汽车是最常用的城乡交通工员。克服汽车的振动,使车辆跑得又快又平稳,是一个非常重要的课题。公路路面不平是汽车振动的主要原因,因此首先要弄清路面不平的性质。实验表明,路面不平是一个随机过程,它在偶然性中表现出确定的规律性。掌握路面不平的规律性,是正确认识和改造汽车和路面相互作用的基础。 Cars are the most common urban and rural traffickers. Overcoming the vibration of the car and making the car run fast and smoothly is a very important issue. Road surface unevenness is the main reason for car vibration, so we must first understand the nature of the uneven road. Experiments show that uneven road surface is a random process, which shows certain regularity in contingency. Grasping the regularity of uneven roads is the basis for correctly understanding and transforming the interaction between vehicles and pavements.
