【求助】ADAMS/CAR仿真問題 已有3人參與

我在car里面建立了一個(gè)4WS整車模型,進(jìn)行角階躍實(shí)驗(yàn),只能進(jìn)行40km/h以上的仿真,此速度以下的仿真失敗,給的階躍信號都相同。失敗提示如下: ---- ERROR ---- Attempt = 1. No convergence after 25 iterations. Best iteration = 22. Trying next attempt with a different set of statics parameters... For the last attempted iteration the equation with the largest error was VARIABLE ddddddd_step.testrig.vas_brake_demand.variable Error = 2.64434E+07 The variable receiving the largest increment was FIELD ddddddd_step.TR_Front_Suspension.bkl_top_mount.field Delta = 7.55915E+09 ---- ERROR ---- Static equilibrium analysis has not been successful. Restoring the input initial conditions... ---- ERROR ---- Sim/stat cannot be achieved ...Stopping in ID = 1020 Terminating Adams/Car usersubs... Adams/Solver execution terminated by subprogram ERRMES CPU time used = 2.3281 seconds Simulation is complete. 這是怎么回事?同一個(gè)模型為什么低速仿真不成功? |

我也有同樣的問題啊,已經(jīng)困擾我半個(gè)多月了,一直不知道是哪里的問題。靜態(tài)仿真總是失敗,針對失敗原因進(jìn)行修改后又會(huì)出現(xiàn)新的錯(cuò)誤提示,到底是模型問題還是軸套剛度問題啊。。有沒有大神可以指點(diǎn)一下啊 Attempt = 1. No convergence after 25 iterations. Best iteration = 10. Trying next attempt with a different set of statics parameters... For the last attempted iteration the equation with the largest error was PART f_static.suspension_rear_single_0201.gel_hub Error = 4.18679E+08 The variable receiving the largest increment was FIELD f_static.leaf_spring_front.bgr_bushing1.field Delta = 6.14416E+08 |
