1965年7月在哈尔滨召开了房屋结构和动力机械基础振动学术会議,今年2月,学报发表了会議专题讨论综合发言“动力机械基础和防微振若干问题”,作者根据浅薄的体会对9个有关问题提出补充意见,幸讀者指正。一、有关锻锤及空压机基础振动的专题(一)地基弹性竖向刚度C_z值的确定C-z值是表示地基刚度的一个常数,稚度是公斤/立方厘米。因此它是一个描述空间力分布的系数,不同于弹性模量E_z(公斤/平方厘米)的是多了一个深度关系,也就是考虑到压缩面的有效深度。作者根据经验数字提出一个简单估算公式:
In July 1965, an academic conference on building structure and foundation vibration of power machinery was held in Harbin. In February of this year, the journal issued a panel discussion on the topic of “Power Machinery Foundation and Some Problems of Preventing Micro-vibration”, which was based on a shallow 9-person experience. Supplementary comments on the relevant issues, fortunate readers correct me. I. Special Topics on Basic Vibration of Forging Hammer and Air Compressor (1) Determination of C_z Value of Foundation Vertical Elastic Stiffness The C-z value is a constant representing the foundation stiffness, and the childishness is kg/cm3. Therefore, it is a coefficient that describes the spatial force distribution, which is different from the elastic modulus E_z (kg/cm2) by a depth relationship, that is, considering the effective depth of the compression surface. The author proposes a simple estimation formula based on the empirical figures:
