改进CG125发动机气道和燃烧室形状,在保证动力性提高的同时,也会导致活塞连杆曲轴温度和强度负荷增加。采用有限元模拟分析,计算出活塞连杆曲轴改进前后的应力和活塞温度变化,通过改进活塞形状,保证了改进后发动机活塞热负荷状况良好,同时提高了活塞连杆曲轴强度。
Improved CG125 engine airway and combustion chamber shape, while ensuring the dynamic increase, but also lead to the piston rod connecting rod crankshaft temperature and strength load increases. The finite element simulation analysis is used to calculate the stress and piston temperature before and after the piston rod crankshaft is improved. By improving the piston shape, the engine piston thermal load is improved and the crankshaft strength of the piston rod is improved.
