Jinan Yiu Cheung Trading Company during the cab strength, stiffness and subsequent analysis of passive safety in the heavy truck cab with 4 point suspension stiffness and damping suspension imposed constraints China's heavy truck cab assembly, in cab suspension imposed constraints and the frame fixed connection point to simulate the actual vehicle cab suspension system support and restraint conditions. Analysis of the cab to work in the most severe operating conditions under load BIW structural strength and stiffness, lightweight design as the basis for comparison after the original cab. Heavy truck cab in steady rotation, acceleration and braking conditions, the maximum stress is less than the corresponding material allowable stress, structural strength to meet the requirements; maximum deformation to meet the design requirements. On the basis of the cab BIW finite element model, the establishment of a topology optimization analysis model cab BIW. Heavy truck cab fixture clamping unit structure generally consists of bearing, the clamping element (cylinder), briquetting and positioning blocks. Supports choices are common parts, cylinder is purchased parts. Designers by positioning requirements according to truncate only compact design and positioning blocks can be. Locating and clamping unit versatile, reliable structure, good processing, manufacturing precision easy to ensure easy adjustment and measurement, easy handling and so on. After such a high precision boring unit by installing fixtures on the floor, you can ensure that products on the jig positioning accuracy heavy truck cab, cab assembly to ensure accuracy. This fixture uses 81 locating and clamping units. When the front and rear heavy truck cab Wai Wai were fixtures in the horizontal position, the pieces of equipment to the front and rear Wai Wai assemblies were loaded into the fixture. In order to ensure the accuracy of self-piece heavy truck cab accessories, equipped with assembly contours coincide guide mechanism in the fixture, guided by weldment accurately into the positioning element. Also fitted is in place to determine the positioning signal switch, only when it is in the exact position weldment Shandong heavy truck cab, only to clamp switch position switch signal, when the automatic clamping fixture can only continue the action.
