Static Analysis and Research on Turnover Lifting of Front Shield of Shield Machine

Abstract：Taking the front shield of shield machine as the research object， analyzes and studies its turnover hoisting stress， deduces the stress function and change law of each lifting rope and obtains the force function of each lifting lug. The load function of each lifting lug is applied by using the ANSYS Workbench software， and the finite element static simulation analysis is carried out， which verifies that the strength and stiffness of each lifting lug meet the use requirements and provides a reference calculation method for the turnover hoisting of large equipment such as shield.

Keywords：front shield; turnover lifting; lifting rope; lifting lug; static analysis
