摘要
在脉冲力校准中,锤体质量块的力学性能会对校准结果产生较大影响。本文采用有限元手段,对锤体质量块的结构设计方案和受力方式进行分析,得出锤体质量块动态特性的影响因素,总结脉冲力校准中锤体质量块设计和使用时应遵循的规律,为动态冲击计量标准装置的研建提供借鉴。
The mechanical properties of hammer mass have a great impact on the result of impulse force calibration.In this paper,the fi-nite element method is used to analyze the structural design and load mode of the hammer mass,and the influence of the above factors on the dy-namic characteristics of hammer mass is obtained.The rules that should be followed in hammer mass design and use in impulse force calibration are summarized.
