根据摩托车钳体零件的结构特点,在用Auto CAD软件设计出模具的二维平面图的基础上,以Pro/E所建立的三维实体模型为平台,用3D-MAX动画软件对模具进行了运动仿真,同时用铸造模拟软件JSCast对钳体成形过程中的流场和温度场进行了模拟.仿真和模拟与实际情况相符,在零件的圆转角厚大部位处出现缩孔.在对模拟结果进行比较后,通过在铸件厚大部位增设型芯的办法,实现了铸件壁厚的均匀分布,铸件的凝固过程得到了改善,消除了厚大部位的热节,提高了铸件的品质.
根據摩託車鉗體零件的結構特點,在用Auto CAD軟件設計齣模具的二維平麵圖的基礎上,以Pro/E所建立的三維實體模型為平檯,用3D-MAX動畫軟件對模具進行瞭運動倣真,同時用鑄造模擬軟件JSCast對鉗體成形過程中的流場和溫度場進行瞭模擬.倣真和模擬與實際情況相符,在零件的圓轉角厚大部位處齣現縮孔.在對模擬結果進行比較後,通過在鑄件厚大部位增設型芯的辦法,實現瞭鑄件壁厚的均勻分佈,鑄件的凝固過程得到瞭改善,消除瞭厚大部位的熱節,提高瞭鑄件的品質.

Aiming at structural features of motorcycle brake clamp body, based on 2D model designed by the Auto CAD, visualization of the model was developed with the help of 3D-MAX software on established 3D model platform by Pro/E software, and flow field and temperature field in the parts during filling process were simulated by the JSCast software. The simulated results are well in agreement with the experimental ones, so potential defects and their position in the parts were predicted by the model, and processing design was examined by the JSCast software with the completion of optimized design. Solidification process was obviously improved as a result of uniform distribution of temperature field in wall thickness by setting core at thick position of the parts, eliminating the hot spot in thick position and improving the quality of the parts.
