Aiming at the problem that the chassis of heavy-duty wreckers is prone to bend and fracture due to excessive stress, a layout optimization method for superstructures is proposed to avoid the stress concentration of vehicle frame. In order to reduce the maximum bending stress while avoiding the operation interference of superstructures, the objective function is constructed by using the maximum bending stress and the layout density of superstructures. This layout optimization method is solved by genetic algorithm. The simulation analysis in ABAQUS shows that the maximum bending stress on main frame of optimized heavy-duty wrecker is always within the safe range, which effectively avoids the frame damage.
