As an example, the structural performance of the gear interlocking single cylinder pin mechanism is studied in depth, and a set of relatively complete design calculation is formed. The main work of the parameter optimization method is as follows: (1) the design requirements of the gear interlocking single-cylinder pin mechanism are put forward. Taking the single-cylinder bolt mechanism of the TZM1200t telescopic jib crane as an example, the structure form of the mechanism is determined through analysis. In the principle of transmission, the relevant parts of the whole mechanism are calculated in detail, and the core parameters determining the working performance of the gear interlocking single cylinder pin mechanism are determined. (2) the dynamics simulation of the gear interlocking single cylinder pin mechanism is carried out. The influence degree of each factor on the core performance parameters of the mechanism is considered, and the results under the influence of different factors are extracted, and the main influencing factors and the secondary influencing factors are determined. (3) based on the evaluation results of the influencing factors of the mechanism working process above, the main factors are extracted and the secondary factors are ignored. The dynamic equations of the cylinder pin and the arm pin are established, and the variation curves of the core performance parameters are drawn. And compared with the simulation results to verify the correctness of the equation for engineering design to provide a simple and fast calculation method. (4) the established dynamic equation parameters are analyzed to determine the main impact parameters. Drawing the curve of cylinder pin and arm pin bolt time changing with the stiffness of each drive spring, pointing out the direction of design optimization for the designer; (5) according to the direction pointed out above, aiming at the cylinder pin spring of gear interlocking single cylinder pin mechanism, Cylinder pin cylinder spring, arm pin spring and gear-rack transmission mechanism are optimized with multi-objective, and the optimized parameters are brought into the established dynamic equation, the time of bolt is extracted, and the graph is drawn. The percentage of mechanism performance improvement before and after optimization is compared and the original design structure is improved according to the optimization results. To sum up, this paper puts forward a complete design optimization method of gear interlocking single cylinder pin mechanism, which provides theoretical basis for practical engineering application and has guiding significance.
