| 摘 要： | 以增力较大的肘杆机构为对象,分析了普通直线连杆-等长肘杆和三角连杆-不等长肘杆两种机构的工作特性,建立了它们的动力学和运动学模型。以4000kN伺服压力机为例,采用MATLAB仿真软件对伺服机械压力机传动机构进行了运动学-动力学仿真分析。分析结果表明,三角连杆-不等长肘杆与直线连杆-等长肘杆相比具有更好的动力学和运动学特性:在同等公称压力条件下,三角连杆-不等长肘杆的输入扭矩较直线连杆-等长肘杆的输入扭矩小70.6%,而公称压力行程内前者的平均速度约为后者平均速度的50%。

| Abstract: | Knuckle mechanisms have large force gain.The working properties of strait link-knuckle and triangle link-knuckle mechanisms were analyzed and their mathematic models were built up herein.Taking 4000kN servo press as example,the numerical simulations were conducted.The simulation results show that the triangle link-knuckle mechanism has better kinetic-dynamic characteristics.In comparison with common strait link-knuckle mechanism,the required torque reduces by 70.6% and the average velocity of the slide within the nominal pressure stroke reduces by 50% with the same nominal pressures. |
