Meanwhile, experimental verification of theories is conducted in the earlier stage of automobile design and development, the manufacturing cost of a body in white is reduced, a research method is provided for research and development of similar products, and research and development reference standards are provided.
Description
Technical field
The present invention relates to a kind of method optimizing sliding door of automobile switch gate power based on test-bed, belong to automobile and manufacture detection technique field.
Background technology
As a rule, vehicle switch Men Li is divided into door handle releasing force and switch gate process opening force, and involved in the present invention is switch gate process opening force and closing forces.Automotive hinge door is optimized in the method for switch gate power, can be realized by methods such as the structures of optimization hinge axes, optimization stop.
For sliding door of automobile, the optimization of switch gate power can only draw some empirical values by constantly testing.A lot of main engine plants do not optimize switch gate power in the design process, until vehicle rolls off the production line, do experiment or vehicle is about to listing time just find switch gate power too greatly or switch gate have some setbacks, generally can only by the solution to the moving parts transformation of the way, such as increase sliding door traveling wheel arm roller and guide clearance, change a kind of reasonable traveling wheel arm roller material, or on kinematic pair apply oil etc.These methods are not the best approaches that sliding door switch gate power is optimized.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of method optimizing sliding door of automobile switch gate power based on test-bed, mainly comprise: first, multifunctional test bed by sliding door, in conjunction with sliding door kinetic characteristic, make the contact of sliding door traveling wheel arm and guide rail at rational forced position, just sliding door switch gate power is optimized early stage in research and development of products, at utmost reduces switch gate force value.Secondly, in the design process, on sliding door, in and lower three guide rails have certain angular relationship, due to foozle, to cause on sliding door, in and lower three guide rails deviate from design load, make switch gate process switch gate power become large.The current testing table scope of application is comparatively single-minded, and regulate inconvenient in discovery, for the user of vehicle, switch gate power is that they feel with car first, so optimize switch gate power to become one of important indicator of sliding door design.And the present invention by adjustment stand, sliding door to be moved when switch gate smooth-going, at utmost reduce switch gate power, to improve the quality of products.
Technical conceive of the present invention is: according to related requests such as sliding door aperture size, sliding door weight, guide rail layout and travelling wheel arm structures as initial conditions, governor motion and force application mechanism are separated and works, the parts relevant to force adopt high-strength design, regulate relevant parts to be attached on force application mechanism; In motion process, determine the gap between traveling wheel arm and guide rail, to determine adjustment amount, avoid intensive work.Placement sensor on sliding door, sensor is detected by sliding door motion and draws the movement velocity of sliding door in motion process, shown by sliding door movement velocity curve whether sliding door is smooth-going in switching process, judges how to adjust sliding door guide rail and traveling wheel arm with this.By the size using the measurement data of sensor objectively can judge switch sliding door power, reduce traditional manual measurement switch sliding door power Size Error, and just can adjust guide rail on test-bed, the work of clamping can be alleviated repeatedly.
