项目摘要

In this work, the vehicle suspension and the vehicle bumper are proposed as two possible practical applications of the colloidal damper (CD), and its dynamic characteristics are investigated from a practical point of view. Concretely, based on a compact design of the CD, the real product destined to vehicle suspensions and/or bumpers was manufactured. In order to increase the damper's life, the colloidal solution is introduced inside of a tank that is separated by a filter from the main cylinder, in which only water was supplied.On one hand, in order to investigate the damping abilities of such novel machine element, in this work, 3 types of absorbers destined to vehicle suspension are considered: used oil damper (after 100,000 km travel distance), unused oil damper (0 km travel distance) and the new designed CD. Firstly, all these absorbers were experimented under sinusoidal vibrations on a classical fatigue test rig. Results obtained demonstrate that the CD can be successfully employ … More ed for vehicle suspensions both with and without a compression coil-spring mounted in parallel; certainly, when the spring is omitted, the vehicle's suspension becomes simpler and lighter. Then, all 3 types of absorbers described previously were mounted on the body of a real car and the vibration measurement equipment was installed. Travel tests of the auto-vehicle on joy-steps and half-sinusoidal steps were performed, and the car's ride-comfort factors, as well as the transmissibility factor of vibrations from the rough pavement to the car's drive-shafts were evaluated. Results obtained demonstrate that the aging-process of the oil damper produces an augmentation of the car's ride-comfort factor and also of the transmissibility factor. For the CD subjected to tests in this work, the results obtained were intermediate to those obtained for the unused and used oil dampers. However, for all 3 types of absorbers, subjected to various travel speeds, the car's ride-comfort factor varied in the range 10-100; accordingly, when the riding-time interval increases over 1hour, the vehicle's passengers might fell sick and their concentration abilities are badly affected. Here, only tests with the CD mounted in parallel to a compression coil-spring were performed, but during the future developments of this work, CD will be tested without the usual attached spring. Moreover, by trying different types of silica gel and by adjusting the pre-pressurization to achieve an efficient control of the damping rates one expects a reduction of the car's riding-comfort factor in the range 1-10, i.e., in the interval without vibration-induced sickness.On the other hand, in this work a collision test rig (barrier type) that incorporates in its structure a CD was designed and manufactured. Instead of a real vehicle a radio-controlled car equipped with a gasoline engine type (car weight: 5.8kg, maximum travel speed: 60km/h) was employed. Such mini-vehicle was guided toward the collision test rig by using a piano-wire. Collison measurement equipment was installed and the CD damping ability relative to the kinetic energy of the car was estimated. Based on such results it became possible to calculate the safety factor of tested vehicle at frontal collision. Less
