Base on the mathematic model of load - deflection relationship of the rectangular membrane , micro balloon actuator ' s theory curve of pressure - deflection has been calculated and plotted . after the simplified geometric model of microactuator was set up , by utilizing ansys mooney - rivlin hyperelastic model , nonlinear structural distortion of silicone rubber can be solved 通過(guò)建立氣泡薄膜的幾何簡(jiǎn)化模型,針對(duì)硅酮橡膠的材料非線性特點(diǎn),選用了適合橡膠類材料的mooney - rivlin超彈性模型,運(yùn)用ansys軟件對(duì)這一非線性結(jié)構(gòu)變形進(jìn)行了求解。
