Considering the load borne by the lateral loading mechanism when it applies load to the test piece,the most unfavorable load and dangerous cross-section are analyzed for the lateral loading stand,and the theoretic force calcula-tion is calculated to review the strength,rigidity,and stability.Based on working requirements on the lateral loading stand, finite element method is adopted for 3D solid modeling,pre-treatment,setup of constraint conditions,and load application of its overall structure.Through further analysis solution,strength and rigidity of the structure are checked for its consistency with design requirements.
