~~~~~~~~~~~~~~~~~~~~~~Regular Model~~~~~~~~~~~~~~~
In this model, the radio range is a circle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ReceivedSignalStrength=SendingPower-PathLoss
e.g, RSS=Pt-Pl(d0)-10*η*log10(dist/d0)
Pt:transmit power
pl(d0):the pass loss for a reference distance of d0
ηis the path loss exponent
above parameters are saved in ../Parameters_Of_Models.mat
dist:distance between sender and receiver(m)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
typical value:Pt=0-4dBm(max),Pl(d0)=55dB(d0=1m),η(2~4)=4(indoor,outdoor)

Two_degree_of_freedom_vehicle_model
说明: 如果对实际工程结构作简化处理,建立其动力学模型,并确定系统的质量、刚度、阻尼参数,便可以用多种方法建立系统的动力微分方程。常用的方法有直接 法、影响系数法、拉格朗日法以及有限元法等。拉格朗日法是从能量的观点建立系统的动能T、势能U和功W之间的标量关系,是研究静、动力学问题的一种方法。如果在选定运动坐标以后,能够设法求得坐标相对应的质量矩阵和刚度矩阵,就可以用影响系数法建立多自由度系统运动微分方程[4]。本文采用拉格朗日法建立了1/4车辆几何模型。(If the actual engineering structure is simplified, its dynamic model is established, and the mass, stiffness and damping parameters of the system are determined, the dynamic differential equation of the system can be established by various methods. The commonly used methods are direct method, influence coefficient method, Lagrange method and finite element method. Lagrange method is a method to study the static and dynamic problems, which is to establish the scalar relation among kinetic energy t, potential energy u and work W from the point of view of energy. If the mass matrix and stiffness matrix corresponding to the coordinates can be obtained after the motion coordinates are selected, the differential equation of motion of the multi degree of freedom system can be established by the influence coefficient method [4]. In this paper, 1 / 4 vehicle geometry model is established by Lagrange method.)
