林果振动采收装备及研究方法
Vibratory harvesting equipment for forest fruits and research methods
随着机械化的发展，采用更高效的机械化采收代替人工是必然趋势。振动采收技术成为提高果实采收效率的重要手段。根据不同激振方式，和不同激振位置对振动采收装置进行分类，分析了其工作原理及应用效果。基于振动采收，国内外学者从振动采收影响因素，树体传递特性，树体动力学建模这几个方面进行研究。同时，聚焦于果实的研究，具体加速度传感器，高速摄影仪，子系统动力学建模等方法。通过对树体与果实响应的研究对采收装置进行合理的优化。并对林果采收未来发展做出展望。
With the development of mechanisation,it is an inevitable trend to adopt more efficient mechanised harvesting instead of manual labour.Vibratory harvesting technology has become an important means to improve the efficiency of fruit harvesting.According to different excitation methods,and different excitation position of vibration harvesting device classification,analysed its working principle and application effect.Based on vibratory harvesting,scholars at home and abroad research from the vibratory harvesting influencing factors,tree transmission characteristics,tree dynamics modelling.At the same time,focusing on the study of the fruit,specific acceleration sensor,high-speed camera,subsystem dynamics modelling and other methods.Through the study of the tree and fruit response to the harvesting device for reasonable optimisation.And make a prospect for the future development of forest fruit harvesting.
