摘要
在对拖拉机驾驶室骨架进行静、动力有限元计算和静、动态应力测试的基础上,得到了驾驶室应力分布图、骨架测点的动应力统计特性及骨架18阶固有频率和振型图。计算值与实测值吻合,计算模型与方法切实可行,为驾驶室疲劳强度CAD奠定了基础。
On the basis of finite element calculating and stress testingboth dynamically and statically. the stress distribution pattern, dynamic sta-tistic characteristic, nature requencies and vibration models for tractor cabhave been got, with the values of calculation being coincident with those oftest. The calculation model and method have been proved to be feasible.whichlays a foundation for tractor cab fatigue strength CAD.
