1 For bogies and underframes the rolled steel bars were dealt with similarly to wagon components.

2 Terms for railway vehicle parts; underframe, underframe for diesel locomotives.

3 Then select the corresponding modules based on the underframe assembly into 3 D models.

4 Terms for railway vehicle parts; underframe, underframe for electric locomotives.

5 The small underframe structure is the main load - bearing body in tare special car.

6 A two shift system was introduced in this department to coincide with the shift working in the underframe shop.

7 That we use finite element analysis calculate to the strength and the rigidity of the bodywork structure. Thus the optimum fillet of the small underframe structure can be specified.

8 The company mainly produces automobile hub nut, screw. Round bar, horizontal bar, the well shape frame (Car underframe).

9 In addition, the external size and the weight of the underframe are effectively reduced to further facilitate transportation and installation of a whole machine.

10 According to requirement of factory and experiment, U-shaped loading method was used to analyze the seat underframe and get the deflection and stress of test point on the front longeron.

11 The impacts of transverse and longitudinal shrinkage of welding seam on underframe positioning.
