为了深入研究层流冷却器倾翻系统运动特性,需建立准确的机-液联合仿真模型。根据倾翻系统使用要求,设计了整体结构及其液压系统;基于ADAMS和AMESim软件平台,建立了层流冷却器倾翻系统机-液联合仿真模型,分析了液压缸的负载、流量、速度及旋转接头受力等变化规律;针对倾翻系统的非对称性结构设计进行了参数优化,确定了液压缸铰接点与旋转接头1铰接点垂直投影距离为456 mm时旋转接头受力之差为零,优化了倾翻系统的运动特性,为标准件的选型提供了理论依据;通过出口节流调速的方式对倾翻速度进行调节,降低了倾翻系统在运动过程中速度及负载的波动,通过现场应用验证了联合仿真模型的正确性。

In order to deeply study the motion characteristics of the laminar flow cooler tipping system,it is necessary to establish an accurate mechanical hydraulic joint simulation model.According to the requirements for the use of the tilting system,the overall structure and hydraulic system were designed.Based on the ADAMS and AMESim software platforms,a mechanical hydraulic joint simulation model for the laminar flow cooler tilting system was established,and the changes in load,flow rate,speed,and rotating joint force of the hydraulic cylinder were analyzed.The parameter optimization was carried out for the asymmetric structural design of the tilting system,and it was determined that when the vertical projection distance between the hinge point of the hydraulic cylinder and the hinge point of the rotary joint 1 was 456 mm,the difference of the force on the rotary joint was zero,which improves the motion characteristics of the tilting system and provides a theoretical basis for the selection of standard components.By adjusting the tilting speed through outlet throttling speed regulation,the speed and load fluctuations of the tilting system during movement are reduced.The correctness of the joint simulation model is verified through on-site application.
