主横梁 meaning in Chinese

main beam

According to eigenvalue equation ( general formula ) of the energy method of the plane steel frame structure stability , and considering the restriction of the end of the column of the main steel frame and function of deflection curve gained from the differential balance equation general resolution , we get the equation for calculating the length coefficient of the main frame structure stability of the steel arch gate and the resolutions are also given
根据平面刚架稳定性能量法特征值方程(通式) ，考虑弧形钢闸门主框架柱的柱端约束的特殊情况，求出挠曲线函数(试解函数)通解，得到弧形钢闸门主框架柱稳定性计算长度系数方程。其中弧门主框架主横梁式形框架的临界荷载比较现行规范推荐的有限元法简单方便、结果精确及物理概念明确等优点。
In order to get the vibration information of computerized embroidery machine , failure - energy theory and perpendicular wavelet package method are applied to the modal ga920 , the character energy vector is gotten and a new method of failure identification is found
摘要为得到电脑刺绣机在不同振动状态的准确信息，应用“故障能量”的理论和正交小波包变换的方法对ga920型电脑刺绣机主横梁的振动信号进行分析，得到了不同振动状态的能量向量，为电脑刺绣机的故障诊断提供了一种新的解决方法。
