| Abstract: | In order to find out the reason why thea piston of the gas-liquid supercharged cutter cylinder is easy to break, bBy studying the working principle of the cutter cylinder and the fracture cross-section character, we deduce the general stress condition which causesing the piston break is deduced. And then, An examples of such failures are given, which is about the break analysis by means of mechanical calculation and finite element. At the endFinally, the design defects of the knife cylinder are summarized. |
