Chassis And Method Of Designing Main Beam For Same

摘要

A method for designing a main body of a trailer, trailer chassis, or like transportable load-supporting system includes selecting a known design of a transportable load-supporting system's main frame. The method includes developing a monocoque main beam having moments of inertia that are respectively greater than or substantially equal to the moments of inertia of the known main frame. Deflections of the known main frame and of the monocoque main beam in response to application of a torsional load, a vertical load, and a lateral load are then determined. Cross-members can be added to the monocoque main beam until the deflection of the monocoque main beam is less than or substantially the same as the deflection of the known main frame. A monocoque main beam designed according to the method is also disclosed.

1. A method for designing a main body of a trailer, trailer chassis, or like transportable load-supporting system, the method comprising:
selecting a known design of a main frame of a transportable load-supporting system that complies with industry standards regarding gross weight capacity; developing a monocoque main beam having a polar moment of inertia, a vertical bending moment of inertia, and a lateral bending moment of inertia that are respectively greater than or substantially equal to a polar moment of inertia, a vertical bending moment of inertia, and a lateral bending moment of inertia of the known main frame; obtaining a deflection of the known main frame and a deflection of the monocoque main beam in response to application of at least one of a torsional load, a vertical load, and a lateral load to the known main frame and to the monocoque main beam; and adding cross-members to the monocoque main beam until the deflection of the monocoque main beam is less than or substantially the same as the deflection of the known main frame.
