Tóm tắt

Mô hình chất lỏng ngược của kết cấu rãnh V đã được thiết lập bằng phần mềm SOLIDWORKS. Các kết cấu sắp xếp sinh học và đối xứng cùng với các gradient kết cấu 3°, 5°, 7° và 9° đã được mô phỏng bằng phương pháp phần tử hữu hạn FLUENT. Công nghệ gia công bằng laser femtosecond được sử dụng để quét kết cấu hình chữ V lên bề mặt chi tiết hợp kim YT15, đảm bảo mức chiếm dụng khoảng 10%. Các tính chất ma sát của mặt cắt dụng cụ được đánh giá thông qua các thí nghiệm ma sát, mòn và cắt. Qua so sánh, nhận thấy rằng hiệu ứng bôi trơn động học của kết cấu V hình sinh học tại gradient 7° là lý tưởng nhất. So với bề mặt không có kết cấu, hệ số ma sát giảm khoảng 20%, và tỷ lệ mòn giảm xuống còn 0.005–0.015. Hơn nữa, tốc độ dòng chất lỏng là nhanh, điều này mang lại khả năng giảm lực kéo và chống mòn tốt hơn.
