摘要:
提出了用混凝土侵彻模型试验代替原型试验的方法,建立并验证了混凝土侵彻试验的相似准则。基于相似理论,推导了包括材料、弹速、着角、几何关系等因素的混凝土侵彻试验相似准则。为了验证相似准则,进行了1发原型试验和7发模型试验。由于模型试验的弹速不够接近原型试验的弹速,在模型试验数据处理中引入了灰色系统理论,建立了最大侵彻深度灰色预估模型。通过模型试验相应弹速的灰色预估值与原型试验结果的相似对比及误差分析,说明模型试验能够满足要求。
Abstract:
A method for substituting model experiments for the prototype experiments of concrete penetrat ion by rigid projectile is presented. The similarity criteria of the model experiments of concrete penetration are established and validated. Based on the similarity theory, the project ile velocity, the material of projectile and target , and the incidence angle are taken into account. One prototype experiment and seven model experiments are carried out to validate the similarity criteria. The projectile velocities of the model experiments and the prototype experiments are not proximal, so a grey pre-estimation model of maximum penetration depth is established.The va-l ues of grey pre-estimation of model experiments and the results of prototype experiments are contrasted. The sim-i larity criteria are validated through the error analysis.
