从塑料双壁波纹管环刚度的定义出发,针对广泛生产的梯形波纹状PE/PVC塑料双壁波纹管,运用CAD软件分析管道纵截面的惯性矩,从而计算其环刚度。并与实验测试所得的环刚度进行比较分析后,运用VC++软件开发出塑料双壁波纹管的环刚度检验系统。
Based on the definition of plastic double-wall corrugated pipe ring stiffness, the ring stiffness was calculated by analyzing the moment of inertia of longitudinal section of pipe using CAD software for the widely produced trapezoidal corrugated PE / PVC plastic double-wall corrugated pipe. And compared with the experimental ring stiffness obtained after the test, the use of VC + + software developed a double ring bellows plastic ring stiffness test system.
