对随机参数桁架结构在随机外界温度场作用下的分析方法进行了研究.基于有限元方法
利用随机因子法建立了桁架结构的物理参数、几何参数和外界温度场分别或同时具有随机性时的结构有限元方程
应用求解随机变量函数统计矩的代数综合法对结构响应(位移和热应力)的数字特征计算表达式进行了推导.通过数值算例
分析了各种随机参数的随机性对结构位移和热应力响应的影响
并验证了文中模型和方法的合理性与可行性.
The finite element analysis method for truss structures with random parameters under random external temperature field was studied.The structural finite element equations which considered the randomness of structural physical parameters
geometry parameters and external temperature field respectively or simultaneously were established by using the random factor method.The computational expressions of the structural displacement response and thermal stress response were deduced by using the algebra synthetic method to obtain the statistical moments of random variable functions.Through a numerical example
the influences of the randomness of various random parameters on the structural displacement response and thermal stress response are analyzed
and the rationality and feasibility of presented model and approach are validated.
