【摘要】：以某離合器波形片為研究對象,利用Dynaform有限元軟件對波形片的成形回彈進(jìn)行數(shù)值模擬,分析了波形片回彈前與回彈后的應(yīng)力分布,研究了模具間隙及板料厚度對波形片回彈后成形高度的影響。模擬分析表明,波形片彎曲成形的圓角處變形比較劇烈,其應(yīng)力值較其他區(qū)域值更大,且回彈后應(yīng)力值的減小使得板料發(fā)生回彈,而回彈使得波形片成形高度降低,從而影響離合器從動盤總成的彈性;波形片的成形高度隨著模具間隙的增大而減小,而隨著板料厚度的增加而增大。試驗(yàn)結(jié)果表明,當(dāng)板料厚度分別為0.6和0.8mm時,試驗(yàn)值與模擬值的誤差變化范圍分別為5.44%~7.54%和4.52%~5.93%,模擬結(jié)果與試驗(yàn)結(jié)果取得較好的吻合性。
[Abstract]:Taking a clutch corrugated plate as an object of study, the forming springback of a wave-form sheet was simulated by using Dynaform finite element software, and the stress distribution before and after springback of the wave-form sheet was analyzed. The effects of die clearance and sheet metal thickness on the springback height of the corrugated sheet were studied. The simulation analysis shows that the deformation at the corner of the wavy sheet is more severe, and the stress value is larger than that in other regions, and the reduction of the springback stress value makes the sheet material rebound, and the springback results in the reduction of the forming height of the corrugated sheet. Thus, the elasticity of the clutch follower assembly is affected, and the forming height of the waveform plate decreases with the increase of the die clearance, and increases with the increase of the thickness of the sheet metal. The results show that when the thickness of sheet metal is 0. 6 and 0.8mm, the error range between the test value and the simulated value is 5.447.54% and 4.52% respectively. The simulation results are in good agreement with the test results.
