【Abstract】 Aiming at the folding arm of model CD250 window cleaning machine, static strength under the most adverse loading condition is analyzed with finite element method to obtain stresses distribution and verify the structural design rationality. Transient dynamic analysis is conducted under two typical work conditions of starting folding arm hoisting and lowering braking. Dynamic load coefficient is obtained and theoretical basis is provided for the design and improvement of window- cleaning machines.更多还原
