【摘要】 本文以汽车行驶速度分布的实测数据为基础,在充分考虑汽车碰撞初速度对冲击危险程度的影响的前提下,构造了加权函数,采用幂级数与指数函数的复合函数,建立了满足定性分析要求的数学模型,利用外点罚函数方法,实现了汽车前部纵向冲击力学特性的加权最优设计。更多还原

【Abstract】 Based on the qualitative analysis to meet the requirements of occupant crash protection,an optimization design model is created. In the model,the complex function of power series and exponential function is assumed,and a weighting function according to the actual opera-tion data of vehicle velocity and the danger grade for high-speed impact is employed. The optimization design is implemented by using SUMT method.更多还原
