做柔性体仿真,从ANSYS导入模态中性文件时有这个报错. Negative pivot encountered. This is likely caused by insufficient displacement constraints or improper master dof selection to avoid rigid body motion of the superelement region currently selected. 还有一个 superelement file
源:机器人局部避障的动态窗口法(dynamic window approach) 首先在V_m∩V_d的范围内采样速度: allowable_v = generateWindow(robotV, robotModel) allowable_w = generateWindow(robotW, robotModel) 然后根据能否及时刹车剔除不安全的速度: for each v in allowable_v for each w in allowable_w dist = find_dist(v,
张建伟等.2012.12 人民邮电 一天一本书,这种感觉 真是爽啊. 但我觉得什么也没学到. 话说回来,此authors 确实书写得比较一般,实例不如百度文档上的WORD实例,理论不如我看的那本CFD ,然后造成我一边看这本一边想重读CFD. 这本侧重机械工程,因我觉得没什么用. GPU高性能编程CUDA实战 CUDA by example: an introduction to general-purpose GPU programming 索书号:TP391.41 ZS170 Windows
