Best mounting position of cab tilting cylinder for heavy duty cab


        Heavy duty cab is usually tilted by hydraulic cabin tilting pump driven hydraulic cylinder mounted below the front part of cab,the mounting position of the hydraulic cabin tilting cylinder has great influence on the portability and reliability of the tilting process.through the theoretical derivation,the best installation position of the lower mounting point of the hydraulic cabin cylinder with the longest arm of force in the initial state is found,Some examples are given and the CAE software ABAQUS is used to conduct the finite element analysis of the floor stringers before and after the optimization of installation location of hydraulic cabin tilting cylinder.The results show that the optimized installation location improves the stress state of the floor strings.The case study shows that the method to find the optimal installation location of tilting hydraulic cylinder of heavy duty cab is correct and effective.
