It using the example of beer incasing equipment, the problem of kinematic analysis and optimization of double four-bar mechanism is discussed. 以啤酒装箱机为例,探讨了啤酒装箱机双四杆机构的运动分析及其优化问题。
The Design of Auto-incasing Equipment 自动装箱机的设计
At places where ground fracturing is very active, pipes should be laid incasing and at the joints, flexible connection should be adopted as much as possible. 在地裂缝活动非常活跃的地方管道应敷设在套管内,节点尽量采用柔性连接。
