| 摘 要： | 针对中小型渔船起网工作效率低、安全生产事故频发等问题,研制了五轮起网机。为确定该机的最佳工作参数、探究五轮起网机的工作性能,介绍分析了该起网机的工作原理和摩擦鼓轮的受力情况并建立其载荷的数学模型,确定了摩擦鼓轮与网纲间摩擦力及摩擦矩的计算方法;利用Pro/E的变量化设计和实体造型技术,建立了该机的三维实体模型,实现了整机各组成部分的建模及装配,并通过干涉分析验证了机构设计的合理性;然后利用无缝接口软件Mechanism/pro将整机三维模型映射入ADAMS环境中进行动力学仿真分析。通过对不同马达转速、摩擦鼓轮与网纲间摩擦系数以及网纲与摩擦鼓轮的包角分析,确定该机最佳工作参数为:马达转速110 r/min,起网速度25 m/min,摩擦鼓轮摩擦系数0.4,网纲与船舷的夹角小于70°。利用Adams/Vibration模块对该机进行振动特性分析,搞清了振动较大的频率范围为30~40 Hz。所得结论为提高该机工作性能及参数优化提供了依据。

| Abstract: | In order to solve the problems of low work efficiency and frequent accidents of production safety for small- and medium-sizefishing vessels,a five wheels-net hauler was developed. In order to confirm optimum working parameters and working performance of five wheels-net hauler, working principle and force load of friction hub wheel were introduced and analyzed and the mathematical model was determined.The friction and frictional torque between the friction hub wheel and bush rope were ascertained. By applying variational design and solid modelling technology of Pro/E, the three-dimensional mode of five wheels-net hauler was established,which achieved the modelling and assembling of various components of entire hauler body. The rationality of mechanism design is verified by interference analysis.Then,the 3D model of the whole body was mapped into the ADAMS environment by using the software Mechanism/pro for dynamic simulation analysis. Based on the analysis of speeds of different motors,friction coefficient and wrapping angle between friction hub wheel and bush rope,the optimal working parameters of the machine were determined: 110 r/min for motor speed,25 m/min for hauling speed,0.4 for friction coefficient of friction hub wheel,less than 70° for the angle between bush rope and shipboard.All parameters meet the specification and stable performance.The best work parameter for the five wheels-net hauler is Using Adams/VibrationVibration module to analyze the vibration characteristic of five wheels-net hauler, the frequency range for strong vibration was 30-40 Hz. These conclusions obtained has laid the foundations for improving working performances and parameters optimization of five wheels-net hauler. |
