摘　　要：在数值计算领域求解大型常微分方程组时通常采用分解算法,类似地,在多学科协同仿真中系统模型往往被拆分成多个子模型并采用多个求解器进行求解。基于以上相关性,研究了多学科协同仿真算法的基本原理,在微分方程组合算法的基础上提出了基于联合仿真步的组合算法,给出了算法的形式化描述和原理说明,并通过一个具体实例验证了算法的有效性。It is common to use decomposition methods to solve large ordinary differential equations in numerical calculation. Similarly, system model is often divided into several sub-models and solved by several solvers in multidisciplinary collaborative simulation. Based on this correlation, basic idea of algorithm for multidisciplinary collaborative simulation was studied. Combinative algorithm based on united simulation step was proposed based on combinative algorithm for ordinary differential equations. Formalized description and theoretical illustration of the algorithm were given. Finally an example was used to check validity of the algorithm.
