Specifeca tion speeification is tested
(1) metal-rubber block rigidity test
Test target：Metal-rubber block approximately linear rigidity.
Method of testing：Metal-rubber block is placed in its shell, compression experiment is carried out in experimental machine, obtains metal-rubber
The force-displacement curve of block, linear fit is carried out to curve, obtains the approximately linear rigidity of metal-rubber block, is carried out with design load
Contrast.
Test process：Two pieces of metal-rubber blocks are placed in the groove corresponding among the upper lid and bottom seat of net block, kept flat
On the supporting plate of compressor.Experimental machine test software is controlled, the top board of compressor is treated with 10mm/min speed compression
When pressing plate and metal-rubber block shell contact force are 4kN, by the power of experimental machine and displacement zero setting, starting point is compressed from new definition, then
4kN is compressed to, obtains force-displacement curve.
Carriage body suspending apparatus is placed between vehicle frame and carriage body simultaneously for six sets, totally ten two upper metal-rubber net blocks, vehicle
Carriage body quality is 3.47T, it is assumed that each net block uniformly shares carriage body quality, then each the carrying quality of net block is about
289.2kg, then the gravity suffered by two pieces of metal-rubber blocks when testing is about 5784N.And in particle group optimizing, selection
The vertical acceleration virtual value of carriage body is during identical road excitation condition：0.7m/s2, according to Principle of Statistics, it is believed that acceleration
Maximum be 0.7 × 6=4.2m/s2, then the inertia force of carriage body be most worth for 1.4574 × 104N, it is also assumed that each net block is equal
Even to share this inertia force, then the carrying inertia force of each net block is 1214.5N, and the inertia force of two net block carryings is 2429N.
The maximum pressure that then two net blocks are born is about 8213N, and the minimum pressure that two pieces of net blocks are born is about 3355N.In order to
The average linear rigidity of metal-rubber block is calculated, block rubber is calculated and bears the power displacement curve that pressure is 4000N-8000N, carry out
Linear averaging.So, application experiment machine carries out slow pressure-loaded to net block to 4kN, equivalent to giving suspension system one pretension
Power, then the pressure to net block application 4kN, the true pressure of net block is 8kN.To a certain extent it is believed that net in practice
The conventional working range of block pressure is in 4kN-8kN.By it is above-mentioned from it is new define zero point after force-displacement curve export, to power and
Displacement carries out least square fitting, and the approximately linear rigidity obtained herein is：1391N/mm, this result are two metal-rubber nets
Block rigidity in parallel, the result of the value of approximately linear rigidity and particle group optimizing before is close to 1424N/mm, it was demonstrated that this metal rubber
The rigidity of blob of viscose meets design requirement.
Because the designed main stressed member of suspension system is upper metal-rubber block and its shell, so using finite element
Method to its shell carry out strength check, verify its shell design shape size meet Strength Safety requirement, ensure suspension
The fast shell of metal-rubber will not be surrendered after system is arranged on vehicle frame.
The above-mentioned detailed description carried out with reference to embodiment to a kind of van type carriage body mounting assembly with flexible structure,
It is illustrative rather than limited, several embodiments can be included according to limited scope, therefore do not departing from this hair
Changing and modifications under bright general plotting, it should belong within protection scope of the present invention.
