Embodiment Construction

[0023] In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The present invention aims at the inherent static unbalance of the tire itself, and analyzes the detection results through the vector calculation method, and analyzes the three inevitable key factors affecting the static balance in the tire manufacturing process (1# cord joint, PA joint, tire Surface joints) for accurate calculations, so as to directly obtain the ideal improvement plan.

[0025] refer to figure 1 , mainly includes the following steps: step S1, forming process: pre-selecting the joint distribution scheme, and making a test embryo; step S2, vulcanization, detection and screening, including the following steps: step S21, performing single-mode fixed-point vulcanization treatment on the test embryo to Reduce the variabl...

Abstract

The invention relates to a tyre static unbalance improvement method based on vector calculation. The method comprises the following steps: S1) carrying out forming process; S2) carrying out vulcanization, detection and screening; S3) measuring and calculating the position of each joint with respect to a static imbalance heavy point, the static imbalance heavy point being in a 180-degree angle with a static imbalance light point; S4) obtaining influence of each joint on static unbalance according to vector analysis; and S5) based on the calculation result above, reasonably arranging the joints according to the parallelogram law. For the problem of inherent static unbalance of each tyre itself, the method carries out analysis on the detection result through a vector calculation method, and carries out accurate calculation on three unavoidable key factors (1# cord joint, PA joint and tyre surface joint) affecting the static unbalance in the manufacturing process, so that an ideal improvement scheme can be obtained directly; in the implementation process, effects of short time, high efficiency and easy operation are achieved; and the obtained adjustment scheme is supported by accurate technical support.

Description

technical field [0001] The invention belongs to a calculation method for improving tire dynamic balance, and relates to the adjustment and improvement of inherent static unbalance generated in the tire manufacturing process. Background technique [0002] Part joints are inevitable in the tire manufacturing process, and the appearance of part joints has an impact on the static balance of tires. Existing countermeasures to improve the static unbalance of tires are simply relying on the key distribution of the static unbalance shown in the detection, and conducting multi-plan joint distribution test demonstrations. The most important three joints (tread joints, PA joints, 1# tire joints) Body joints) are distributed in the direction of 360 degrees around the tire, which will produce multiple schemes. The existing method needs to test multiple joint distribution schemes, that is, to test irregularly. Each scheme requires multiple test tires to track and record data. Then select...
