摘　　要：按传统方法设计林木生物质粉碎机,其能耗增加、生产率降低;且细小的木屑极易堵塞筛网,带来安全隐患。将创新设计方法学——TRIZ(发明问题解决理论)应用于林木生物质粉碎机安全设计中,按照TRIZ解决问题的系统化方法,通过技术矛盾定义和创新原理应用、物理矛盾定义和分离方法应用、物场模型建立和标准解法应用等TRIZ工具,实现了高效率、低功耗、细粉碎粒度、高安全可靠性的目标。在设备的安全设计中应用TRIZ理论,可以帮助设计人员迅速发现主要问题并提供解决问题的相应原理,减少传统试错法所耗费的时间、精力,大大提高设计效率和设计安全性。The forest biomass pulverizer designed by traditional methods not only has the characteristics of high energy consumption and low productivity, but also causes potential hazards due to the fact that the wood powders can easily jam the screen grids. To overcome these problems, a creative design methodology called TRIZ （ Theory of Inventive Problem Solving） was introduced and applied to the safety design of forest biomass pulverizers. According to TRIZ, the objectives of high efficiency, low energy consumption, fine particle size and high safety and reliability can be achieved by solving such puzzles as the definition of technical contradiction and the application of creative principles, the definition of physical contradiction and the application of separation method, and the establishment of substance-field model and the application of standard solving methods. The application of TRIZ theory in the safety design of equipment can help the designer quickly discover the main problems, get countermeasures and improve the design efficiency and safety by reducing the time and energy needed for traditional methods.
