Xác minh thực nghiệm và số học về phân nhánh và hỗn loạn trong hệ thống va chạm cam-đẩy
Tóm tắt
Trong bài báo này, chúng tôi trình bày thiết kế, mô hình hóa và xác thực thực nghiệm một bộ thử nghiệm cam-đẩy mới nhằm phân tích các hiện tượng phân nhánh và hỗn loạn trong các hệ động lực học mảnh ghép với va chạm. Kết quả thực nghiệm được trình bày cho một hệ thống cam-đẩy được đặc trưng bởi một cam dạng tròn và một đẩy mặt phẳng. Dưới sự thay đổi tốc độ quay của cam, đẩy được quan sát thấy tách rời khỏi cam và sau đó xuất hiện hành vi va chạm tuần hoàn được đặc trưng bởi nhiều cú va chạm và hiện tượng rung. Những thay đổi tiếp theo về tốc độ cam gây ra sự chuyển tiếp đột ngột đến hành vi dường như không tuần hoàn. Những kết quả này được so sánh với mô phỏng số học của một mô hình toán học của hệ thống, cho thấy cùng một hành vi định tính. Sự tương thích định lượng xuất sắc được tìm thấy giữa các kết quả số học và thực nghiệm.
