Abstract
The utility model discloses a radial fatigue testing tool for a suspension shockproof sleeve. The radial fatigue testing tool comprises a pedestal; and a test piece fixed seat and an oil cylinder fixed seat are arranged at the pedestal. An oil cylinder is arranged at the oil cylinder fixed seat; and a piston rod of the oil cylinder is connected with a reciprocating loading mechanism. A suspension shockproof sleeve is arranged in the reciprocating loading mechanism; a bolt is arranged in the inner hole of the suspension shockproof sleeve; and the bolt is also fixed at a pair of clamp plates of the test piece fixed seat. According to the scheme, a test piece loading arm is used for applying the changing load on the suspension shockproof sleeve at the radial direction by a way of linkage rod reciprocating loading mechanism; and the fatigue service life of the suspension shockproof sleeve in the vibration state can be detected with low cost and high reliability. Moreover, the price of the testing tool is appropriate; and the operation cost is low. The testing condition of the testing tool is one simulating the actual application working condition of the suspension shockproof sleeve equivalently, thereby actually reflecting the service life of the suspension shockproof sleeve.
Description
Technical field
The utility model relates to semitrailer parts dynamic fatigue test device technique field, more particularly, relates to radially fatigue test frock of a kind of suspension anti-vibration sleeve.
Background technology
Along with highway and urban transportation develop rapidly, comfort level to semitrailer or other traffic delivery means, mean time between failures has higher requirement, hanging anti-vibration sleeve is the vibration absorber of applying on semitrailer or other heavy traffic delivery means, a main power transmission, vibration isolation, the effect of buffering and location, its volume is little, lightweight, without wearing and tearing, easy to install, because it in use needs to bear alternate load, therefore, in enterprises quality control, user delivers for a check, new product evaluation, in the links such as authentication, suitablely carry out fatigue behaviour sampling observation, and at present, for this semitrailer part, also do not have unified industry to detect test standard, part producer inspects by random samples with test method and the equipment of like parts conventionally, therefore, in semitrailer industry, need to have a kind of radially fatigue test frock that is applicable to semi-trailer suspension anti-vibration sleeve, make the quality of anti-vibration sleeve obtain effective monitoring, enterprise can be at lower cost, high reliability simulation anti-vibration sleeve actual condition detects its Q-percentile life.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the suspension anti-vibration sleeve that a kind of rational in infrastructure, long service life, bilateral punching be simultaneously provided is fatigue test frock radially.
The technical solution of the utility model is: hang radially fatigue test frock of anti-vibration sleeve, comprise base, test specimen holder, oil cylinder fixing base are set on base, on oil cylinder fixing base, be provided with oil cylinder, the piston rod of oil cylinder connects round load maintainer, in coming and going load maintainer, suspension anti-vibration sleeve is set, on the endoporus that hangs anti-vibration sleeve, bolt is set, described in be bolted on a pair of clamping plate of test specimen holder.
Also comprise force cell, described force cell is arranged between the piston rod and round load maintainer of oil cylinder.
Described round load maintainer comprises test specimen loading arm, unitor, loading cover, and described suspension anti-vibration sleeve is arranged on and loads in cover, and described loading cover is fixed on one end of test specimen loading arm, and the other end of described test specimen loading arm arranges unitor.
The beneficial effects of the utility model are:
The utility model comes and goes vibrating mechanism with connecting rod mode by test specimen loading arm imposes the load of variation to hanging anti-vibration sleeve in radial direction, with low-cost, detect and hang the fatigue lifetime of anti-vibration sleeve under vibrational state to high reliability.Test unit price is suitable, operating cost is lower, and the test condition of test tool is the practical application operating mode that equivalent simulation hangs anti-vibration sleeve, can truly reflect the serviceable life of hanging anti-vibration sleeve.
Accompanying drawing explanation
Fig. 1 is that the utility model hangs radially fatigue test frock structural representation of anti-vibration sleeve.
Fig. 2 is that the utility model hangs the radially structure vertical view of fatigue test frock of anti-vibration sleeve.
Embodiment
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model provides radially fatigue test frock of a kind of suspension anti-vibration sleeve, comprise base 6, test specimen holder 5, oil cylinder fixing base 1 are set on base 6, on oil cylinder fixing base 1, be provided with oil cylinder 2, the piston rod of oil cylinder 2 connects round load maintainer, in coming and going load maintainer, arrange and hang anti-vibration sleeve 8, on the endoporus that hangs anti-vibration sleeve 8, bolt is set, on the described a pair of clamping plate 9 that are bolted to test specimen holder 5, between the piston rod of oil cylinder and round load maintainer, be provided with force cell 3.Described round load maintainer comprises test specimen loading arm 4, unitor 10, loads cover 7, and described suspension anti-vibration sleeve 8 is arranged on and loads in cover 7, and described loading cover is fixed on one end of test specimen loading arm, and the other end of described test specimen loading arm arranges unitor 10.The inner structure of oil cylinder 2 comprises rod chamber and rodless cavity (not shown), and its oil piping system is controlled by control system, realizes the movement of piston rod and the transmission of pressure.
When hanging anti-vibration sleeve radially during fatigue test frock work, control system is controlled and is made the piston rod of oil cylinder 2 to round load maintainer, impose alternate load in radial direction by oil circuit, and its frequency is 1-3 hertz, and power value is sinusoidal variations.The alternate load power that radially comes and goes that unitor 10 provides oil cylinder is delivered to and is hung on anti-vibration sleeve 8 by test specimen loading arm 4, will hang the real operating mode of anti-vibration sleeve 8 and simulate with dynamic-form, thereby can detect the Q-percentile life of test specimen.
Radial test frock of the present utility model, the test parameters such as its vibration frequency, amplitude are adjustable, are applicable to the product sampling observation of different model, have that volume is little, transmission efficiency is high, a test good stability, high reliability.
