查询词典 rough calculation

With CAE analysis, multi-body dynamic model of the loader is established with multi-body dynamics software of finite element NAS-TRAN and MSC Adams/View during design period. Various curve functions are added in dynamic analysis model to simulate the terrain excitation on tires and conduct dynamic calculation and analysis. Stress change vs. time of each part is easily obtained when a loader travels on rough terrain. Compared with test results of the physical prototype, the calculation results are relatively consistent.

The result shows that the mixed boundary condition can greatly reduce the calculation area without affecting accuracy of the solution.It is followed by the higher accuracy of Dirichlet boundary condition which makes the boundary error greater when measured points is near the boundary, so we must take a sufficiently large border region.The homogeneous boundary condition has relatively large error, but the use of non-triangle poles devices makes apparent resistivity calculation error become small, because of elimination of the effect on potential difference for the infinite boundary. In inversion, in order to save computing time, homogeneous boundary conditions are often used to perform finite element forward calculation.

结果表明，混合边界条件精度最高，可大大缩小求解区域而不影响计算精度，其次是Dirichlet边界条件精度较高，但测点越靠边界误差会越大，必须取足够大的边界区域，齐次边界条件的误差比较大，但如果采用非二极装置，通过电位差计算得到的视电阻率，由于无穷远边界对电位差的影响基本消除，视电阻率计算误差与混合边界条件下的接近，在反演中，为了节省计算时间，经常使用齐次边界条件进行有限元正演。
