摘　　要：利用自行开发的基于单自由度气门—弹簧模型的动力学优化程序 ,对 82 4 0ZJ型柴油机配气凸轮型线及机构进行了研究 ,探讨了不同配气凸轮型线、柴油机转速、气门间隙。By the application of the self-developed dynamic optimization program based on single-freedom valve-spring model, the optimization design of the valve cam profile and valve actuating mechanism is conducted for 8240ZJ diesel engine. The effects of different cam profiles, diesel engine speed, valve gap, valve actuating mechanism rigidity and valve spring rigidity on the performance of the valve actuating mechanism are discussed.
