| Abstract: | Take the support equipment for track subgrade dynamic response field test as the research object, the maximum support reaction forces determined by excavator hydraulic cylinders and backward condition are studied and the related mechanical models are established with analytic geometry and theoretical mechanics. We used a type of excavator as an example to get the optimization calculation of extended length of the hydraulic cylinders with multi-objective optimal genetic algorithm and obtained a set of Pareto solutions for the maximum support reaction force and then analyzed its stability. The results show that the support reaction force provided by the excavator can meet the requirements of the test device that it can work stably. |
