摘　　要：本文为中低速内燃机配气机构的最佳设计,提供了统一的优化模型——条件泛函极值问题。并将此模型巧妙地转化成了约束非线性规划问题,可采用多种优化方法求解。不仅为配气凸轮型线设计提供了新的途径,还可广泛用于其它凸轮型线设计,经对实例的计算比较,效果显著。In this paper, we present a unified optimal model, i.e., the minimizing functional with constraints for the optimal design of critical and low velocity internal combustion engine valve mechanism.It is transformed ingeniously into a non-linear programming pro-blem with constraints which can be solved by many optimal methods.This paper not only provides a new method for the valve cam design, but also a method which can be app-lied to other cam designs. Computation of practical examples show that it has remarkable effect.
