Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of amphibious carrying equipment structure design and lightweight technology, and relates to an amphibious equivalent static load loading device of carrying equipment, which can simulate complex working conditions of the carrying equipment in an amphibious environment. BACKGROUND

[0002] With the continuous expansion of the application of modern carrying equipment in complex environments, especially in the fields of amphibious operations, scientific research and rescue, higher requirements are put forward for the stability and carrying capacity of equipment under different working conditions. In particular, in the design stage, how to load equivalent static load on the carrying equipment in the laboratory environment to simulate the load conditions in actual use has become an important link to ensure the performance and reliability of the equipment. The traditional loading device relies on a single static load test method, lacks adaptability and precision, and cannot meet the test requirements of multiple working conditions at the same time, especially in amphibious environments. Because the load responses of equipment are different in water and land, the existing technology is difficult to accurately simulate and test.

[0003] Therefore, a new type of loading device is needed, which can comprehensively consider the load characteristics of land and water environments, improve the universality and applicability of the test process while ensuring the experimental precision. The device not only has static load loading capacity, but also needs to have the function of adjusting and adapting to different working conditions to ensure that the load conditions in the amphibious environment can be fully and accurately simulated, providing reliable basis for the design and optimization of equipment.

[0012] The upper support (121) is bolted with the wheel shaft position of the wheels of the carrying equipment (160).

[0013] The portal frame (130) includes a cross beam and a column, and the cross beam and the column are connected by bolts;

[0014] The portal frame (130) is arranged at the front and rear of the carrying equipment (160);

[0015] The column of the portal frame (130) is arranged on both sides of the carrying equipment fixing support (120) and is rigidly connected with the ground;

[0019] The load transfer frame (150) includes a front load transfer frame (151) arranged at the front of the carrying equipment (160) and a rear load transfer frame (152) arranged at the rear of the carrying equipment (160);

[0020] The load transfer frame (150) is bolted between the load equipment (160) and can transfer the load of the force loading device (110).

[0021] The advantages of the present application are:

[0022] The device is designed for the requirements of high-speed amphibious load equipment in water and land multi-working condition cross-domain service, multi-field load floating, complex constraints, which leads to the difficulty of vehicle body structure stiffness, strength and lightweight design.
