摘要
汽车作为一种高效率的运输工具,运输效率的高低主要取决于其动力性的大小。汽车的动力性是车辆设计时的重要指标,也是人们选择车辆时考虑的重要性能之一。对汽车动力性的评价指标主要有最高车速、加速时间和最大爬坡度,以这3个指标为标准,推导所需计算公式,并以某一具体车型为例,通过MATLAB软件进行仿真,得出该车辆的动力性能参数,供有关人员参考。
Cars, as an efficient means of transport, the level of its transport efficiency mainly depends on the size of its power. Power is an important index in designing a car, so is it an essential consideration for customers. The evaluation indexes of automobile dynamic performance mainly include maximum speed, acceleration time, and maximum climb. This paper takes the above three indicators as the standards, deduces the formula required for the derivation, and, with a specific type as an example, simulates through MATLAB and then obtains the vehicle’s dynamic performance parameters which are used as references for related personnel.
