Problems solved by technology

Such a structure has the following defects: when connecting the test piece, it must be ensured that the table top of the hydraulic vibration test bench 7 is consistent with the table displacement center point of the unpowered sliding table 8, otherwise the guide rail of the table top will be damaged, and the test piece may even be damaged. Precise adjustment is required every time the specimen is clamped, which is very troublesome

Embodiment

[0031] Example: see Figure 2-9 Shown:

[0032] A jump-connected double-table horizontal hydraulic vibration table includes a base 100 , a servo hydraulic actuator 2 and a table slid on the base 100 via a guide rail 3 .

[0033] see Figure 2-9 As shown, the servo hydraulic actuator 2 includes a hydraulic cylinder 21 , an electro-hydraulic servo valve 22 and a sensor 23 . The hydraulic actuator 21 is a double-acting double-rod actuator, and is located in the middle of the base in the direction of the long bottom. There are two tables: a first table 4 and a second table 5, and the first table 4 and the second table 5 are respectively arranged on both sides of the hydraulic cylinder 21 in the length direction of the base, preferably the second table 5 is designed to be larger than the first table top 4 size. The first platform 4 is fixedly connected to an output rod 211 of the hydraulic cylinder 21 , and the second platform 5 is fixedly connected to another output rod 212 of...

Abstract

The invention discloses a tripping-type double-tabletop horizontal hydraulic vibration table. The tripping-type double-tabletop horizontal hydraulic vibration table is characterized in that a hydraulic actuator cylinder (21) serves as a double-acting double-rod actuator cylinder and is arranged in the middle of the length direction of a base (100); two actuating rods (211, 212) of the hydraulic actuator cylinder (21) extend toward two ends of the length direction of the base (100); a first tabletop (4) and a second tabletop (5) are respectively arranged on two sides of the hydraulic actuator cylinder (21) on the length direction of the base (100), the first tabletop (4) is fixedly connected with the actuating rod (211), and the second tabletop (5) is fixedly connected with the actuating rod (212). The tripping-type double-table horizontal hydraulic vibration table is imparted three-standard operating modes, applicable to horizontal vibration test with multi-standard test pieces and multiple test indexes, simple in structure, stable in performance and convenient to operate and allows the product to be efficiently and quickly tested.

Description

technical field [0001] The invention relates to the field of environmental mechanics test equipment, in particular to a jump-connected double-table horizontal hydraulic vibration table. Background technique [0002] The hydraulic vibration table belongs to a kind of mechanical environment test equipment, also known as the electro-hydraulic vibration table, which is mainly used to simulate the vibration environment of the product during use, loading and unloading and transportation, so as to determine the adaptability of the product to various vibrations. Through such a vibration test, the integrity of a product structure and the rationality of the working performance index parameters can be assessed, providing a reasonable basis for assessing the quality of the product. It is commonly used in precision products such as aerospace, but also in auto parts and instrumentation electronics. [0003] Existing horizontal hydraulic vibration test benches all have a single table stru...
