集总质量 meaning in Chinese
lumped mass
Examples
- Lumped mass matrix
集总质量矩阵 - Using the approximation form of lumped mass matrix instead of the mass matrix in finite element discretization in space , backward differencing scheme in time , an implicit computational scheme is yielded , it proved the convergence estimate for this implicit scheme
对有限元离散中引起较大误差的质量矩阵，采用了近似形式的集总质量矩阵来代替，时间项采用向后差分，得到了一个隐式的计算格式，证明了计算格式的收敛性及其收敛速度估计。 - The compute model of shafts of the machines is built by adopting concentrated mass method . taking into account the different support conditions of the shafts that workshop is considered as rigidity or elasticity ; the natural characteristic and unbalanced response of the shafts are computed by integrating with high stable riccati transfer matrix method
采用集总质量法对机组轴系建立了计算模型，并结合稳定性良好的riccati传递矩阵法，分别考虑机组轴系的支撑基础(厂房)为刚性、弹性两种情况，计算了机组轴系的自振特性、轴系的不平衡响应。
