| 考虑质量时处于转动参照系中的弹簧并非均匀伸长使得其中应力逐点变化。从理论上推导了转动参照系平面与水平面成任意角时有质空载弹簧匀速转动情况下弹簧的应力分布公式和长度公式,根据公式编程写程序分别绘制出了3种角速度下、3种倾角下弹簧应力分布图和3种倾角下弹簧长度图。在工程设计中利用该公式既可方便、快捷地选择弹簧,又可准确地确定弹簧的应力分布或预测弹簧的长度,保护弹簧。 |
| 英文摘要: |
| When considering the mass of spring in rotating system the spring will not uniformly stretches,which makes the stress distribution point-to-point changes.In this article the author theoretically deduces the formulas for stress distribution and spring length without load in uniform rotating system when the angle which is made by the plane of rotating system and horizontal plane is arbitrary.According to the formulas the author writes out the programs and respectively maps out both the stress distribution under the circumstances of three angular velocity and three inclined angels and spring length in the conditions of three inclined angels.In engineering design one can both easily and quickly selects spring and accurately determine the stress distribution or forecast the length of the spring so as to protect springs. |
