| Abstract: | This paper discusses the way of set-topping assembly of brake unit,analyses forces on the bolts by the assembly type,proposes the calculation method on the strength of bolts and slippage if exists between the brake unit and the bogie frame,and points out that the calculation method is able to ensure that these bolts ’ strength meet the worst operating mode of brake unit. |
