摘　　要：对CA6140型车床进行了空运转试验和噪声试验,获取机床的空运转状况下的振动和噪声信息,分析研究了机床的动态性能,尤其是机床的抗振性能做出了评价,并用振动诊断和噪声诊断方法,找出了该车床主轴箱传动系统中的薄弱环节,并提出相应的改进措施,以期进一步提高其抗振性。It is set up that the free load examination and the noise examination for the lathe type CA6140.The vibration information and noise information under the free running condition can be obtained.As a result of signal treatment,the dynamic performance can be analyzed and the antivibration capability of lathe can be estimated.In the meanwhile,the weak parts of transmission system of the lathe headstock can be exposed by the vibration diagnosis and noise diagnosis.The other objective of paper is present the reasonable modification method in order to improve more the antivibration capability.

关 键 词：机床的抗振性 薄弱环节 空运转试验 噪声试验
