A jump-connected double-table horizontal hydraulic vibrating table

Abstract

A double-table horizontal hydraulic vibration table with a jumper, characterized in that: the hydraulic actuator (21) is a double-acting double-rod actuator, and is located in the middle of the long bottom direction of the base, and its two outputs The rods (211, 212) protrude toward both ends of the base (100) in the length direction; there are two tables: a first table (4) and a second table (5), and the first table (4) and The second table (5) is separately arranged on both sides of the hydraulic actuator (21) in the length direction of the base, and the first table (4) is fixedly connected with an output rod (211) of the hydraulic actuator (21), The second platform (5) is fixedly connected with another output rod (212) of the hydraulic cylinder (21). The invention has three working modes of specifications, is suitable for horizontal vibration tests under multi-standard test pieces and multi-test indicators, has simple structure, stable performance, and convenient operation, making the product testing process efficient and fast.

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...

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
