摘要
随着机电液系统工程的日益复杂化,如果仅依赖传统的设计方法,很难全面地进行整体分析和评估。为了更精准地实现系统设计和优化设计,需要借助先进的计算机仿真技术,通过模拟实际运行场景,来完善和优化系统的设计。而市面上的专业商业软件专业性程度高,所擅长的仿真领域往往不同,并且普遍都是单核仿真,面对复杂系统时存在仿真效率低的问题。针对以上问题,提出利用TCP/IP传输协议构建分布式仿真模型,充分利用现代计算机的多核架构使多个子任务能够同时运行,并以统一的代码形式导出,生成独立的可执行文件。通过Qt软件对液压挖掘机机电液联合仿真系统进行二次开发,编制出具有良好交互性和针对性的仿真系统。以活塞杆位移、速度仿真为例,仿真结果与原仿真结果基本吻合,证明分布式仿真设计方法的准确性。以斗杆模型仿真为例,斗杆模型在SimulationX中仿真用时3 min 54 s,仅以代码导出斗杆模型的方式仿真用时24 s,利用TCP/IP传输协议构建分布式仿真模型再以代码导出的方式用时13 s,其仿真效率分别是前两者的18倍和1.85倍。研究结果表明,对复杂机电液系统构建分布式仿真模型并以代码导出运行,方法简单、高效。
With the increasing complexity of mechatronic-hydraulic systems engineering,it is difficult to conduct a comprehensive overall analysis and evaluation relying solely on traditional design methods.To achieve more precise system design and optimization,advanced computer simulation technology is needed.By simulating actual operating scenarios,the design of the system can be improved and optimized.However,professional commercial software available on the market is highly specialized,excelling in different simulation fields,and generally operates in a single-core simulation mode,which leads to low simulation efficiency when dealing with complex systems.To address these issues,a distributed simulation model was proposed,utilizing the TCP/IP transmission protocol.This approach fully exploited the multi-core architecture of modern computers,allowing multiple sub-tasks to run simultaneously and be exported in a unified code format to generate independent executable files.The hydraulic excavator mechatronic-hydraulic co-simulation system was redeveloped using the Qt software,creating a simulation system with good interactivity and specificity.Taking the simulation of piston rod displacement and speed as example,the simulation results are basically consistent with the original simulation results,proving the accuracy of the distributed simulation design method.Taking the simulation of the boom model as example,the simulation time in SimulationX is 3 min 54 s,while the simulation time using only code export is 24 s.The simulation time using the distributed simulation model constructed with the TCP/IP transmission protocol and code export is 13 s,which is 18 times and 1.85 times more efficient than the previous two methods,respectively.The research results show that constructing a distributed simulation model for complex mechatronic-hydraulic systems and running it through code export is a simple and efficient method.
