基于非线性悬置的拖拉机ROPS性能分析方法
|
摘要
使用有限元方法对拖拉机翻滚防护装置(ROPS)进行强度分析时,对驾驶室悬置性能的模拟是整个驾驶室ROPS分析的关键。使用一维非线性六自由度梁单元模拟整个悬置的性能,并结合有限元分析中的重启动技术完成了某拖拉机驾驶室的ROPS分析。通过对比试验结果,后推和侧推工况与试验的峰值力相差16.3%和13.1%,各工况仿真和试验的变形结果一致,表明分析方法的可靠性,该方法能够有效提高拖拉机驾驶室OECD试验要求的通过率。
The simulation of cab suspension is the key to entire ROPS analysis when finite element method is used to calculate the ROPS strength.The suspension is modeled with nolinear beam elements which has six degrees of freedom,and combining the restarting technology of finite element method,a cab ROPS analysis is completed.According to the simulation and the test results,the difference between the peak force of simulation and test is 16.3% and 13.1% respectively during rear pushing and side pushing load step,And the deformation results of the cab simulation and test have a good agreement,that shows the ROPS is able to meet the cab requirements.The analysis method can effectively improve the pass rate of tractor cab OECD test.
