The invention relates to the technical field of measurement tests, and discloses a drop impact test platform system for measuring the buffer performance of a shock absorber. The system comprises a base, a balance weight device, an adjusting device, a lifting rope, a locking and releasing device, a lifting hook, a lifting device, a control box and an acceleration detection device, the shock absorber is arranged at the bottom of the balance weight device, the balance weight device is connected to the releasing device through the lifting rope, and the adjusting device is used for adjusting the initial falling posture and position of the balance weight device; the locking and releasing device is connected to the lifting hook through a connecting piece and switched between the locking balance weight device and the releasing balance weight device, the lifting hook is connected with the lifting device, the control box controls the lifting device to move to change the vertical height of the lifting hook, and the acceleration detection device is arranged on the shock absorber; and the acceleration of the shock absorber is detected under the condition that the counterweight device is released and falls freely, and the released counterweight device finally falls onto the base. Therefore, the shock test of the shock absorber under various shock or vibration loads can be realized.
Description
technical field [0001] The invention relates to the technical field of measurement and testing, in particular to a drop impact test platform system for measuring the cushioning performance of a shock absorber. Background technique [0002] The shock absorber is one of the key components of the vehicle. It is mainly used to buffer and isolate the impact and vibration load between the vehicle and the ground or the track, so as to ensure the stability, comfort and safety of the vehicle during operation. On the other hand, the shock absorber also needs to support the main load of the vehicle and have sufficient rigidity. [0003] In order to verify the cushioning efficiency of the shock absorber and at the same time verify the structural rigidity of the shock absorber, it is necessary to conduct an impact test experiment on the shock absorber. [0004] Usually, the test equipment can be provided with a certain intensity of shock or vibration excitation through the vibrator. Ho...
