This invention provides a light-transmitting housing for a lidar and the lidar itself. The light-transmitting housing has a rotationally symmetric structure about the lidar's axis of rotation. The inner surface of the housing is parabolic, and its cross-section along the axis of rotation forms a parabola. The outer surface of the housing, on the cross-section along the axis of rotation, is an even-order aspherical shape corresponding to the parabola. The coordinate system used in the equation of the even-order aspherical shape has its z-axis parallel to the axis of rotation, and the planes containing the x-axis and y-axis of the coordinate system are parallel to the lidar scanning plane. The even-order aspherical shape ensures that a light beam emitted from any height parallel to the x-axis within the xz-cross-section along the axis of rotation is emitted parallel to the x-axis. The defocusing position of the lidar's light source ensures that the absolute value of the difference between the first divergence angle and the second divergence angle is less than a preset threshold. This invention solves the problem of beam deflection and divergence affecting beam transmission characteristics, thus improving the overall performance of the lidar.

The application provides a machine tool support structure design method, device, equipment and medium, and relates to the technical field of data processing, wherein the method comprises the following steps: constructing a finite element model of a machine tool support structure, and defining a design region in the finite element model; determining weight values corresponding to pose change information of a moving part in each operating condition; based on the weight values, a design response index determined according to a design requirement index of the support structure, a target function and a constraint condition, performing optimization design of the design region in the finite element model, and determining a design result of the support structure. By integrating the components and component junctions of the support structure into a unified design region, considering the weights of the machine tool under multiple operating conditions, and performing collaborative topology optimization, the defects of stiffness mismatch between the structures caused by separate design are solved, the stiffness matching between the structures after optimization design is ensured, and the design accuracy and performance of the machine tool support structure are improved.
