According to customer feedback on market operating vehicles, the crack location is at the pre-embedded brackets on the left and right top covers. The currently designed bracket and the glass fiber reinforced plastic contact surface is 60mm*50mm. If there is a high speed bump on the operating road, the bracket may be subjected to The concentrated stress formed by the external force from the road bumps on the surface of the left and right top cover glass fiber reinforced plastic exceeds the bearing capacity of the glass fiber reinforced plastic, which requires further analysis.

根据客户反馈的市场运营车辆的情况，开裂位置在左右顶罩上的预埋支架处，目前设计的支架与玻璃钢接触面为60mm*50mm，如果运营道路存在较高的减速带可能会使得支架承受来自路面颠簸的外力在左右顶罩玻璃钢表面形成的集中应力超过了玻璃钢的承受力，需要进一步分析。<br>

According to the situation of vehicles operating in the market fed back by customers, the cracking position is at the embedded bracket on the left and right top covers, and the contact surface between the bracket and FRP is 60mm*50mm at present. If there is a high speed bump on the operating road, the concentrated stress formed on the FRP surface of the left and right top covers under the external force from road bumps may exceed the bearing capacity of FRP, which needs further analysis.
