通过数值模拟得到不同蹬冰角下冰刀刀片变形过程中其应力分布的规律。采用速滑冰刀形变数值模拟方法,开展冰刀前支架、后底座均施加均布载荷480N的情况下,蹬冰角分别为20°、30°、40°、50°、60°70°时,速滑冰刀应力应变的数值模拟。以S(Mises等效应力)为输出参数,研究不同蹬冰角下,速滑冰刀刀片的应力分布情况。
Numerical simulations were carried out to obtain the laws of stress distribution during the deformation of the ice blade at different stirrup angles. The numerical simulation of the deformation of the speed skating blade was carried out by using the numerical simulation method to simulate the stress and strain of the speed skating blade at the stirrup angles of 20°, 30°, 40°, 50° and 60°70° with a uniform load of 480N applied to the front support and the rear base of the blade, respectively. The S (Mises equivalent force) was used as the output parameter to study the stress distribution of the blade at different stirrup angles.
