Primary performance parameter testing
(1) Rigidity test of metal rubber block
Test target: the metal rubber block approximates a linear stiffness.
The testing method comprises the following steps: and (3) placing the metal rubber block in a shell of the metal rubber block, performing compression experiments on an experiment machine to obtain a force-displacement curve of the metal rubber block, performing linear fitting on the curve to obtain the approximate linear rigidity of the metal rubber block, and comparing the approximate linear rigidity with a design value.
The testing process comprises the following steps: two metal rubber blocks are placed in the grooves corresponding to the middle parts of the upper cover and the base of the net block and are horizontally placed on the supporting plate of the compressor. And controlling test software of the experimental machine to compress an upper pressing plate of the compressor at a speed of 10mm/min, and setting the force and displacement of the experimental machine to zero when the contact force between the upper pressing plate and the metal rubber block shell is 4kN, and compressing the upper pressing plate to 4kN from a newly defined compression starting point to obtain a force-displacement curve.
The carriage body suspension device is six sets of metal rubber net blocks which are simultaneously arranged between the frame and the carriage body, the mass of the carriage body of the vehicle is 3.47T, and the weight of each net block is about 289.2kg and the weight of the two metal rubber blocks is about 5784N when experiments are carried out on the assumption that the mass of the carriage body is uniformly shared by the net blocks. WhileWhen the particle swarm is optimized, the effective value of the vertical acceleration of the carriage body is as follows when the same road surface excitation condition is selected: 0.7m/s 2 According to the statistical principle, the maximum value of the acceleration is considered to be 0.7x6=4.2 m/s 2 The maximum value of the inertia force of the carriage body is 1.4574 multiplied by 10 4 N, also assuming that the net blocks uniformly share the inertial force, the inertial force of each net block is 1214.5N, and the inertial force of two net blocks is 2429N. The maximum pressure experienced by the two net blocks is approximately 8213N and the minimum pressure experienced by the two net blocks is approximately 3355N. In order to calculate the average linear stiffness of the metal rubber block, a force displacement curve is calculated for the rubber block bearing pressure of 4000N-8000N, and linear averaging is performed. Then, the experimental machine is used for slowly loading the net block to 4kN, which is equivalent to a pretightening force for the suspension system, and then 4kN of pressure is applied to the net block, and the true pressure applied to the net block is 8kN. To some extent, it is believed that the typical working range of pressures to which the net block is subjected in practice is between 4kN and 8kN. The force-displacement curve is derived from the newly defined zero point, and the force and the displacement are subjected to least square fitting, so that the approximate linear stiffness is obtained as follows: 1391N/mm, the result is the rigidity of two metal rubber net blocks connected in parallel, the value of the approximate linear rigidity is close to 1424N/mm compared with the result of the previous particle swarm optimization, and the rigidity of the metal rubber blocks is proved to meet the design requirement.
Because the designed suspension system mainly comprises an upper metal rubber block and a shell thereof, the strength of the shell is checked by a finite element method, and the design shape and the size of the shell are verified to meet the strength safety requirement, so that the shell with high metal rubber speed is ensured not to yield after the suspension system is arranged on a frame.
The detailed description of the van body suspension assembly with the flexible structure described above with reference to the embodiments is illustrative and not restrictive, and several embodiments may be enumerated in the limited scope, and thus, variations and modifications may be made without departing from the general inventive concept.
