摘  要:
为了克服传统小麦收割机设计过程中反复试验-制造的长周期与低效率的缺点,且达到降低机械设计成本的目的,提出了一种基于离散元虚拟技术的小麦收割机虚拟样机设计方法,实现了小麦收割机的虚拟优化设计。采用Windows平台下VS2010集成了离散元仿真软件,并使用Open GL软件仿真实现了脱粒过程的三维显示,利用并行计算的方法对数据进行处理,最后通过保存三维输出结果,对脱粒的性能进行了数据统计和计算。虚拟仿真测试表明:所提出的小麦植株建模方法和收割机虚拟样机的性能仿真是可行的,通过颗粒捕捉仿真得到了麦粒的运动轨迹,并根据对脱粒的性能进行了统计,最终得到了小麦收割机脱粒的损失率、破碎率和脱净率,对现代化农机的设计制造具有重要的现实意义。

摘  要:
In order to overcome the disadvantages of long period and low efficiency shortcomings in traditional wheat harvester design process of repeated experiments-manufacture,save the cost of the mechanical design,it put forward a wheat harvester virtual prototype design of discrete element method based on virtual technology,the virtual design and optimization of wheat harvester. The use of Windows platform VS2010 integrated discrete element simulation software,and use the Open GL software simulation to achieve a three-dimensional display of threshing process by using parallel computing method,data processing,and finally through the preservation of the three-dimensional output,the threshing performance of data statistics and calculation. Through the simulation test shows that the performance simulation of the proposed modeling method and wheat harvester virtual prototype is feasible,the particle capture are simulated trajectories of wheat,and the track performance of threshing were collected,finally got the wheat threshing loss rate,broken rate and off the net rate of design of modern agricultural machinery manufacturing,which has important practical significance.
