Abstract

Recent emphasis in research and theory building on compassion in organizations has not yet received sustained attention by organization development and change scholarship. Compassion at work, however, has been reported as instrumental in coaching, ad hoc organizing, prosocial behavior during challenging times, and other processes central to developing and changing organizations. It also has been theorized to bring about an untapped organizational capability, contribute to fostering a climate of workplace forgiveness, and to facilitate development of social entrepreneurship. In this essay, we begin to outline what the recent advances in the compassion literature offer researchers and practitioners of organization development and change. We briefly review how compassion is defined across different contexts, how it can be seen through a positive lens and within broader lines of inquiry on social and emotional dynamics at work, and how interpretive approaches to studying compassion might fit with the study of change. Seeing compassion scholarship as more than a specialized trend in positive organizational behavior, we offer ample opportunities for diverse and novel inquiry into development and change at work.

Abstract

Purpose

To improve the load capacity and stability of gas foil journal bearings (GFJB), this paper aims to propose a novel GFJB with taper-grooved top foil.

Design/methodology/approach

A modified bump stiffness model is established considering rounding and friction. By considering the variation of clearance in the circumferential and axial direction, the static and dynamic characteristics of the novel bearing are calculated using the finite difference method, and perturbation method, respectively. The bearing performance under different groove parameters is studied and compared to the traditional bearings.

Findings

The results show that this novel GFJB can bring multi-extra local dynamic pressure and decrease the gas end leakage, which improves the static and dynamic properties. Moreover, as the increment of groove depth, the load capacity and direct stiffness are reinforced. There is an optimal groove width to maximize the load capacity, and the taper-groove is more beneficial to the improvement of bearing performance than other groove shapes. For the novel GFJB (Ng = 6, Hg = 10µm), the load capacity and direct stiffness increase by about 6.67 and 13.5 per cent, respectively. The stability threshold speed (STS) of a rotor supported by the novel bearings is also increased.

Originality/value

The performance of the presented novel GFJB is enhanced immensely compared to the traditional bearings, and the results are expected to be helpful to bearing designers, researchers and academicians concerned.

Abstract

This paper gives a review of the finite element techniques (FE) applied in the analysis and design of machine elements; bolts and screws, belts and chains, springs and dampers, brakes, gears, bearings, gaskets and seals are handled. The range of applications of finite elements on these subjects is extremely wide and cannot be presented in a single paper; therefore the aim of this paper is to give FE researchers/users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An Appendix included at the end of the paper presents a bibliography on finite element applications in the analysis/design of machine elements for 1977‐1997.
