Mechanical analysis and simulation of colliding damage of castor capsule

Abstract

Mechanical damage of castor capsule is the main problem in castor processing. In the study, the effects of different factors on the collision deformation and equivalent stress of castor capsule are discussed. A hybrid collision mechanics model of the castor capsule was established and the simulation of its collision was studied. The results show that as the collision continues, the velocity and acceleration of the collision are nonlinear. Based on the Optimal Space Filling (OSF) and Multi-Objective Genetic Algorithm (MOGA), the related parameters are determined. The result was that the hull part curvature was 340 mm, the shelling part thickness was 1.6 mm, and the collision speed was 6.96 m/s. The maximum equivalent stress at this time was 0.28 MPa, and the total deformation was 28.52 mm. The paper can provide a reference for the best design of castor capsule shelling equipment.
