Seat power test device for high-speed ships and test method thereof

Abstract

The invention relates to a seat power test device for high-speed ships and a test method thereof. The device comprises a mechanical table body. A tested sample is mounted on the mechanical table body,and actuation is performed according to an instruction of a control signal. One end of the mechanical table body is connected with a hydraulic oil source through an oil pipe, and the hydraulic oil source provides power needed by the actuation of the device. The device further comprises a measurement and control system which is connected with the hydraulic oil source and the mechanical table body.The measurement and control system is used for outputting control signals and collecting and analyzing measurement signals. The device has the advantages of accurate output load, stable actuation process, high degree of refinement, convenience of use and good test effect.

Description

technical field [0001] The invention relates to the technical field of test devices, in particular to a dynamic test device for high-speed ship seats and a test method thereof. Background technique [0002] The mechanical environmental test is mainly to simulate the mechanical environmental conditions that the product may encounter during the full-life working period, to examine whether the product can meet the development purpose and use requirements, to carry out the mechanical environmental test correctly and effectively, and to be able to inspect and evaluate the durability of the product under rated mechanical environmental conditions. Ability to provide a basis for product improvement and optimization. [0003] The impact test in the mechanical environment test is generally used to investigate the impact resistance and characteristics of the product under impact conditions such as drop and collision during transportation and use, and to evaluate the safety of the produ...

Problems solved by technology

[0006] (1) The 2000 "International High-Speed ​​Craft Safety Regulations" requires that the test load level for the dynamic test of high-speed craft seats not exceed 1g, and the load capacity provided by the existing general impact test equipment capable of carrying seat products under conventional test conditions The level is much higher than the requirements of the 2000 "International High-Speed ​​Ship Safety Code", and it cannot stably output the load conditions that meet the requirements of the high-speed ship seat dynamic test.

[0007] (2) The existing general-purpose impact test equipment whose output test load level meets the requirements of the 2000 "International High-speed Craft Safety Code" is all small-scale test equipment for component level, and the load-carrying capacity cannot meet the test requirements of seat products ( Including the use of 50% simulation test dummies), and the small test equipment is limited by the overall scale, the platform displacement capacity is generally small, and the output test load pulse width is also difficult to meet the requirements of the 2000 International Code of Safety for High-Speed ​​Craft

[0008] (3) For the existing impact test equipment, how to ensure the repeatability of the test load and avoid the load waveform out-of-tolerance caused by the frequency response of the local structure when implementing the dynamic test of the high-speed ship seat according to the 2000 "International High-speed Ship Safety Code" There are insurmountable difficulties in such issues as these, which will eventually have an uncontrollable impact on the efficiency, effect and reproducibility of high-speed ship seat dynamic tests
