Embodiment Construction
[0020] In the present invention, the strain gauge force-measuring support seat of the integrated transmission device of armored vehicles selects a representative support seat that is relatively difficult to test as an entry point, and develops strain sensing technology at key parts of the comprehensive transmission device to develop a device that can be integrated into the transmission support. The new sensing technology in the test is used to obtain test data, and then solve the problem of difficulty in obtaining the support force of the transmission integrated transmission device.
[0021] The supporting seat of the integrated transmission device is located in a narrow space, and it is difficult to install various types of sensors. The present invention uses strain testing to make the test results more accurate.
[0022] The principle of the strain test method is: Accurately obtain the strain signal of the key parts of the transmission support through the high-precision high-...

Abstract
The invention discloses an integrated transmission device strain gage force measurement supporting seat for an armored vehicle, and the seat comprises a support seat. The lower part of the front side of the support seat is provided with a bottom supporting plate, and the top end of the support seat is provided with a semicircular arc-surface groove, wherein the radius of the internal surface of the groove is 215mm+ / -3mm, and the central line of the groove is located in a left / right horizontal direction. The surface of the left end or right end of the support seat is provided with a first pre-assembly line type strain gage, a second pre-assembly line type strain gage and a third pre-assembly line type strain gage. The invention aims at providing the seat which can accurately obtain the dynamic testing data of a vehicle under the outdoor real work conditions, solves a problem of simulation and testing conformity in a vehicle design, achieves the integrated research and development mode of design, simulation and testing of a novel supporting structure and an integrated transmission device, and speeds up the digitalized design process of a vehicle chassis.
Description
technical field [0001] The invention relates to a strain gauge force-measuring support seat of an armored vehicle comprehensive transmission device. Background technique [0002] During the operation of the tracked armored vehicle, with the working load of the comprehensive transmission device itself and the impact of the ground, the comprehensive transmission device will generate a large force on the vehicle body, and the magnitude and direction of the force will vary with the driving conditions. vary. The current integrated transmission device and the car body are connected through the support seat, and the force on the support seat is the load of the integrated transmission device on the car body. Therefore, obtaining the load of the support seat during the operation of the equipment under different working conditions is of great importance to the vehicle chassis structure. Optimal design is extremely important. Conversely, the comprehensive transmission device is insta...
