组合方法

After analyzing and comparing, the method in reference (1) is improved. The whole boom, including jibs, is simplified as a combined structure and the rigid jibs and flexible ropes used on boom frame are analyzed and treated. Influences of adopting overlapping principle in force equation on calculation results of last inner forces in rigid jibs and flexible ropes are described.
