一、概述 汽车在公路上行驶,除受到振动负荷以外还受到冲击载荷。冲击载荷产生的原因是多方面的,如在不平的道路上簸波;高速行驶时遇到障碍物和急刹车等都能对汽车产生比较大的冲击力,这样,汽车电器系统亦相应的受到冲击力。为此在这次 First, an overview of the car driving on the road, in addition to the vibration load but also by the impact load. Impact load is caused by many factors, such as rough roads on the jolts; obstacles encountered at high speeds and braking can have a greater impact on the car, so that the car electrical system is also subject to impact. To this end at this time
