摘      要：We conducted a comprehensive study to investigate the aerodynamic characteristics and force generation of the elytra of abeetle,Allomyrina *** analysis included wind tunnel experiments and three-dimensional computational fluiddynamics simulations using ANSYS-CFX *** first approach was a quasi-static study that considered the effect ofinduced flapping flow due to the flapping motion of the fore-wings (elytra) at a frequency of around 30 Hz to 40 *** dihedralangle was varied to represent flapping motion during the upstroke and *** found that an elytron producespositive lift at 0° geometric angle of attack,negative lift during the upstroke,and always produces drag during both the upstrokeand *** also found that the lift coefficient of an elytron does not drop even at a very high geometric angle of *** a beetle with a body weight of 5 g,based on the quasi-static method,the fore-wings (elytra) can produce lift of less than 1%of its body weight.
