摘要
基于猪笼草叶笼滑移区表面特殊结构与良好滑移功能仿生研制致灾农业昆虫捕集滑板过程中,需要测试昆虫在仿生原型及制备滑板表面的附着力、摩擦力等毫牛尺度微力。为满足毫牛尺度微力的测试需求,依据离心力原理设计研制了一种离心式昆虫微力测试系统。该系统主要包括测试平台及附属机构、调速电机及转速控制器、视频监控系统和能够实现各部件固定安装的机座等4部分。调试运行结果表明设计研制的离心式昆虫微力测试系统能够准确采集蚂蚁、甲虫、飞蛾等体型较小昆虫附着系统产生的毫牛尺度微力,精度可达0.1mN,能够满足致灾农业昆虫捕集滑板仿生研制过程中对昆虫微力准确测试的需求。
During biomimetic designing and manufacturing process of insects trapping plate based on special surface structures and great sliding function of slippery zones in Nepenthes pitchers, the attachment force, friction force of insect on biomimetic prototype, and manufactured slippery trapping plates are needed to be measured accurately. To satisfy the demand of measuring the force with mN magnitude, we designed centrifugal insect micro-force measuring system based on centrifugal principle. This system consists of measuring platform and its affiliated mechanical structure, electromotor and its speed regulator, video moni- toring system, and baseframe utilized for fixed mounting mechanical parts. The experimental results confirmed that the centrif- ugal insect micro-force measuring system can accurately measure the force with mN magnitude generated by the attachment sys- tem of insects, such as beetle, ants and moths. The measuring accuracy of this system can reach to 0.1 mN, therefore com- pletely satisfy the demand of accurate measuring insect force during biomimetic designing and manufacturing process of insects trapping plate used for controlling agricultural pest.
