Beam - spring model can simulate the tie - in by predigesting the tie - in of lining to three springs including axial spring , tangent spring and resisting bending spring , but there is a defect that it can " t simulate the partiality of bolt in lining ( 2 )梁?弹簧模型可以通过将管片接头处简化成三个弹簧:轴向弹簧、切向弹簧及抗弯弹簧来模拟接头,但是它本身存在一个缺点就是无法模拟实际中管片上螺栓的偏心情况。
To overcome the serious weakness representing cloth properties simply of previous model , the improved mass - spring model considers mechanical properties of cloth such as stretching , shearing and bending with different stiffness of spring , which can improve the realistic effect 改进的质点-弹簧模型克服了原有模型对织物的材料性能表达单一的缺点,考虑了拉伸、剪切、弯曲等力学性能对布料外观的影响,有效提高模拟的真实感效果。
