为了分析船用多功能数控机床关键滑块导轨运动副在舰船波浪载荷摇荡环境下的结构特点,结合机床的结构特点和舰船波浪载荷摇荡环境,确定了机床的运动坐标系和机床关键滑块导轨运动副的舰船运动方向一致性布局方案。依据舰船结构稳定性设计要求,并采用机床导轨设计方法,得到了滑块导轨的极限额定横摇载荷参数和运行参数,并分析确定了导轨滑块最大负载状态。基于导轨滑块的载荷参数分别采用静态校核算法和动态响应方法,分析了滑块导轨运动副的结构稳定性特点,结果表明:在舰船横摇环境下,船用多功能数控机床关键滑块导轨运动副具备较高的结构静态稳定性和动态稳定性。
In order to analyze the structural characteristics of the key slider guides of marine multifunctional CNC machine tool under the wavy load of ship, combining with the structural characteristics of the machine tool and the wobbling environment of ship wave load, the motion coordinate system of the machine tool and the key slider Rail movement deputy ship direction consistent layout of the program. According to the design requirements of ship structure stability and the design of the guideways of the machine tool, the ultimate rated rolling load parameters and operating parameters of the slider rail are obtained, and the maximum load status of the rail slider is analyzed. Based on the static checking algorithm and the dynamic response method, the structural stability of the sliding pair’s guide rail is analyzed based on the load parameters of the guide rail slider respectively. The results show that the critical sliding block of the marine multifunctional NC machine tool Rail sports deputy with a higher structural stability and dynamic stability.
