Abstract: In order to work out a programming method regardinglarge cylindrical objects bundled reinforcing work，a specific transportation company is taken as an example，which is responsible for the transportation of the large cylindrical objects.According to the related theory of mechanical production workmanship and the elastic-plastic，the six-free degree binding and reinforcing principle was set up.Combining with the characteristics of the transport objects and the condition of using daily-used reinforcing tools，a binding and reinforcing principle was worked out，which was in the shape of the character “eight” in Chinese.According to the actual size of vehicles and transport objects，simple treatment was provided.The Solidworks software was applied to set up a three-dimensional geometric model.A variety of inertia stress and the corresponding failure mode were analyzed，which occurred with the running vehicle’s saddles and transport objects，and the lowest strength was checked such that the binding and reinforcing objects are supposed to have，and the specific type of the binding and reinforcing objects were selected.The result show that it is very effective to bind and reinforce the objects by using the method，including establishing criteria，making plans，establishing models and checking strength.
