.. _V2.01.021: **v2.01.021** SDLD21 - Spring mass system with 8 degrees of freedom with viscous damper ============================================================================================= **Summary:** This unidirectional problem consists in carrying out a harmonic analysis of a mechanical structure composed of a set of spring weights with viscous dampers and subjected to sinusoidal excitation. This structural mechanics test corresponds to a dynamic analysis of a discrete model with linear behavior. The results obtained (field of movement, speed and acceleration for different excitation frequencies) are in good agreement with the results of guide VPCS. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Mod_lisation_B Mod_lisation_C Mod_lisation_D Synth_se_des_r_sultats
