通过具有随机结构参数的四分之一车辆模型研究了具有不确定性结构参数的车辆在受到来自道路的随 机激励作用下的振动响应问题。将簧上质量、簧下质量、悬挂阻尼、悬挂刚度以及轮胎刚度均认为是随机变量。将路面的不平整引起的对车辆的激励看作高斯随机过程并通过简单指数功率谱密度来建立力学模型。(By a quarter vehicle model with random parameters studied vehicle structure uncertain structural parameters of the vibration by the random excitation the road response under question. The sprung mass, unsprung mass, suspension damping, suspension stiffness and rigidity of the tire are considered to be random variables. The excitation caused by uneven road vehicle regarded as Gaussian random process and to create a mechanical model of a simple exponential power spectral density.)

Matlab求解微分方程组，几种经典算法(MATLAB Solves Differential Equations, Several Classical Algorithms)

可以进行简单的数学运算：加、减、乘、除,sin(),cos(),tan()等，还可以对数字进行取余和开方的运算。但仅限于十进制下，还可以进行数的正、负之间的相互转换，exit表示退出, clear表示初始化，有一个 TextField用于显示传来的计算结果；Server端用于监听连接请求、计算发送过来的两数的和、送回数据结果。(Can perform simple arithmetic: add, subtract, multiply, divide, sin (), cos (), tan (), etc. can also figure to take over and prescribing arithmetic. But only under the metric system can also be used for a number of positive and negative between the conversion, exit, said exit, clear that the initialization, there is a TextField to display the results from the calculation Server client connection requests for eavesdropping, calculated sent the two and the number of returned data.)
