Materials and methods Basic thought of finite element and ANSYS software Finite element method is adopted to analyze the stacking and horizontal controlled impact working condition.
The maximum principal stress of rotational molding material box is far less than 80MPa, limit stress of rotational molding material.
The major principal stress of rotational molding material box is less than 80MPa, limit stress of rotational molding material, in accordance with stress verification standard.
Therefore, these two materials are safe in the horizontal controlled impact working condition.
