Design and Analysis of a New Type of Multifunctional Combined Ladder

This paper introduces the design of a new type of multifunctional combined ladder, it has five functions of pedal ladder, armrest ladder, a ladder truck, chair and items to meet the diverse needs of the people. Combination ladder is to achieve a ladder with multiple func-tions through institutional change on the basic of the ladder, has the advantages of simple structure, easy to use, powerful features. In the Solidworsk combination ladder of modeling and simulation to ensure the reliability of the motion, and through the Solidworks Simulation fi-nite element analysis to guarantee the performance of the strength and stiffness, the results show that the system assembly performance, sports performance and mechanical properties can meet the various functions of the multifunctional combined ladder implementation requirements.
