支承弹簧 meaning in Chinese

bearing spring
support spring

Firstly , finite element model of lathe spindle using finite element technique is established , and supporting bearings are treated as springs , unknown physical parameters and partial vibration displacement make up of new solving vector through using method of combination of academic modeling and experiment , mathematic model of solving stiffness of beating of lathe spindle is established using inverse analysis method of response problem finally
建立了机床主轴的有限元模型，将支承轴承简化为支承弹簧，通过理论建模与实验相结合的办法，将待识别的物理参数和部分振动位移组成新的求解向量，利用响应问题的逆分析方法建立了求解主轴轴承刚度的数学模型。
