| Abstract: | For improving the reliability of folding sofa detection device. meeting the needs of technical institutions to
carry out the detection work. the method of finite element analysis was put forward, and the stress and fatigue
performance of the leg, seat and back stress unit of the device was studied. According to the stress nephogram, the
structure of the device was optimized. Durable performance of the device was simulated by using fatigue analvsis module
-Fatigue Tool. The simulation results verify the rationality of the durability design of the device. |
