摘　　要：连杆裂解加载速度是影响裂解质量的重要参数之一,为了了解连杆裂解机床的加载速度特性、实现加载速度的优化,本文进行了虚拟样机仿真研究。首先,利用ADAMS/View和ADAMS/Hydraulics模块建立裂解机床机械和液压系统模型;其次在MATLAB/Simulink模块下建立控制系统模型,包括恒定输入控制系统和基于位移反馈信号的输入控制系统;最后,设置好仿真参数,完成动态仿真,根据仿真结果,分析了裂解加载速度特性。仿真结果表明:恒定输入控制时,裂解缸加载速度为118mm/s,既有利于裂解质量的控制,又不至于导致液压系统设计不合理;基于位移反馈信号时,椭圆输入控制曲线对于控制裂解油缸后程减速效果最为明显。对于实际液压油缸,可参照该曲线进行加载速度控制。The loading speed of the connecting rod fracture splitting （FS） machine is one of the important factor affecting the FS quality. In order to investigate the FS machine loading speed characteristics to realize the optimization of loading speed, the virtual prototype simulations were performed. A mechanical and hydraulic model was built for the FS machine using ADAMS/View and ADAMS/Hydraulics modules. The control system models were built for the constant input control system and the input control system with displacement feedback signal. The simulation parameters were set, and the dynamic simulations were accomplished. The loading speed characteristics were analyzed based on the simulation results. In the constant input simulations, it was found that the FS cylinder loading speed 118 mm/s was good for FS quality control as well as for the hydraulic system design. In the displacement feedback input simulations, it revealed that the elliptic input control curve made the most obvious deceleration during the latter half of FS cylinder stroke. The actual loading speed of FS cylinder can be controlled according to the above mentioned curve.
