Optimize analysis of major design variables

ADAMS/View provides the function of optimization analysis, optimization analysis is for those who have more influence on the system of the design variables are optimized, under the given constraint condition to find the optimal value of them make the system to achieve optimal performance. Based on the previous parametric design, the spring z axis and stiffness are the main parameters affecting the performance of the prototype. Therefore, two design variables, z and K, are selected to optimize the minimization of the maximum driving torque. After 8 iterations, the simulation results were obtained with the optimal solution: z = 54.173 mm, K = 9.61448n/mm. The maximum driving moment was 57.209 N · m, which was 56.2% lower than before. A gurney lifting process middleman role prior to the first cross arm force is always perpendicular to the connecting rod, the biggest driving force amplitude 57.209 N · m except for the connecting rod length before, the person need to exert the most vigorously 84.6 N, you can see, very good solution to the gurney lifting process is very difficult problem. Table 1 is an iterative optimization report.

conclusion

Using the MSC \ ADAMS virtual prototype technology to carry out the dynamic simulation analysis of stretcher bed mechanism, it has the advantages of higher visualization and more accurate calculation than the traditional design method. Through the SimDesigner interface software, the seamless connection between CATIA and MSC \ ADAMS was realized, and the integration technology of design and analysis was realized.

MSC/ADAMS parametric design has been used to study function of spring design and layout of the parameters for the simulation analysis, find the main parameters that affect the performance of the prototype, reuse optimized analysis function to main influence parameters are optimized, find the optimal solution, for subsequent spring design and layout provides a very valuable reference.
