Failure Analysis and Optimization Design for the Support Foot Connection Structure of Portable Light
Portable light,as one of the frequently used lighting tools in outdoor work sites,are particularly important for their lightweight and portable characteristic.Based on a portable light developed,the failure reasons of the folding support foot connection structure were analyzed,a simplified mechanical model of the connection structure was established,and the theoretical strength formula of the failed component of the connection structure was derived in this paper.Based on the theoretical strength formula,the strength of the failed component of the connection structure was calculated,further verifying the failure reasons of the connection structure in theory.Finally,the failed component of the connection structure was optimized for design based on the theoretical model.The strength of the failed component before and after optimization were analyzed by numerical simulations,and the experimental test was conducted on the optimized connection structure.The results show that the optimized connection structure has improved strength,higher safety and reliability.
