Heavy-duty dump truck traveling in the harsh environment of Chinese-highway heavy truck cab pictures, overturned cab when the impact load is great, it will directly affect the strength of the cab driver's safety. In recent years, the dump truck cab design process began to consider the strength of the problem, but often neglected to optimize its structure. Prince cab cab in ensuring the strength and deformation meet certain requirements under the premise of reducing the quality of Shandong heavy truck cab cab, in order to achieve both security and economic purposes. Through targeted optimization to select different combinations to achieve the balance between safety and economic purposes. Through analysis and optimization of the cab before the comparison, to meet the strength requirements of the premise, the cab obvious weight loss, improve the economic efficiency of enterprises.

In the selection process, the following questions need to consider the issue. 1. cab suspension system a good fit issues stiffness, damping values ??with the main suspension stiffness, damping values. 2. cab suspension system variables other parameters such as elastic element decorative embellishment safe position, partial suspension rod front suspension and rear suspension systems installation position and the length of the rod, also has some influence on the cab stability. 3. The other point parametric commercial heavy truck cab accessories, mainly covers the vehicle structure parameter variables (such as ministers, front suspension, wheelbase, track width, etc.), the quality of the reference variable (such as quality control room, centroid location, moment of inertia etc.) will also affect the stability of the control room.
