摘要
通过对GN-12手扶拖拉机新、旧机架的振动测试和频谱分析,确定了机架和S195柴油机所组成系统的固有频率、刚度和阻尼等参数,结果证明新机架具有较好的力学性能和工艺性能。
Through vibration testing and frequency spectrum analysisingfor new and old frames.of model GN-12 walking tractor, natural frequency, rigi-dity and damping for system of frame and model S195 diesel engine were deter-mined, the results have proved new frame has better mechanics and process pro-perty than old.
