A controller for a motorised vehicle is provided which is arranged to receive control signals from a user input device and the controller is configured to control a motor arrangement of the motorised vehicle in dependence on the control signals. The controller comprises an acceleration control unit configured to determine a centripetal force factor corresponding to a centripetal force which is currently acting on said motorised vehicle as a result of the control signals and is configured to calculate an acceleration limit for the motorised vehicle in dependence on the centripetal force factor. The acceleration control unit is configured to apply the acceleration limit by modifying a response of the controller to the control signals, such that the motorised vehicle does not exceed the acceleration limit.

Provided is a sub-conductive wire spacing bar which comprises a polygon framework and a wire clamp body which is connected with the framework. The head end part of the wire clamp body presents to be a hooked shape. The internal arc surface of the hook is provided with an elastic anti-skid protective mat.

The invention provides a five-blade polycrystalline diamond compact bit. Two main blades and three auxiliary blades form an outline in a circular arc shape. Fewer cutting teeth are arranged at the position close to the center of the bit. More cutting teeth are arranged at the position close to the edge of the bit. The cutting teeth in the first row are tunneling teeth. The cutting teeth in the second row are ploughing teeth. The tops of the tunneling teeth are in a pointed arch shape, and the tops of the pointed arches incline towards one side of the center of the bit. Broaching teeth are in a disc shape. Stabilizing teeth are in a strip shape. Through the design of the arc-shaped blades, the tooth profile design of the tunneling teeth and the arrangement of all the cutting teeth, the five-blade polycrystalline diamond compact bit can conduct chip removal initiatively in the drilling process, the working temperature of the cutting teeth is lowered, the working conditions of the cutting teeth are improved, and the balling phenomenon is not likely to occur; through the tooth profile design of the tunneling teeth, the crushing capacity of the bit is improved, the centripetal force of the bit is increased, and the drilling quality is improved; meanwhile, all the cutting teeth are stressed uniformly, and the service life of the bit is prolonged; through the arrangement of the initiatively guided stabilizing teeth, the guiding property of the bit is good, and the anti-vortex-motion performance of the bit is improved.

A combined laser strengthening method for a ramp / curve rail and turnout assembly and a straight road rail and turnout assembly includes that various positions of the ramp / curve rail and turnout assembly are subjected to viscosity-increasing strengthening with equal strengthening depths; various positions of the straight road rail and turnout assembly are subjected to viscosity-reducing strengthening with equal strengthening depths; the strengthening depths of the viscosity-increasing strengthening and the strengthening depths of the viscosity-reducing strengthening are equal and are larger than or equal to wheel-rail rolling contact fatigue influence depths; and the strengthening depths are defined as thicknesses of phase-change structures of surface layers of materials due to the laser strengthening, in other words, distances from interfaces of the phase-change structures and matrix structures to surfaces of the materials. The combined laser strengthening method has the advantages that after being strengthened by the combined laser strengthening method, rails and turnouts in a total section are high in service life matching, long in service life, high in reliability and convenient to use and maintain, the driving tractive capacity of a train can be improved, and energy consumption of the train during running is reduced.
