“…Noted that though there were two pairs of flank sprockets, there was only one strip of chain, so only a pair of flank sprockets (either the right pair or the left pair) was at work at a time. Transmission sketches of reverse rotation and forward rotation were shown in (a) and (b) of fig.1 [3][4][5][6] Part design is the basis of 3 dimensional virtual design. In Solidworks, features are created from ways such as extrude, revolve, sweep, etc., and then combined together according to constraint relations to form parts.…”

In the paper, the necessity of root stubble harvesting and recycling was put forward from the perspective of biomass energy utilization. To accomplish mechanized harvesting on root stubble, a rotary digging machine was designed based on parametric modeling software Solidworks. Firstly, parts were built under entity modeling module, and then assembled to 4 main mechanisms in assembling environment. Secondly, mechanisms including frame, transmission mechanism, suspension mechanism and digging mechanism were assembled together to establish the whole prototype on which interference checking was done. Through manual change of the transmission chain's installation position, the digging mechanism was able to shift between reverse and forward rotation according to different soil conditions. Finally, relevant 2-D engineering drawings were generated for manufacture. The paper provides methodological reference for the design of similar machines and preparation for further simulation and analysis of the designed models.

“…Currently these methods are the industrial standards to be used to compare with other new proposed discrimination methods, such as the pulse gradient analysis (PGA) [9,10,11] method, wh ich is based on the comparison of the relative heights of samples in the trailing edge of the pulse, and curve-fitting method [12]. [13,14] which exh ibited a strong insensitivity to the variation in pu lse response of the PMT. can be used to simu late the response.…”

A novel algorithm for the discrimination of neutron and γ-ray with wavelet transform modulus maximum (WTMM) in an organic scintillation has been investigated. Voltage pulses arisin g from a BC501A organic liquid scintillation detector in a mixed radiation field have been recorded with a fast digital sampling oscilloscope. The performances of most pulse shape discrimination methods in scintillation detection systems using time-domain features of the pulses are affected intensively by noise. However, the WTMM method using frequency -domain features exhibits a strong insensitivity to noise and can be used to discriminate neutron and γ-ray events based on their different asymptotic decay trend between the positive modulus maximum curve and the negative modulus maximum curve in the scale-space plane. This technique has been verified by the corresponding mixed-field data assessed by the time-of-flight (TOF) method and the frequency gradient analysis (FGA) method. It is shown that the characterization of neutron and gamma achieved by the discrimination method based on WTMM is consistent with that afforded by TOF and better than FGA.Moreover, because the WTMM method is itself presented to eliminate the noise, there is no need to make any pretreatment for the pulses.

A superconducting focusing solenoid has been designed and developed for the China Accelerator Driven System (CADS). In order to meet the requirement of focusing strength and fringe field while minimizing the physical size of the solenoid, the novel optimizing design method based on a linear programming method was employed. In this report, the design of the solenoid including magnetic field optimization, mechanical design and quench protection will be introduced. The solenoid has been fabricated and tested. The testing results show that the central field reached 8.4 T and the stray field was lower than 50 Gauss in the cavity zone.
