| Through the universal material testing machine, Xanthoceras sorbifolia Bunge. seed shell breaking experiment was conducted by three factors and three levels orthogonal experiment. Using moisture content, loading speed and loading direction as the experimental factors, and the first time shell breaking force, displacement and shell breaking strain energy as the response indicators, the mechanical properties of Xanthoceras sorbifolia Bunge. seed were analysed.The results showed that the first time shell breaking force increased with the decrease of moisture content, and displacement and shell breaking strain energy generally showed a decrease trend with the decrease of moisture content. When loading speeds were 5,10,15 mm/min, the first time shell breaking force, displacement and shell breaking strain energy on the x axis were approximately less than those in the other two directions. The factors affecting the comprehensive shell breaking effect of Xanthoceras sorbifolia Bunge. seed in decreasing order were moisture content, loading direction and loading speed. The optimal shell breaking conditions were obtained as follows: moisture content 37.14%, x axis loading direction, loading speed 15 mm/min. Under these conditions, the first time shell breaking force was 104.445 N. |
