaft.
