研究人员发现280幅距今2.6万年的旧石器时代岩刻新美星获专利，用仿真补偿冲瓶机回转支架的热变形
11月6日，新美星（300509）的发明专利《一种冲瓶机回转支架抗热变形的加工方法》获授权，申请号为CN202310740372.7。
生产线上的冲瓶机要在受热条件下维持支架工作面的位置。方案先给初始支架建模，用有限元仿真判断受热后工作面会朝哪个方向移动、平均移动多少，再据此调整结构或安装安排。完成模型修正后，零部件按调整后的尺寸加工，并在修正后的位置组装。加工依据由初始图纸变成考虑热变形之后的模型。
截至此次授权消息披露时，新美星今年获得的各类专利授权共42项，比上年同期减少22.22%。在2026年上半年，公司研发投入为3241.78万元，同比增长7.95%。企业知识产权记录中，江苏新美星包装机械股份有限公司名下可查到1313条专利信息和58条著作权信息。
