The structure and the principle of the hydraulic pull-bending machine based on electrohydraulic servo system were introduced. And the design of the stretching force in the system was mainly addressed.
介绍了液压拉弯机的结构和液压原理,着重阐述了用电液伺服系统控制拉伸油缸拉紧力的设计过程。
Walking in high heels increased the normal torque forces at the knee by an average of 23%, which imposed a greater stretching force through the lateral knee ligaments.
穿高跟鞋让膝关节承受的压力平均增加了23%,膝盖韧带外侧承受了更大的压力。
The results showed that the shape of the stretching force curves corresponds to the drawing processes. It can show the film stretching behaviors and the film properties.
结果表明:薄膜拉伸力曲线的形态与设定拉伸工艺相对应,并能够反应出薄膜的拉伸过程及薄膜性能。
