PURPOSE:To improve simulation performance by generating the torsional vibration similar to the actual vibration by connecting the first and the second swing mechanisms onto the first and the second planetary gear mechanisms, respectively. CONSTITUTION:The first and the second planetary gear mechanisms 11 and 12 are arranged onto the inner peripheral side of ring gears 1 and 2. The first planetary carrier 14 of the first planetary gear mechanism 11 is fitted onto the inner peripheral surface of a cylinder part 3a through a bearing metal 16, and a swing arm 20 is provided integrally and is connected to the first swing mechanism 18. The swinging input shaft 28 of the second planetary gear mechanism 12 is fitted in turnable ways onto the inner peripheral surface of the cylinder part 3a through a bearing 29, and the second swinging mechanism 30 is connected to the edge part of the swinging input shaft 28. A test-piece holder 33 is fixed at the edge part of the first output shaft 21. |
