设计一种新型的砂带磨削机构，该机构采用伺服电机、螺母丝杆与弹簧的结构，实现了航发精锻叶片边缘的浮动磨削加工。基于Adams仿真软件平台，对新型砂带磨削机构进行仿真，得到接触力曲线。根据接触力曲线，采用均匀实验设计方法，优化砂带磨削机构的弹簧刚度系数、弹簧阻尼系数与导杆阻尼系数，优化后的新型砂带磨削机构的接触力稳定时间降低到0.1s内，且其接触力最大振动幅值较小，证明了文章设计的新型砂带磨削机构具有较好的接触力动态响应特性。%To achieve the floating and grinding of the blade edge of Aeroengine precision forging, a new belt grinding mechanism which mainly consists of servo motor, screw-nut pair and the spring structure is de-signed. Based on software platform of Adams, the contact pressure curve through simulating of the new belt grinding mechanism is obtained. According to the contact pressure curve, using uniform experimental de-sign, optimizing the coefficient of spring stiffness, spring damping,guide rod damping, reduced the stable time of contacting pressure to 0. 1 seconds after optimized new belt grinding mechanism, and the maximum vibration amplitude of the contact pressure is small than others, it proved that the design of the new belt grinding mechanism has good dynamic response characteristics of contact pressure.
