Design of Centrifugal Insect Micro-Force Measuring System

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 monitoring system,and baseframe utilized for fixed mounting mechanical parts.The experimental results confirmed that the centrifugal insect micro-force measuring system can accurately measure the force with mN magnitude generated by the attachment system of insects,such as beetle,ants and moths.The measuring accuracy of this system can reach to 0.1mN,therefore completely satisfy the demand of accurate measuring insect force during biomimetic designing and manufacturing process of insects trapping plate used for controlling agricultural pest.
