(1)平曲线半径是根据什麽公式计算的(1203)? 当汽车在平曲线上行驶的时候,作用在车体上共有三个主要的力:即重力:(车体重量)、离心力及路面的侧向阻力。由于离心力的作用,汽车有向曲线外侧滑动或倾复的可能。计算平曲线半径的理论公式,一般是建立在抵抗侧向滑动的稳定条件上,必要时也需要验算抵抗倾复的稳定性。关于它们的力学关系和公式的写出说明如下:
(1) According to what formula is the flat curve radius (1203)? When driving on a flat curve, there are three main forces acting on the vehicle body: gravity: (body weight), centrifugal force and the road surface Lateral resistance. Due to the centrifugal force, the car has the possibility of sliding or tilting to the outside of the curve. The theoretical formula for calculating the radius of a flat curve is generally based on the stability of lateral sliding resistance and, if necessary, of checking the stability of the resistance against tilting. The mechanics and formulas for their writing are described below:
