Abstract
An embodiment of the present invention relates to a method of manufacturing a vehicle body. The method includes coupling a frame assembly to a platform, wherein the platform is in a cambered and unloaded condition, and wherein the frame assembly has a degree of play at coupling points with the platform and securing the coupling points to eliminate the degree of play and thereby to provide substantially zero residual stress in the vehicle body in the cambered condition.
Claims18
A method of manufacturing a vehicle body, comprising:
- coupling a frame assembly to a platform, wherein the platform is in a cambered and unloaded condition, and wherein the frame assembly is in a flat and un-cambered condition, the step of coupling the frame assembly to the platform including:
- breaking a tack weld between at least one frame member of the frame assembly and a slip joint plate of the frame assembly to permit a degree of play between the at least one frame member and the slip joint plate;
- sliding the slip joint plate relative to the at least one frame member to place the slip joint plate in flat registration with the platform at coupling points with the platform;
- securing the slip joint plate to the platform;
- and securing coupling points between the slip joint plate and the at least one frame member to eliminate the degree of play between the slip joint plate and the at least one frame member and thereby to provide substantially zero residual stress in the vehicle body in the cambered condition.

A method of manufacturing a rail vehicle body, comprising:
- coupling a rail vehicle frame assembly to a rail vehicle platform, wherein the platform is in a cambered and unloaded condition, and wherein the frame assembly is in a flat and un-cambered condition, the step of coupling the frame assembly to the platform including:
- breaking a tack weld between at least one frame member of the frame assembly and a slip joint plate of the frame assembly to permit a degree of play between the at least one frame member and the slip joint plate;
- sliding the slip joint plate relative to the at least one frame member to place the slip joint plate in flat registration with the platform at coupling points with the platform;
- securing the slip joint plate to the platform;
- and securing coupling points between the slip joint plate and the at least one frame member to eliminate the degree of play between the slip joint plate and the at least one frame member and thereby to provide substantially zero residual stress in the vehicle body in the cambered condition.
